Storage minimizes the intermittent nature of renewable sources. Solar and wind are the two fostered source of renewable energy. However, the availability of useful solar radiation and wind speed varies with geographical locations, and also the duration of this energy sources varies with seasonal variation. With the available vast open land and geographical position, Australia has great potential for both solar and wind energies. However, both these sources require energy buffering to support load demand to ensure required power quality. Electricity demand is increasing gradually, and also Australia has target to achieve 20% electricity from renewable sources by 2020. For effective utilization of solar and wind energy potential location of these sources needs to be identified, and effective size of storage needs to be estimated for best utilization according to the load demand. Therefore this paper investigated wind speed and solar radiation data of 210 locations in Australia, identified the potential locations, and estimated required storage in various potential locations to support residential load demand. Advantages of storage were analyzed in terms of loading on distribution transformer and storage support during energy fluctuation from renewable energy. Further analysis showed that storage greatly reduces greenhouse gas emission and reduces overall cost of energy by maximizing the use of solar and wind energies.

In Tasmania, the island state of Australia, the generator, Hydro Tasmania, is pushing technical, environmental and business boundaries in its plans to integrate a relatively high proportion (up to 20 percent) of large wind generators into its current complex mix of large and small hydropower plants. Its plans include projects to increase the efficiency of its older hydropower equipment as it prepares to supply much needed peaking capacity to the market in southern Australia via the groundbreaking Basslink undersea cable, which is due for completion in November 2005. Taken as a package these developments are creating a globally significant reference site for renewable energy systems. The paper will describe what is happening, and more importantly what is underpinning the developments, including: the harnessing of Tasmania's world-class wind resource, where recently constructed 1.75 MW wind turbines are achieving capacity factors of over 45 percent – some of the best productivity in the world today; the application of leading environmental science measures to ensure the sustainability of both the new wind farm developments and the transformation of the hydropower system to meet peak capacity demands; the relevance of the existing large hydropower storages that can operate in synergy with the wind resource; the contribution of Australia's renewable energy certificate scheme, which is effectively doubling the value of new renewable energy developments compared with existing generation sources; the application of the latest technology in hydropower turbines, combined with power system expertise from the world's leading manufacturers, to increase the efficiency of older hydropower generators, thereby more effectively harnessing the existing environmental footprint; and the transformation of Hydro Tasmania's business into a significant supplier and trader of premium value peak energy into the sophisticated Australian National Electricity Market.

Purpose Australia is one of the ten largest emitters of greenhouse gases but stands out from the others due to its economic growth without recession for 26 consecutive years. This paper aims to focus on the energy-growth nexus and the effects of energy consumption on the environment in Australia. Design/methodology/approach This analysis is performed using annual data from 1965 to 2015 and the autoregressive distributed lag model. Findings The paper finds empirical evidence of a trade-off between economic growth and carbon dioxide (CO2) intensity. The results show that increased gross domestic product (GDP) in Australia increased investment in renewable energy sources (RESs), although the renewable technology is limited and has no impact on reducing CO2 intensity in the long run. In contrast to investment in RES, fossil fuels, coal and oil, are decreased by GDP. However, oil consumption increased renewable energy consumption, and this reflects the pervading effect of the growing economy. Originality/value Overall, this paper contributes to the literature by analysing the behaviour of both energy consumption and the environment on the growing Australian economy. In addition, this paper goes further by studying the impact of economic growth on renewable and non-renewable energy consumption, as well as on CO2 emissions. The study is conducted on a single country for which literature is scarce, using a recent approach and a long time period.

Abstract In this study, the authors carried out a detailed analysis of the technologies required for successful implementation of a sustainable renewable energy household power supply in Papua New Guinea or PNG (PNG is a Pacific Island nation, North of Australia) to free the country from fossil fuel dependency. The role of renewable energy sources in the recent PNG National Energy Policy covering 2018 to 2050 (unveiled at the 2018 March Energy Summit in Port Moresby by the PNG Minister of Energy) was also analysed. From the outcome of our recently concluded SERI 2018 Renewable Energy conference, we assembled into a single hypothetical ‘energy basket’ all the varied renewable ‘green’ energy sources within PNG (as estimated by our energy research groups). This paper estimates that there is sufficient renewable energy in PNG and advocates that these available green energy sources should be tapped, for they can go a long way in the quest for climate change mitigation. This research paper will articulate that shifting PNG’s and other Pacific Island nations’ energy reliance from fossil fuels and other non-renewable sources to renewable green and environmentally sustainable sources is not only achievable, but feasible within a reasonable time.

In Australia, exploitation of shale gas is at an early stage. Western Australia has estimated its technically recoverable gas resources at 235 trillion cubic feet (tcf). It is viewed as an exciting economic prospect and decarbonising option for transition to climate change mitigation. The central focus of this paper is to estimate the climate impacts of Australian shale gas fracking and compare with other energy sources. Electricity generation has been considered as end use of gas in export scenarios to Japan and China. Analysis has been done for resource development periods of 20 and 40 years. Carbon footprints of shale gas range from 604MtCO2e to 543 MtCO2e per annum for China and Japan export cases, respectively, for 20 years field lifetime, if 66 tcf of shale gas is exploited and used. This result is roughly equivalent to 115% of Australia's total national emissions for the year 2014. If all technically recoverable shale gas (235tcf) from the Canning Basin in the Kimberley is exploited and exported to China and Japan over 40 years, the annual emissions are double the total Australian national emissions. The result suggests that shale gas has low carbon intensity compared to coal and oil but solar PV and wind are much cleaner energy options for GHG mitigation. The solar PV and wind electricity would produce 8% and 5% of the shale gas electricity emissions, respectively. Unless accompanied by stringent regulation and compliance on the upstream resource development, stage shale gas cannot be an appropriate energy source for sustainable development as opposed to renewable energy sources.

Harnessing sustainably sourced forest biomass for renewable energy is well-established in some parts of the developed world. Forest-based bioenergy has the potential to offset carbon dioxide emissions from fossil fuels, thereby playing a role in climate change mitigation. Despite having an established commercial forestry industry, with large quantities of residue generated each year, there is limited use for forest biomass for renewable energy in Queensland, and Australia more broadly. The objective of this study was to identify the carbon dioxide mitigation potential of replacing fossil fuels with bioenergy generated from forest harvest residues harnessed from commercial plantations of Pinus species in southeast Queensland. An empirical-based full carbon accounting model (FullCAM) was used to simulate the accumulation of carbon in harvest residues. The results from the FullCAM modelling were further analysed to identify the energy substitution and greenhouse gas (GHG) emissions offsets of three bioenergy scenarios. The results of the analysis suggest that the greatest opportunity to avoid or offset emissions is achieved when combined heat and power using residue feedstocks replaces coal-fired electricity. The results of this study suggest that forest residue bioenergy is a viable alternative to traditional energy sources, offering substantive emission reductions, with the potential to contribute towards renewable energy and emission reduction targets in Queensland. The approach used in this case study will be valuable to other regions exploring bioenergy generation from forest or other biomass residues.

Climate change and air pollution are among the key drivers of energy transition worldwide. The adoption of renewable resources can act as a peacemaker and give stability regarding the damaging effects of fossil fuels challenging public health as well as the tension made between countries in global prices of oil and gas. Understanding the potential and capabilities to produce renewable energy resources is a crucial pre-requisite for countries to utilize them and to scale up clean and stable sources of electricity generation. This paper presents a hybrid methodology that combines the data envelopment analysis (DEA) Window model, and fuzzy technique for order of preference by similarity to ideal solution (FTOPSIS) in order to evaluate the capabilities of 42 countries in terms of renewable energy production potential. Based on three inputs (population, total energy consumption, and total renewable energy capacity) and two outputs (gross domestic product and total energy production), DEA window analysis chose the list of potential countries, including Norway, United Kingdom, Kuwait, Australia, Netherlands, United Arab Emirates, United States, Japan, Colombia, and Italy. Following that, the FTOPSIS model pointed out the top three countries (United States, Japan, and Australia) that have the greatest capabilities in producing renewable energies based on five main criteria, which are available resources, energy security, technological infrastructure, economic stability, and social acceptance. This paper aims to offer an evaluation method for countries to understand their potential of renewable energy production in designing stimulus packages for a cleaner energy future, thereby accelerating sustainable development.

Desert/remote Australia is blessed with abundant natural energy resources from solar, geothermal and other renewable sources. If these were harnessed and connected appropriately desert/remote Australia could be not only energy self-sufficient but a net exporter. Generation of abundant, clean energy can also attract energy-intensive industries and provide local income and employment. Such co-benefits should be included in any cost-benefit analysis. Regardless of renewable energy’s contribution to reducing climate change, the world is already committed to global warming and associated climate changes. Desert/remote Australia will thus inevitably get warmer, with implications for health, energy demand and other issues, and may be subject to increased extremes such as flooding, longer dry spells, more severe storms and coastal inundation. In addition, the prospect of world demand for oil from conventional sources exceeding supply will likely lead to oil shortages, higher oil prices, and additional incentives to provide alternative energy supplies. The region is heavily reliant on diesel generators and fossil fuel-powered motor vehicles and airplanes for transport for within-region mobility, the importation of goods, the tourism industry and emergency medical services. Without adaptation, climate change and peak oil will make living in desert/remote Australia less attractive, resulting in increased difficulty of attracting and retaining skilled workers, which would constrain development. This paper focuses on the climate and energy-related impacts and potential responses. These are both a challenge and an opportunity. They could provide additional employment and income, thus helping remote communities to participate in the clean energy economy of the future and thus overcome some serious social problems. The paper attempts to review current knowledge and provoke debate on relevant investment strategies, and it teases out the questions in need of further research.

Purpose The purpose of this paper is to explore the extent to which consumer purchasing behaviour is influenced by advertised information that a product is made with renewable energy. It also seeks to identify why some consumers might respond more favourably. Design/methodology/approach Three experiments were conducted using two samples of university students enroled in Australia. The first experiment tested the main effect of this research, the second tested the potential amplifying effect of locus of control and the third tested the temporal orientation. Findings Consumer respond favourably to products promoted as made with renewable energy. The possible explanation for this is that future temporal orientation (FTO) influences attitude towards the brand, attitude towards the advertisement, purchase intention and willingness to pay a premium for brands. The observed interaction effect between perceived greenness of the advertisement and FTO is also robust to scepticism. Research limitations/implications Results presented here are also derived from responses made by students at a regional Australian university. Although atypical in their profile with most over 30 years of age, findings cannot reliably be generalised to the larger population. Determining how much importance a renewable energy appeal has when it is positioned among other green appeals would reveal the relative usefulness of the focal promotion to marketers. Practical implications Promoting a firm’s use of renewable energy presents an important opportunity to achieve desirable outcomes, and the efficacy of this is magnified within individuals that habitually focus on the future. Social implications These findings benefit society because they contribute towards increasing the frequency of sustainable business practices. It should also encourage policy-makers to implement policy changes (e.g., removing subsidies that prevent renewable energy from attaining cost parity with non-renewable sources of energy), which can result in beneficial economic outcomes. Originality/value This research is the first of its kind to be conducted in an Australian context, providing findings that assist both firms’ and policy-makers’ decision-making.

The oil and gas reserves of Australia and the East Asian region fall well short of the region's long-term requirements, even for a scenario that phases out all fossil fuels by the end of the 21st century. There is, therefore, no contradiction between vigorous exploration for oil and gas and the process of transition to renewable energy sources. However, to be an independent player in environmental policy-making, the Australian petroleum exploration industry should focus on its particular role within the energy sector as a whole, whose nature will change radically over the next several decades. This role will combine concerns over long term oil supply security with, in particular, the objective of reducing greenhouse gas emissions from oil and gas consumption to levels commensurate with Australia's international obligations. The role extends to Australian involvement in the region as a whole through the accrual of emissions credits from projects implemented jointly with developing countries. It also envisages that Australian explorers, especially those focussed on gas, will form alliances with downstream companies, power generators, appliance manufacturers and energy marketers as links in an integrated chain of operations with value added and emissions reduced at each stage. This re-orientation should lead the industry to question the extent to which its interests correspond with those of the coal and mineral industries, which do not face the same resource limitations.

The aim of the study is to analyze the experience of energy transition management policies in major fossil fuel exporting countries. The change in the structure of the fuel and energy balance in Canada, Australia, Norway, as well as Russia and the EU is assessed. The main trends associated with a significant decrease in the share of coal used and an increase in the share of natural gas and renewable energy sources for all the objects under consideration are identified. The analysis of carbon regulation policy revealed significant differences in the main applied principles. While Australia has a voluntary system of de facto subsidies for low-carbon activities, Canada is dominated by regional mandatory regulation, and Norway uses both tax instruments and EU cap-and-trade system.

Conventional fossil-fuel-based power systems are undergoing rapid transformation via the replacement of coal-fired generation with wind and solar farms. The stochastic and intermittent nature of such renewable sources demands alternative dispatchable technology capable of meeting system stability and reliability needs. Battery energy storage can play a crucial role in enabling the high uptake of wind and solar generation. However, battery life is very sensitive to the way battery energy storage systems (BESS) are operated. In this paper, we propose a framework to analyse battery operation in the Australian National Electricity Market (NEM) electricity spot and contingency reserve markets. We investigate battery operation in different states of Australia under various operating strategies. By considering battery degradation costs within the operating strategy, BESS can generate revenue from the energy market without significantly compromising battery life. Participating in contingency markets, batteries can substantially increase their revenue with almost no impact on battery health. Finally, when battery systems are introduced into highly volatile markets (such as South Australia) more aggressive cycling of batteries leads to accelerated battery aging, which may be justified by increased revenue. The findings also suggest that with falling replacement costs, the operation of battery energy systems can be adjusted, increasing immediate revenues and moving the battery end-of-life conditions closer.

The previous decade has witnessed an unprecedented increase in societal appreciation for the existence of climate change and its associated impacts. One need only look to the reports of the Intergovernmental Panel on Climate Change (IPCC) for evidence—between 1990 and 2007, scientific acceptance of the anthropogenic nature of climate change has risen from merely perhaps in 1990 to a certainty of 90% in 2007. As governments look to create imposts on the very emissions causing climate change, be it through emissions trading schemes (ETS) or through carbon taxes, an equally stark appreciation has occurred in relation to the need to switch to low emissions fuel source in the absence of carbon capture and storage. In contrast to the introduction of the EU ETS, fuel switching in Australia will be more problematic—now Australia sources only a small fraction of its energy supply from renewable energy sources and it will take some time for this to change. What is therefore needed, is a transition fuel—a fuel that will provide Australia with a stepping stone to a sustainable future while at the same time ensuring the security of our energy supply. Coal seam gas (CSG) could play an important part in this progression. Its role is not, however, without its complexities. In a world of daily regulatory and market developments, the CSG industry will need to incorporate both Australian and international climate change issues into its development plans - its physical, reputational, regulatory and market risks and opportunities. This extended abstract will examine the links between these exposures and the future growth potential of the industry.

Determining the lifetime of solar photovoltaic modules is integral to planning future installations and ensuring effective end-of-life management. The lifetime of photovoltaic modules is most commonly considered to be 25 years based on performance guarantees of 80% power output after 25 years of operation; however, influences including climatic conditions, social behaviour, fiscal policy, and technological improvements have the potential to prompt early replacement. Therefore, this work aims to estimate the operating lifetime of photovoltaic panels more accurately in Australia by considering a variety of technical, economic, and social reasons for decommissioning. Based on a range of sources including government organisations, other policymakers, regulators and advisors, energy suppliers, researchers, recyclers, and manufacturers, three lifetime models—power decrease, damage and technical failures, and economic motivation—were developed and then weighted in three scenarios to form overall views of panel lifetime in Australia. In addition, it was concluded that the module lifetime will vary considerably between countries due to differences in market factors. Therefore, these results specifically address Australia as most of the input data were sourced from Australian industry reports and Australian photovoltaic systems and interpreted within the context of the Australian photovoltaic market. However, the methodology of estimating lifetime based on both technical and non-technical factors can be applied to other scenarios by using country-specific data. With the popularity of photovoltaic technology beginning in the early 2010s and given the practical lifetimes of 15–20 years found in this work, Australia will need to act swiftly within the next three years to responsibly manage the looming solar panel waste.

An eco-friendly and sustainable power production system constitutes the cornerstone of every country’s strategic plan to tackle climate change and enhance energy resource autonomy. Carbon dioxide abatement in electricity generation, in addition to being a necessary condition for t “green” energy transition, can contribute greatly to cleaner industrial production and sustainable development. Emphasizing this key role of the power sector, the present research focuses on shedding light on the impact of renewable energy resources (RES), per capita gross domestic product (GDP), electricity gross fixed capital formation (GFCF) and urbanization in the CO2 intensity, and the sustainability level of electricity production. The analysis is based on a comprehensive dataset of 31 countries including 26 European countries, U.S.A., Japan, Australia, Canada, and New Zealand from 1995 until 2018. The econometric outcomes revealed the strong statistical significance of all variables and a plethora of causality relationships, upon which several policy suggestions are made. Interestingly, GDP per capita beyond a certain level can gradually become an aggravating factor for the electricity carbon footprint. Similarly, the vital role of RES in clean electricity production was confirmed as expected, yet surprisingly, this effect also appears to reverse after a certain percentage of total RES reliance. In contrast to urbanization, the electricity GFCF parameter is estimated to have an adverse effect on electricity CO2 intensity, indicating that the vast amount of new investments in the power sector concerns carbon-intensive technologies. Finally, a dynamic analysis is carried out, revealing to policy makers the necessary time frame after which the implementation of new energy policies can have the full impact on the carbon emissions of electricity generation.

Accurately forecasting the output of grid connected wind and solar systems is critical to increasing the overall penetration of renewables on the electrical network. This is especially the case in Australia, where there has been a massive increase in solar and wind farms in the last 15 years, as well as in roof top solar, both domestic and commercial. For example, in 2020, 27% of the electricity in Australia was from renewable sources, and in South Australia almost 60% was from wind and solar. In the literature, there has been extensive research reported on solar and wind resource, entailing both point and interval forecasts, but there has been much less focus on the forecasting of output from wind and solar systems. In this review, we canvass both what has been reported and also what gaps remain. In the case of the latter topic, there are numerous aspects that are not well dealt with in the literature. We have added discussion on the value of forecasts, rather than just focusing on forecast skill. Further, we present a section on how to deal with conditionally changing variance, a topic that has little focus in the literature. One other topic may be particularly important in Australia at the moment, but may become more widespread. This is how to deal with the concept of a clear sky output from a solar farm when the field is oversized compared to the inverter capacity, resulting in a plateau for the output.

PurposeAs the impacts of climate change become more evident, the need to adopt new ways of constructing buildings becomes more urgent. The Earth has experienced hotter climates globally for the last 70 years (NASA, 2019), and this has resulted in unprecedented levels of bushfire in Australia, flooding in the UK and drought in Africa in early 2020 (World Resources Institute, 2019). The predictions are for increased temperatures globally and increasing carbon emissions from fossil fuel consumption. There is a critical need to reduce the reliance on fossil fuels as a building energy source (WCED, 1987). Existing renewables focus on solar, wind and wave power, where technological improvements have increased efficiencies (Hinnells, 2008). Uptake of the technologies is variable depending on location and willingness to adopt renewables. As well as further uptake of existing renewable energy sources, we need to look wider and across traditional discipline groups, at new technologies such as biotechnologies. One potential energy source is biofuels. Biofuels are produced from biomass, which is algae. In 2016, the BIQ, a four-storey apartment building, was constructed in Hamburg, Germany. The BIQ features glazed façade panels filled with algae to produce biomass and solar thermal energy. Could algae building technology (ABT), in the form of façade panels, offer a new renewable energy source?Design/methodology/approachWhat are the technical issues associated with Algae building technology? This qualitative research sought to identify what technical issues likely to arise in terms of algae building construction, operation and maintenance. Semi-structured interviews with 24 experienced built environment professionals in Australia were undertaken in 2016 to assess the most likely issues that could arise with this new innovative technology.FindingsAs a result, a greater understanding of the range of technical issues related to design, construction, maintenance and operation were identified, as well as the perceived importance of those issues. It was possible to identify the top ten technical issues built environment professionals are concerned about with regard to ABT. The results can inform future designers of ABT.Research limitations/implicationsThis research was restricted to the views of 24 experienced built environment practitioners in Sydney, Australia. None of whom had direct experience of Algae Building Technology. Though knowledgeable, a greater number of interviews may have identified other technical issues.Practical implicationsNo guidelines exist for Algae Building Technology, and this research identifies a comprehensive range of technical issues that need to be considered for the technology to function at optimum levels. As such, this is a starting point for built environment professionals who may be asked to provide professional advice and guidance.Originality/valueTo date, no evaluation of Australian based built environment professionals has been conducted into the technical issues associated with Algae Building Technology.

Australia is experiencing a time of major change in its energy sector. First, there is record investment in developing new fossil fuel resources—such as coal, LNG and coal seam methane gas—for export. Second, there is an ever-increasing attention to renewable energy generation for the domestic market. The looming introduction of a price on carbon (greenhouse gas emissions) in 2012 has fuelled the debate about how clean various energy sources are, and how any/all emissions associated with their development and the generation of energy should be treated. As a market reponse, a significant increase in using life-cycle assessment (LCA) results to communicate environmental performance, particularly about greenhouse gas emissions, have been witnessed. When undertaken appropriately, a full life-cycle approach is the only acceptable methodology to compare disparate technologies or products; however, given the often technical nature of LCA studies, the results are not always conveyed accurately in the non-technical mainstream media. This extended abstract discusses case studies related to the energy sector using LCA results—their benefits and shortcomings—in Australian media; suggestions for better communication and decision making in the coming period are also discussed.

Oil and gas companies are fairly large users of electricity, and the rising cost of electricity has become a major issue for the sector. Oil and gas producers often develop their own gas-fired generation plants and consume their own gas as generation fuel. An increasing price of gas in the domestic market has resulted in a corresponding increase in the opportunity cost of utilising gas for power generation. Declining costs of renewable energy and battery storage open opportunities for oil and gas companies to reduce the consumption of their own gas and source electricity at a lower cost, as well as achieve their sustainability objectives. Gas-fired generation is expected to continue to play a key role in ensuring the reliability of electricity supply. However, the percentage of renewable energy in the supply mix can be increased significantly without compromising the reliability. This paper will focus on the opportunities that exist for oil and gas companies to reduce their overall energy supply costs through a differentiated approach considering renewable energy sources and batteries, competitive tendering of energy supply requirements, and attracting capital from independent power producers and institutional investors. The paper will draw on lessons learnt from other energy intensive businesses in Australia.

The global energy trade is set for its greatest transformation since the 1970s and the rise of OPEC (The Organization of the Petroleum Exporting Countries). Electrification is central to this as countries plough money into renewables to reduce emissions and enhance energy security. But electrification can take the world only so far. With higher carbon prices looming on the horizon, fossil fuel exporters and industrial sectors – as well as heavy-duty trucking, shipping and aviation – need alternatives to decarbonise. Most are looking to electricity-based fuels and feedstocks such as hydrogen, ammonia and methanol to replace hydrocarbons. This will revolutionise energy trade, with total trade declining by as much as 50% and virtually all remaining traded oil gas and coal being either completely decarbonised or backed by offsets. With 147 GWel (giga‐watts electrolyser capacity) in announced projects, green hydrogen produced from renewable electricity is ahead of the game. And while its export supply chains are complex, requiring conversion into a ‘product’ to allow delivery, there is no exploration risk as in oil and gas projects. Worldwide, national hydrogen roadmaps are being passed, with virtually all oil and gas companies, utilities and industrials backing at least one hydrogen project. Focus is now shifting to future sources of hydrogen supply. Lenders will be drawn to locations with a proven track record of exporting natural resources, suitable conditions for low-cost renewable electricity and the potential for large-scale carbon capture. A few countries already stand out, but none more so than Australia. Using our proprietary research, we will present a case study evaluating hydrogen supply options from Australia, Saudi Arabia and Canada – delivered into key markets like Japan for different applications. We will also assess when costs will fall across the value chain – production, midstream and downstream – and reach parity to incumbent fuels.

Electricity that produced by renewable energy sources are countinously increased, but some place in Indonesia have not utilize the renewable sources maximally, for instance Kolorai, South Morotai. Based on data from NASA, solar radiation in kolorai is around 5,99 kWh/m2/day, so solar power plant is one of solution to solve electricity needs in remote area like Kolorai. Futhermore, in solar power plant project, determining the load profile and designing the stand alone PV with simulation is important to make a great system. So the optimal methods are needed to build those system, the methods that have higher energy output, less excess energy, dan have a low Net Present Cost. In this paper, Australian/New Zealand standart and manual calculation are used to create an economical design. The result of the HOMER simulation shows that using Australian/New Zealand standart have a suitable result with excess electricity value is 8,56% and Net Present Cost is 1.439.160.000 rupiah.

The Coronavirus Disease 2019 (COVID-19) is a major virus outbreak of the 21st century. The Australian government and local authorities introduced some drastic strategies and policies to control the outspread of this virus. The policies related to lockdown, quarantine, social distancing, shut down of educational institute, work from home, and international and interstate travel bans significantly affect the lifestyle of citizens and, thus, influence their activity patterns. The transport system is, thus, severely affected due to the COVID-19 related restrictions. This paper analyses how the transport system is impacted because of the policies adopted by the Australian government for the containment of the COVID-19. Three main components of the transport sector are studied. These are air travel, public transport, and freight transport. Various official sources of data such as the official website of the Australian government, Google mobility trends, Apple Mobility trends, and Moovit were consulted along with recently published research articles on COVID-19 and its impacts. The secondary sources of data include databases, web articles, and interviews that were conducted with the stakeholders of transport sectors in Australia to analyse the relationship between COVID-19 prevention measures and the transport system. The results of this study showed reduced demand for transport with the adoption of COVID-19 prevention measures. Declines in revenues in the air, freight, and public transport sectors of the transport industry are also reported. The survey shows that transport sector in Australia is facing a serious financial downfall as the use of public transport has dropped by 80%, a 31.5% drop in revenues earned by International airlines in Australia has been predicted, and a 9.5% reduction in the freight transport by water is expected. The recovery of the transport sector to the pre-pandemic state is only possible with the relaxation of COVID-19 containment policies and financial support by the government.

To facilitate the possible technology and demand changes in a renewable-energy dominated future energy system, an integrated approach that involves Renewable Energy Sources (RES)-based generation, cutting-edge communication strategies, and advanced Demand Side Management (DSM) is essential. A Home Energy Management System (HEMS) with integrated Demand Response (DR) programs is able to perform optimal coordination and scheduling of various smart appliances. This paper develops an advanced DSM framework for microgrids, which encompasses modeling of a microgrid, inclusion of a smart HEMS comprising of smart load monitoring and an intelligent load controller, and finally, incorporation of a DR strategy to reduce peak demand and energy costs. Effectiveness of the proposed framework is assessed through a case study analysis, by investigation of DR opportunities and identification of energy savings for the developed model on a typical summer day in Western Australia. From the case study analysis, it is evident that a maximum amount of 2.95 kWh energy can be shifted to low demand periods, which provides a total daily energy savings of 3%. The total energy cost per day is AU$2.50 and AU$3.49 for a house with and without HEMS, respectively. Finally, maximum possible peak shaving, maximum shiftable energy, and maximum standby power losses and energy cost savings with or without HEMS have been calculated to identify the energy saving opportunities of the proposed strategy for a microgrid of 100 houses with solar, wind, and a back-up diesel generator in the generation side.

The pace of transition to new energy sources, and away from fossil fuels, is as hard to predict as any other impact of climate change. However, it appears inevitable that a transition will be made eventually. In some countries, notably Germany and Denmark, the process is already well underway. In others it is just beginning. This article uses the situation of the state of Victoria in southern Australia to explore the possible extent of landscape change under a move to renewable energy sources, and to explore the key variables and tools for analysis and communication which will identify the consequences and support planning. A scenario for a future level of wind power generation in Victoria is proposed, potential sites identified and then the visual impact of these analyzed, not simply on a case-by-case basis but as a system of facilities across the landscape. People travelling by road, or train, will be particularly aware of the extent to which the change is pervasive and new parameters and representations are proposed for documentation of these dynamic visual landscape outcomes.

Abstract Solar photovoltaic (PV) energy is one of the fastest growing renewable energy sources globally. However, the dependency of PV generation on climatological factors such as the intensity of radiation, temperature, wind speed, cloud cover, etc can impact future power generation capacity. Considering the future large-scale deployment of PV systems, accurate climate information is essential for PV site selection, stable grid regulation, planning and energy output projections. In this study, the long-term changes in the future PV potential are estimated over Australia using regional climate projections for the near-future (2020–2039) and far-future (2060–2079) periods under a high emission scenario that projects 3.4 °C warming by 2100. The effects of projected changes in shortwave downwelling radiation, temperature and wind speed on the future performance of PV systems over Australia is also examined. Results indicate decline in the future PV potential over most of the continent due to reduced insolation and increased temperature. Northern coastal Australia experiences negligible increase in PV potential during the far future period due to increase in radiation and wind speed in that region. On further investigation, we find that the cell temperatures are projected to increase in the future under a high emission scenario (2.5 °C by 2079), resulting in increased degradation and risks of failure. The elevated cell temperatures significantly contribute to cell efficiency losses, that are expected to increase in the future (6–13 d yr−1 for multi-crystalline silicon cells) mostly around Western and central Australia indicating further reductions in PV power generation. Therefore, long-term PV power projections can help understand the variations in future power generation and identify regions where PV systems will be highly susceptible to losses in Australia.

A range of energy sources are used by households across the globe, including electricity, gas, solar, and wood. While there is a large body of international research aimed at understanding household energy use in general, very few studies have focused on the specific topic of residential firewood consumption. In Australia, empirical research to investigate and quantify residential firewood consumption is scarce and outdated, despite the importance of such research for better understanding overall household energy costs and carbon emissions. Unlike other power sources, such as electricity, gas and solar, firewood consumption is not systematically monitored or measured in an objective way, thereby making it difficult to obtain accurate data on the amount of firewood consumed in the residential sector. To address this data gap, the current study used survey data from a sample of 4844 households (including 1168 firewood users) to explore what socio-demographic, dwelling-related and behavioural factors were important for predicting the amount of firewood consumed by Australian households. The results revealed that a range of variables—including geographical location, dwelling type, the number of wood-fired appliances per household, and behavioural factors such as the purpose, timing, frequency, and duration of firewood use—were key determinants of residential firewood consumption in Australia, as self-reported by households. Together, these findings underscore the value of measuring not only geographical and location-based factors in household surveys, but also a range of socio-demographic, dwelling-related, and behavioural variables. By doing so, self-report data collected through surveys is likely to better predict the amount of residential firewood consumption reported (or estimated) by households. Overall, this study makes an important and timely contribution to the literature by demonstrating how social science methods such as household surveys can help improve current estimates of residential firewood consumption used to inform government policy, planning, and decision-making for the future.

ObjectiveIdentify the views of healthcare leaders towards public healthcare’s carbon footprint; the importance or not of healthcare energy supply and sources and; the perceived key barriers for Victorian health care to show leadership on renewable energy sources and supply. MethodsSelf-administered questionnaire (10 Likert scale, two open-ended questions) among 24 Victorian Health Chief Executive Officers (CEOs). Responses were anonymous. Descriptive analysis was conducted. ResultsOverall, 13/24 (54%) of CEOs responded. A majority (11/13) agreed that climate change is causing real and accelerating harm to health and the environment, with impacts on patients, staff and services a current issue. One hundred percent (13/13) saw leadership by the public healthcare sector on environmental sustainability as an important responsibility (strongly agreed, 9/13 (69%); agreed, 4/13 (31%)), with most CEOs supporting their institution increasing the amount of renewable electricity supply over-and-above grid levels (strongly agreed, 3/13 (23%); agreed, 9/13 (69%)). However, support for renewable electricity was, for the most part, aspirational and not perceived as a current priority. The key perceived barriers to increasing renewable electricity supply were Health Purchasing Victoria contract and financial constraints. ConclusionsHealth care itself has a carbon footprint. Public healthcare CEOs are supportive of their institutions increasing use of renewable electricity supply, yet perceived barriers regarding inflexible and poorly transparent purchasing contracts and financial cost exist. What is known about the topic?Australian health care contributes ~7 percent to Australia’s total carbon emissions, with hospital energy consumption (coal-generated electricity and natural/fossil gas) a large majority. An executive level champion is a consistent factor across health services that are taking the lead on environmental sustainability. What does this paper add?Our research is original in understanding the views of Victorian public healthcare CEOs on climate change, renewable energy supply and key barriers to increasing uptake. A majority of public healthcare CEOs see energy choices as an important issue for their patients, staff and institution, and that greater leadership should be shown by health care in light of the urgency required to address greenhouse gas emissions. However, support for renewable electricity was, for the most part, aspirational, with specific barriers identified across the healthcare network. What are the implications for practitioners?This research provides information that can inform a pathway to healthcare decarbonisation via sector-wide action.

Coronavirus Disease 2019 (COVID-19) has affected global economies due to lockdowns, business closures, and travel and other restrictions. To control the spread of the virus, several countries, including Australia, imposed strict border restrictions and lockdown measures. Accordingly, international borders have been closed, and all incoming international passengers are mandated to a 14-day hotel quarantine. Residents’ movements and businesses have been limited to essential services only. Employees have been directed to work from home while businesses moved to a remote working model. Due to such stringent measures, small and medium businesses such as cafes, restaurants, hotels, childcare centers, and tourism-based institutions incurred heavy losses, pushing a considerable portion of such small businesses to close. The airlines, education, tourism, and hospitality sector were the worst impacted among all. Due to such closures and associated effects of COVID-19, the unemployment rates are assumed to be significantly increased in countries like Australia. However, a study investigating this unemployment and reporting its status does not exist for Australia. Therefore, in this study, we investigated the effects of COVID-19 control measures such as travel restriction and lockdown on Australia’s employment status and labor markets. The data for the local transport network, unemployment rates and impacts on the tourism industry in Australia were extracted from the public data sources to assess the unemployment rates at both national and state-wide levels. Further, we also looked into the rehabilitation measures by the Australian government, such as the Job Keeper and Job Seeker programs in March 2020, that aim to provide support to people who are unable to run their businesses or have lost their jobs due to the pandemic. Overall, we observed that despite the global crisis, the Australian unemployment rate has reduced in the last year.

The exhaustion of fossil fuels causes decarbonized industries to be powered by renewable energy sources and, owing to their intermittent nature, it is important to devise an efficient energy storage method. To make them more sustainable, a storage system is required. Modern electricity storage systems are based on different types of chemical batteries, electromechanical devices, and hydrogen power plants. However, the parameters of power plant components vary from one geographical location to another. The idea of the present research is to compare the composition of a solar-powered hydrogen processing closed-cycle power plant among the selected geographical locations (Russia, India, and Australia), assuming the same power consumption conditions, but different insolation conditions, and thus the hydrogen equipment capacity accordingly. The number of solar modules in an array is different, thus the required hydrogen tank capacity is also different. The comparison of equipment requires building an uninterrupted power supply for the selected geographical locations, which shows that the capacity of the equipment components would be significantly different. These numbers may serve as the base for further economic calculations of energy cost.

Nowadays, one of the main pollutant factors is the inefficient use and breakdown of energy technologies. Improving access to modern energy, which emits less pollution, both at home and in the community could benefit the health of many people. Besides, it could contribute to the long-term goals of sustainable development. Health is a universal indicator of progress towards sustainable energy. Given the issue’s relevance, this article examines the impact of energy on public health. The study’s purpose is to substantiate the prospects for achieving sustainable development and human well-being, which depends on the quality of the environment and could be provided by a carbon-free economy. The methodological basis of the work is general scientific research methods, such as empirical and theoretical methods, as well as systemic and functional methods. This study applied VOSviewer tools, Web of Science and Scopus analysis tools, and Google Trends to conduct a bibliometric analysis of the impact of energy factors on public health. Based on Scopus data, the findings confirmed the hypothesis concerning a growing trend of publications examining the impact of energy factors on human health. In the study framework, the VOSviewer 1.6.18 tools allowed the detection of six clusters of research streams: renewable resources, sustainable development, public, energy policy, energy efficiency, and solar energy. The authors noted that different countries research the impact of energy on public health. These issues are most actively studied in China, the USA, and India. A separate dynamics of the publications were studied for 10 countries leading in the publication activity on the subject. The Google Trends tool has identified public interest in the topic. The interest of business and industry is considered separately. The findings showed that in the first case, the interest is more in the health factor. In turn, businesses and industries pay more attention to developing renewable energy sources. Google Trends analysis of the popularity of the search query «renewable energy» identified Korea, Turkey, Nigeria, Bangladesh, and Germany as leaders in the number of queries. However, the keywords healthy leaders are New Zealand, USA, Canada, Poland, and Australia.

Environmental obligation, fuel security, and human health issues have fuelled the search for locally produced sustainable transport fuels as an alternative to liquid petroleum. This study evaluates the sustainability performance of various alternative energy sources, namely, ethanol, electricity, electricity-gasoline hybrid, and hydrogen, for Western Australian road transport using a life cycle sustainability assessment (LCSA) framework. The framework employs 11 triple bottom line (TBL) sustainability indicators and uses threshold values for benchmarking sustainability practices. A number of improvement strategies were devised based on the hotspots once the alternative energy sources failed to meet the sustainability threshold for the determined indicators. The proposed framework effectively addresses the issue of interdependencies between the three pillars of sustainability, which was an inherent weakness of previous frameworks. The results show that the environment-friendly and socially sustainable energy options, namely, ethanol-gasoline blend E55, electricity, electricity-E10 hybrid, and hydrogen, would need around 0.02, 0.14, 0.10, and 0.71 AUD/VKT of financial support, respectively, to be comparable to gasoline. Among the four assessed options, hydrogen shows the best performance for the environmental and social bottom line when renewable electricity is employed for hydrogen production. The economic sustainability of hydrogen fuel is, however, uncertain at this stage due to the high cost of hydrogen fuel cell vehicles (HFCVs). The robustness of the proposed framework warrants its application in a wide range of alternative fuel assessment scenarios locally as well as globally.

AbstractSlovakia is acountry with limited natural resources, therefore its essential task is to search for new renewable sources of energy to reduce its dependence on imported fossil fuels. The results of research confirmed that the Common Reed (Phragmites australis(Cav.) Trin.) has considerable potential of phytomass production and energy storage (calorific value reached 17,448 J g−1d.w.). Biomass production of Common Reed under natural conditions of the lower Liptov region reached 12.702 tons of a dry mater per hectare with the calculated energy storage of 221.622 GJ ha−1. The average biogas production was 351.31 l kg−1of a dry matter of which the methane (CH4) content represents 185.21 l kg−1(52.72%). With regards to the values of combustion heat, a calorific value and the production of methane it can also be noted that in case of Common Reed it is more profitable to focus on direct combustion of biomass than the production of biogas and methane.

Establishing accurate electrical load prediction is vital for pricing and power system management. However, the unpredictable behavior of private and industrial users results in uncertainty in these power systems. Furthermore, the utilization of renewable energy sources, which are often variable in their production rates, also increases the complexity making predictions even more difficult. In this paper an interval type-2 intuitionist fuzzy logic system whose parameters are trained in a hybrid fashion using gravitational search algorithms with the ridge least square algorithm is presented for short-term prediction of electrical loading. Simulation results are provided to compare the performance of the proposed approach with that of state-of-the-art electrical load prediction algorithms for Poland, and five regions of Australia. The simulation results demonstrate the superior performance of the proposed approach over seven different current state-of-the-art prediction algorithms in the literature, namely: SVR, ANN, ELM, EEMD-ELM-GOA, EEMD-ELM-DA, EEMD-ELM-PSO and EEMD-ELM-GWO.

With the COVID-19 outbreak across the world, policymakers and authorities have realised that they cannot solve the emerging issues using conventional policies and practices. COVID-19 has severely affected many industries, including construction and demolition (C&D) waste management and C&D waste resource recovery sector. Extended Producer Responsibility (EPR) and schemes alike are policy instruments that prevent waste generation and promote a circular economy in the construction industry. These schemes are long adopted in various countries for different waste streams. EPR policy development and implementation, particularly for C&D waste, is still at an early stage in Australia. This study aims to review the Australian regulatory environment and practice to identify barriers and enablers towards successful policy development and implementation of C&D waste-related EPR. This study is based on secondary data that are publicly available. The document analysis was conducted to identify the level of regulatory and other stakeholders support in Australia. Following three rounds of examination of sources and applying multiple selection criteria, 59 different sources were reviewed in total. The results showed that there is widespread support among different stakeholders to develop EPR and expand the existing regulation to other materials. The barriers were cost and time implications for EPR policy establishment and enforcement, diversity of stakeholders involved, construction product lifecycle, responsibility of manufacturers, complexity in implantation of EPR regulations, modification inbuilt facilities and health and safety issues. Recommendations are made to alleviate these challenges. The outcome of this study could serve as a guideline for designing effective EPR policies.

With the COVID-19 outbreak across the world, policymakers and authorities have realised that they cannot solve the emerging issues using conventional policies and practices. COVID-19 has severely affected many industries, including construction and demolition (C&D) waste management and C&D waste resource recovery sector. Extended Producer Responsibility (EPR) and schemes alike are policy instruments that prevent waste generation and promote a circular economy in the construction industry. These schemes are long adopted in various countries for different waste streams. EPR policy development and implementation, particularly for C&D waste, is still at an early stage in Australia. This study aims to review the Australian regulatory environment and practice to identify barriers and enablers towards successful policy development and implementation of C&D waste-related EPR. This study is based on secondary data that are publicly available. The document analysis was conducted to identify the level of regulatory and other stakeholders support in Australia. Following three rounds of examination of sources and applying multiple selection criteria, 59 different sources were reviewed in total. The results showed that there is widespread support among different stakeholders to develop EPR and expand the existing regulation to other materials. The barriers were cost and time implications for EPR policy establishment and enforcement, diversity of stakeholders involved, construction product lifecycle, responsibility of manufacturers, complexity in implantation of EPR regulations, modification inbuilt facilities and health and safety issues. Recommendations are made to alleviate these challenges. The outcome of this study could serve as a guideline for designing effective EPR policies.

ABSTRACT Fuel poverty is one of the global concerns affecting not only users' financial capacity or affordability for maintaining housing operation but also the occupants' health and wellbeing. Space heating and cooling require a relatively large amount of domestic energy use in housing. Therefore, this study was formed with the aim to propose an innovative approach to utilising free, clean renewable sources of energy applicable to the space heating and cooling of housing in both cold and hot regions. Accordingly, housing test facilities based in Melbourne, Australia, and Kuching, Malaysia, were selected and used for this study that examined the thermal performance of a proposed ‘hydronic radiator’ (HR) system through simulation and onsite measurements. The geothermal heat capacity of a ‘vertical ground heat exchanger’ (VGHE) installed in the house in Melbourne was examined previously by the authors and the VGHE measured data was also applied to this HR performance simulation. The water that circulates through the HRs is heated by sunlight and VGHE or cooled by night sky radiation. This study drew conclusions that the sole utilisation of renewable sources through these proposed HR space heating and cooling systems can provide thermally accessible or comfortable indoor living environments in both heating or cooling dominant regions. Thus, fuel poverty issues may be alleviated through HR system application. The HRs can remove a ‘sensible’ portion of metabolic heat, but they cannot effectively contribute to the ‘latent’ heat removal. Thus, the future potential use or effect of ‘flow-through’ HRs, which are integrated into a underfloor air distribution (UFAD) plenum, was also dsicussed in this study. In the test house located in Melbourne, the flow-through HR UFAD system is currently under development. Therefore, the performance will be measured once the system has come into operation for further testing.

Despite the route lined out since the turn of the 21st century toward the use of renewable energy sources, as of today and for the nearest decades, the fossil energy resources represent the critical part in the world economy. Fossil fuels will keep prevailing in the energy budget of the most countries in 2020 according to the long-term forecasts of the International Energy Agency and by estimates of the other authoritative sources. In the electric energy production, the contribution of coal in 2020 is the largest worldwide and continues growing owing to high-level consumptions in China, India, developing countries in Southeastern Asia, as well as in the mature economies of Japan and Australia. The huge own reserves of coal provide the developing economies with relatively cheap and reliable source of energy, the underside of which is the increased environmental damage. It is critical to develop and investigate approaches to minimization of technological environmental impact at the preserved balance between the economic advance, social welfare and environmental conservation. In the coal-powered energy generation, such approach is application of clean mining technologies. In order to identify application features of such technologies in modern conditions and in the future, it is necessary to review the historical background of economically efficient solutions, the engineering capabilities and the global market conditions in terms of the United States of America as the top coal producer and consumer among the mature economies possessing the advanced coal mining technologies. The outcome of the review is also helpful in the analysis of economic efficiency of clean technologies to be introduced in the coal industry in Russia. Thus, the aim of this article is to examine development and introduction of clean coal technologies in terms of the U.S.A. for tracing promising trends in the conditions of a global economic system.

In recent years, the number of court cases around theworld raising the issue of climate change has increased dramatically, especially in jurisdictions that have not yet adopted effective national responses to climate change, such as Australia and the United States. In these countries, litigation provides an alternative path to encourage mitigation of the causes and adaptation to the effects of climate change. In Australia, much of the litigation, particularly the early climate change cases, has taken place in state courts or administrative tribunals, and has focused on applying existing legislation to require government decision-makers to consider future climate-associated risks in planning decisions. The influence of these cases have been wide reaching, leading to the revision or formulation of government policies on mining and coastal management. Other cases, particularly within federal courts, have been less successful, but have nonetheless highlighted areas in need of law reform. In the United States, recent high-profile cases targeting major sources of greenhouse gas emissions including power stations have raised novel arguments based on common law public nuisance grounds and the public trust doctrine. This article examines the extent to which climate change litigation, mainly in Australia, but also in the United States, has influenced government decision-makers, legislatures, and polluters to curb emissions and adapt to the impacts of climate change.

Abstract The energy landscape in Australian built environment is becoming more complex, with traditional utility consumption declines and the rise of renewable energy sources, meaning buildings are able to generate, monitor and store their own energy. These energy transitions are impacting upon the stability of traditional business models. Energy-as-a-service (EaaS) as an emerging business model has shown potential under this complex energy transition. However, with limited studies into this business model, there is a research gap in understanding of how EaaS can facilitate a successful energy transition. In addressing such research gap, this study investigates about potential pathways to establish EaaS from an industry perspective. A generic qualitative research design within a constructivist paradigm was adopted in this exploratory study with twenty-nine semi-structured interviews. The study revealed four recommended directions EaaS could be practically established for improving energy transition within the built environment. This study contributes by providing research-based evidence into new, emerging, and innovative business models within the built environment.

Abstract The energy transition entails a rapid uptake of renewable energy sources. Besides physical changes within the grid infrastructure, energy storage devices and their smart operation are key measures to master the resulting challenges like, e. g., a highly fluctuating power generation. For the latter, optimization based control has demonstrated its potential on a microgrid level. However, if a network of coupled microgrids is considered, iterative optimization schemes including several communication rounds are typically used. Here, we propose to replace the optimization on the microgrid level by using surrogate models either derived from radial basis functions or neural networks to avoid this iterative procedure. We prove well-posedness of our approach and demonstrate its efficiency by numerical simulations based on real data provided by an Australian grid operator.

Chinese inbound tourism growth peaked in 2012 and in following years, arrivals have exhibited a downward trend. Over the same time Chinese outbound tourism has increased significantly and by 2016 the number of Chinese outbound tourists (52.7 million) was nearly twice that of international arrivals to China (28.1 million) (CTA, 2018). The aim of this paper is to identify the determinants of international tourists visiting China based on destination attributes. For the purposes of this research, Australia was selected as a study site on the grounds that China has been a popular destination for Australian residents. This study examines a range of behavioral factors that may affect intentions to travel to China including: past travel experience to China; perceptions of overseas destination attributes; beliefs in China’s ability to satisfy the needs and constraints that appear to prevent Australian residents from traveling to China; and tourists’ intentions to visit or revisit. Data collected from Australian residents on aspects of travel to China included perceptions, beliefs, constraints, information sources, and past experience. The research shows that past experience was positively associated with intention to visit or revisit. Five constraint factors were identified. Based on these findings, the study discusses practical implications for management and government officials needed to boost Chinese inbound tourism.

Today’s energy and resources companies must address many challenges to their traditional business models including the rapid emergence of available and economic renewable energy sources, ever tightening greenhouse gas emission policies and increased stakeholder expectations around transparency. While there is uncertainty regarding the impact of these developments, enormous opportunity exists for companies to forge pathways to a decarbonised future while at the same time creating new markets, products and services and increasing revenues. Several leading Australian resources companies have recently embarked on programs to transition to a lower carbon and more diversified energy portfolio. These initiatives focus on integrating alternative forms of energy across value chains, making energy consumers central to their business models and increasing energy security for their companies and the country. This paper discusses the drivers underlying these challenges, draws on case studies of how oil and gas companies are managing their journey, considers the impact such programs on the companies’ financial and operational performance and outline some implications and possible approaches.

Deep-water dogfish (sharks) are caught on Australia’s continental shelf as by-products to other deep-water species with revenue derived from fillets for human consumption and from the livers which are sold for their oil content. Deep-water dogfish utilise a large oil-rich liver for buoyancy, which may account for 20–25% of their body weight. An important constituent of certain dogfish liver oil is squalene, a highly unsaturated triterpenoid (C30H50) hydrocarbon which in some species can be up to 90% of the oil, though in the Australian commercial species it is typically around 50%. Squalene (and deep-water dogfish liver oil in general) has a long-standing high value in products, such as cosmetics and nutraceuticals. Manufacturers are increasingly required to demonstrate the sustainability of products, and this is integral to the importance of demonstrating product provenance. Australia’s mid-slope deep-water dogfish fishery is recognised globally as well managed and sustainable; therefore, it is important to be able to distinguish products derived from these regions from other unregulated, unsustainable and cheaper sources in order to protect Australia’s competitive advantages and ensure sustainability. In this study, we have sourced deep-water dogfish liver oil samples originating from Southeast Australia, New Zealand, India, Northeast Africa and the Arabian Sea. The squalene was isolated by commercial or laboratory processing. A compound-specific carbon stable isotope analysis of the derived squalene was then used to determine isotopic resolution and assign the likely origins of a variety of commonly available off-the-shelf nutraceuticals in Australian outlets. Squalene sourced and produced from Southeast Australian and New Zealand dogfish liver oils showed δ13C values in the range of −22.1 to −24.2‰, with all other squalene samples distinguishable at −19.9 to −20.7‰. Many of the off-the-shelf squalene products claiming to be of Australian origin showed δ13C values very distinct from the range of the genuine Southeast Australian- and New Zealand-produced squalene.
