The history of ocean renewable energy developments in Australia is reviewed. A layperson’s description of the physical operating principle is given for the main classes of technology that have been tested in Australian waters. The Australian marine domain possesses among the world’s most energetic wave-energy resources, driven by powerful mid-latitude westerly winds. The northern coast of Western Australia has tidal ranges significant on a global scale, and some geographical features around the continent have local tidal resonances. The East Australian Current, one of the world’s major western boundary currents, runs along the eastern Australian seaboard, offering potential for ocean-current energy. Sea-water temperatures in the tropical north-east of Australia may permit ocean thermal energy conversion. While this abundance of resources makes Australia an ideal location for technology development, the population is highly concentrated in a few large cities, and transmission infrastructure has developed over a century to supply cities from traditional power plants. Several wave-power developments have resulted in demonstration of deployments in Australian waters, three of which have been grid connected. Trials of tidal devices have also occurred, while other classes of ocean renewable energy have not yet been trialled. The prospects for marine renewable energy in Australia are discussed including non-traditional applications such as coastal protection and energy export.

In 2016, sustained depressed and volatile oil prices led companies to continue cost reduction strategies. Proposed developments have seen delays and reductions in scope as a result. Australian oil production declined by around 10%. However, new and continued liquefied natural gas (LNG) production bolstered both Australian and global gas supply. Australia was the strongest contributor to global LNG growth in 2016, showing the biggest year-on-year increase. In the first half of 2016, 20% of global LNG came from Australia, second only to Qatar with 29% of the market share. Australia remains on track to become the world’s largest LNG producer in the next 3–5 years. 2016 saw the start-up of Gorgon LNG in March, the first of Chevron’s two North West Shelf LNG projects and the third of several producing, developing and proposed LNG projects within the North Carnarvon Basin – already Australia’s most prolific producing basin. On the east coast, development of the coalbed methane (CBM) to LNG projects continued with an additional train brought onstream at each of the Origin/ConocoPhillips-operated APLNG Project and Santos’ GLNG Project. This further increased production in the Bowen–Surat Basins and drove discussions around the ability of east coast gas to meet both the demands of the LNG projects and ensure continued domestic gas reliability. Additional gas may be required for both, opening opportunities for production from other basins. Gas production continues to drive the Australian industry, with substantial inputs from LNG and unconventional operations. The next phase, in all sectors, will be key to Australia’s future in the global energy market. Will it be able to overcome the expected challenges of global oversupply, continued price volatility and domestic reliability concerns to fulfil its potential?

This Petroleum Exploration Society of Australia review looks in detail at the trends and highlights for oil and gas production and development both onshore and offshore Australia during 2017. Gas production soared while oil production plummeted yet again. Liquefied natural gas (LNG) did well; 2017 was a great year for LNG and 2018 should be even better. There are stark contrasts between domestic gas on the west and east coasts. On the west coast, prices are affordable and supply relatively plentiful. On the east, prices are high and gas is in short supply. This paper canvasses these trends and makes conclusions about the condition of the oil and gas industry in Australia. This paper relies primarily on production and reserves data compiled by EnergyQuest. In its latest review of Australian energy policy, the International Energy Agency comments yet again on the weaknesses of Australian oil and gas statistics. This paper also makes some observations on these weaknesses.

This Petroleum Exploration Society of Australia review looks in detail at the trends and highlights for oil and gas production and development both onshore and offshore Australia during 2018. Total petroleum production climbed strongly for the third consecutive year, driven by LNG. A highlight is the start-up of the INPEX Ichthys project. Production is set for further growth in 2019 with the ramp-up of this project and the start-up of Shell’s Prelude floating LNG project. Prelude and Ichthys are the last projects to be commissioned in a wave of seven new LNG projects that are making Australia the world’s largest LNG exporter and a crucial supplier of gas to Asia, including the largest source of LNG for Japan and China and the second-largest source for South Korea. By contrast, Australian oil production continued to fall rapidly and is now easily surpassed by rising condensate production from new LNG projects. There were stark contrasts between domestic gas on the west and east coasts. On the west coast, prices remain low and supply relatively plentiful. The east coast domestic market was tighter and LNG producers responded by diverting gas supplies to the domestic market. This paper canvasses these trends and makes conclusions about the condition of the oil and gas industry in Australia. This paper relies primarily on production and reserves data compiled by EnergyQuest and published in its EnergyQuarterly reports.

The development of a complex and dynamic system such as the energy sector requires a comprehensive understanding of its constituent components and their interactions, and thus requires approaches that can adapt to the dynamic complexity in systems. Previous efforts mainly used reductionist approaches, which examine the components of the system in isolation, neglecting their interdependent nature. Such approaches reduce our ability to understand the system and/or mitigate undesirable outcomes. We adopt a system dynamics approach to construct an integrated model for analysing the behaviour of the energy sector. Although the Australian energy sector is used as a case study, the model can be applied in other context elsewhere around the world The results indicate that the current trajectory of the Australian energy sector is unsustainable and growth is not being controlled. Limits to growth are fast approaching due to excessive fossil fuel extraction, high emissions and high energy dependency. With the current growth, Australia’s global CO2 emissions footprint will increase to unprecedented levels reaching 12% by 2030 (9.5% for exports and 2.5% for domestic). Oil dependency will account for 43% and 47% of total consumption by 2030 and 2050. By 2032, coal will be the only fossil fuel resource available in Australia. Expansion of investment in coal and gas production is a large risk.

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.

In recent years the media has published articles relating to the high cost of doing business in Australia. The impacts of low productivity, high-labour costs, and poor performance have all been highlighted as ailments with Australia and within the LNG (construction) industry in particular. This has led to views that Australia is a high-cost environment and Australian LNG is expensive. The numbers that are often quoted appear to support these views, however they overlook—and sometimes mask—aspects of individual projects that are important to understand before making any generic pronouncements about the competitiveness of the Australian industry in general. This extended abstract: Exposes the inadequacies of the general comparisons that have been made in the recent past. Demonstrates the actual impact of several identified issues. Demonstrates the importance of decisions made early in the project development cycle by respective owners on the projects and project costs. Identifies the differences and similarities in development and costs of LNG projects in Australia compared to other areas of the world, in particular the US. Examines the impact of lack of collaboration.

2011 was a lacklustre year for Australian hydrocarbon production, however a stellar year for LNG development. Domestic gas production was flat despite two new gas developments, Reindeer/Devil Creek and Halyard/Spar, which came into production during the year. Oil production fell, primarily due to the redevelopment of North West Shelf oil facilities, with Kitan in the Timor Sea being the only new offshore oil field that commenced production. LNG production was also flat however, Final Investment Decisions (FID) were announced for five new LNG projects, including Ichthys early in 2012, bringing the combined value of all eight sanctioned LNG projects to more than $180 billion. This is a huge volume of development, not only for the industry but for the whole Australian economy. Importantly, it has also moved Australia closer to becoming the world’s largest LNG producer. Increasing development costs and competition for skilled labour still remain the biggest challenges for the industry. Introduction of the carbon tax was also an important development in 2011, marking a significant step towards a low-carbon economy and increasing the opportunity for natural gas, but also burdening trade-exposed industries like LNG. The success of unconventional gas in the United States and CSG in Australia has sparked a step-change in exploration and development of unconventional gas in onshore Australia. Consolidation in coal seam gas sector continued on the east coast with the two acquisitions of Eastern Star Gas by Santos and Bow Energy by Arrow Energy. Continuing to effectively engage with the community will be central to the industry’s success.

2010 was another busy year for Australian hydrocarbon production and development. Natural gas production was the standout performer with both domestic gas and LNG production increasing by about 5% compared to 2009. Domestic gas output was strong with significant growth in production from the Gippsland Basin, coal seam methane in the Surat-Bowen Basin, and the start-up of the Blacktip gas project in WA. Domestic gas output is set to reach record levels again next year and has strong growth prospects in the future with final investment decisions being taken on coal seam gas projects in Queensland and the Macedon project in WA. Australian LNG production increased 4.5% in 2010 accounting for 34% of Australian hydrocarbon production. LNG production will grow further in 2011 with first gas expected from Pluto LNG project during the year. Oil production was steady in 2010; however, it is set to increase in 2011 with a full year of production from the Van Gogh and Pyrenees projects. Production levels only tell part of the Australian hydrocarbon story. In addition to the proposed domestic gas and oil projects, the combined value of committed and potential LNG projects in Australia has surpassed $100 billion. A highlight of 2010 was the final investment decision on the A$15 bn Queensland Curtis LNG Project (QCLNG). The first phase of QCLNG will consist of two LNG trains with a combined capacity of 8.5 million tonnes per annum, with first LNG exports expected in 2014. QCLNG is the first of many proposed coal seam gas to LNG (CSG-LNG) developments in Queensland. Other CSG-LNG projects reached significant milestones this year. Of particular note is the federal environmental approval of Gladstone LNG and state environmental approval of Australia Pacific LNG. In WA, the Browse LNG project complied with all Browse Basin retention lease conditions and remains on track for a targeted final investment decision in 2012. Other major LNG projects including Ichthys and Wheatstone also continue to make positive progress towards a final investment decision in the next 24 months. Sunrise, Prelude and Bonaparte LNG set a technology milestone in the industry with all three selecting floating LNG (FLNG) as their preferred development concept. 2010 has also seen the emergence of further new technologies in the form of small scale LNG projects for resources previously considered un-commercial. This has opened the door for South Australia and New South Wales to enter the LNG export market in the future. The Australian hydrocarbon industry continues to grow and its global importance, particularly in LNG, reflected by the increasing number of foreign companies entering Australia. In 2010, Shell and PetroChina increased their involvement in the Australian industry purchasing Arrow Energy for A$3.5 bn. CNOOC has increased its involvement in a number of areas, including purchasing a 5–10% stake in QCLNG and investment in CSM exploration through Exoma Energy. GDF Suez and Total have reinvigorated their interests in offshore WA and Petrobras made their first entry into Australia acquiring an interest in exploration acreage offshore WA. 2010 was an active year for Australian hydrocarbon production and development–continued success depends on the successful execution of committed and proposed projects. Escalation of development costs and a looming skills shortage remain the largest risks to the Australian hydrocarbon industry as multiple projects attempt to move forward simultaneously.

Australia will increasingly need to turn to natural gas to offset declining oil production and meet an expanding global need for clean energy. The Gorgon Development Joint Venture Participants, (ChevronTexaco/Exxon- Mobil/Shell), are poised to develop the significant Gorgon gas reserves located 130 km offshore the North West Australian coast to help fulfil this need.The Gorgon Development has access to extensive proved reserves of 13.8 Tcf and a development plan that can supply gas to a Barrow Island landfall at world competitive prices. Several concepts are being considered for development of the Gorgon reserves.Technology will play a key role, with the extensive use of subsea production facilities and innovative LNG design concepts being considered.The focus is on a design that would have a low unit cost and also provide new benchmarks in safety and environmental performance. The development of the Gorgon reserves could also facilitate the establishment of other gas-based industries in Western Australia and offers the opportunity for new gas-to-liquid (GTL) plants to lead Australia’s transition to a gas-based economy.The Gorgon Development is expected to attract nearly A$4 billion investment for an LNG development and a further A$2 billion for a major industrial gas consumer. Total export income could reach A$2,500 million per year for 30 years.

In order to consolidate a sustainable renewable energy infrastructure, the Australian state of Victoria requires an advancement and development of any feasible renewable energy alternatives. There is a large onshore wind energy market in Victoria but the state currently has no offshore wind technology under consideration or proposal. Australia, and Victoria, has a vast coast line with desirable wind resources for offshore wind implementation. In order to definitively investigate the potential for such technology, a simulation was designed to test the amount of power that could be produced in Victoria by using real life wind speed data sets. The simulation output was analyzed in conjunction with an analysis of the social, political, environmental and economic considerations that could increase or decrease the potential for this technology. 11 simulation scenarios were tested and analyzed, two of which produced a positive net present value by the conclusion of its commissioned operational life. It was found that there is the potential for development of this technology within certain locations in Victoria but it would face several barriers to implementation. The most prominent barriers are competition with a thriving coal and fossil energy industry and competition with more economically desirable alternative renewable technologies such as onshore wind energy.

Background: ISO 50001 is the international standard for Energy Management Systems (EnMS), following the same Plan-Do-Check-Act framework as other highly successful ISO standards such as ISO 14001 Environmental Management and ISO 9001 Quality. The opportunity for efficient integration with these standards along with the well understood and academically agreed benefits for emissions reduction and cost savings have facilitated a growth in ISO 50001 implementation. Previous literature has identified that this implementation has predominantly occurred in the energy intensive industry sectors such as manufacturing. An ‘efficiency gap’ or ‘energy paradox’ has been identified to be hindering the implementation of compliant EnMSs, particularly in the service and commercial sectors.
Purpose: The aim of this study is to identify the influencing factors; barriers, motivators, opportunities, and enablers which may influence the implementation of ISO 50001 in the service sector, such as that of a Western Australian (WA) Local Government (LG).
Methods: The researcher was embedded within the City of Melville (CoM) LG in which a literature synthesis, document review and case study observations were collected. The literature synthesis was conducted to provide a theoretical underpinning of the potential influencing factors of ISO 50001 implementation within a LG. The literature included ISO 50001 case studies from several energy intensive disciplines and other sustainable energy initiatives more commonly implemented beyond the industry sector. In parallel the CoM document analysis and case study observations were conducted weekly over the duration of the work experience.
Results: The literature synthesis identified the key theoretical barriers as Resources, System Structure, Information and Behaviour of stakeholders. Several key positive influencing factors were also identified to potentially alleviate the effects or overcome these barriers. The overarching positive influencing factors included the WA institutional values and context, Top Management Support and Additional Grant Funding. When these were considered individually as drivers or enablers the additional positive influencing aspects are Emission Reduction and Public Interest (Drivers) and existing ISO Certifications, Staff Support and External Relationships (Enablers). Based on these results the two key barriers that are specific for a LG were System/Structure and Time Resources. However, the key influencing factor that could override these barriers is the established External Relationships that provide the technical capacity not typically available within LGs. In the CoM context the Addition of Funding was observed to have significant benefits to enabling ISO 50001 implementation.
Conclusions: The results discussed were unique to the LG context with the influencing factors of Time Resources and External Relationships for capacity building as findings unique within the case study. This is a foundational study which is recommended to be built upon to increase the understanding of both the qualitative and quantitative results of an ISO 50001 compliant EnMS in the LG context. With increased awareness in these outcomes, it is concluded that the benefits of the ISO 50001 standard can reach beyond the industrial sector and into the LG context.

Barriers to renewable energy development in the past have been identified as high upfront costs with challenges around equity and debt financing, as well as limited legal frameworks and limited regulatory support. Although it is noted that barriers to development are country specific, as well as the solutions to overcome such barriers. Policy measures implemented in various countries to support renewable energy have been seen to have a marked impact on its development. The renewable energy industry in Australia is showing unprecedented growth with a drastic change in the energy landscape expected in the future, should all proposed developments come to fruition. Renewable energy in Australia is currently in its infancy though. It is expected that the planned integration of all the proposed developments in the National Electricity Market will result in certain barriers to development emerging at higher levels of integration. Australia's energy policy has taken significant steps to supporting the deployment of cleaner generation technologies, although hurdles at federal and state level have in the past frustrated the development of renewable energy. The history and status quo of renewable energy development in Australia has been investigated. The current framework and support structures in place as well as potential barriers have been reviewed. A qualitative investigation utilising a single case study approach was selected as the research method. The case investigated was the renewable energy division of a leading global engineering consultancy operating in Australia. The participants of the study included the senior management staff in the renewable energy division of the company. Standard open-ended interviews were conducted. The data was analysed by employing a method of pattern matching. The observed data from the interview process was analysed and compared against the expected pattern which had emerged from the literature. Potential barriers and support strategies have been outlined as a conclusion to the study. The study found federal energy policy to be favourable, but not vital for continued growth of RE development. It was acknowledged that a focus on grid infrastructure would be vital to avoid constricting asset development. The development of Renewable Energy Zones was considered a favourable strategy to overcoming barriers identified, although it was noted that community acceptance would be a significant consideration. Gas generation may form part of the future energy mix, but will be dependent on price and emergent technology. Pumped hydro power is expected to be an important compliment to renewable energy in future, to assist in addressing the technical barriers associated with high levels of non-synchronous generation in the network. A reform of the NEM may also be required to cater for a scenario of a significant penetration of renewable energy and is a topic recommended for future research.

Mallee biomass is considered to be a second-generation renewable feedstock in Australia and will play an important role in bioenergy development in Australia. Its production is of large-scale, low cost, small carbon footprint and high energy efficiency. However, biomass as a direct fuel is widely dispersed, bulky, fibrous and of high moisture content and low energy density. High logistic cost, poor grindability and mismatch of fuel property with coal are some of the key issues that impede biomass utilisation for power generation. Therefore, innovations are in urgent need to improve biomass volumetric energy densification, grindability and good fuel matching if co-fired with coal. Biomass pyrolysis is a flexible and low-cost approach that can be deployed for this purpose. Via pyrolysis, the bulky biomass can be converted to biomass-derived high-energy-density fuels such as biochar and/or bio-oil. So far there has been a lack of fundamental understanding of mallee biomass pyrolysis and properties of the fuel products.The series of study in this PhD thesis aims to investigate the production of such high-energy- density fuels obtained from mallee pyrolysis and to obtain some new knowledge on properties of the resultant fuels and their implications to practical applications. Particularly, the research has been designed and carried out to use pyrolysis as a pretreatment technology for the production of biochar, bio-oil and bioslurry fuels. The main outcomes of this study are summarised as follows.Firstly, biochars were produced from the pyrolysis of centimetre-sized particles of mallee wood at 300-500°C using a fixed-bed reactor under slow-heating conditions. The data show that at pyrolysis temperatures > 320°C, biochar as a fuel has similar fuel H/C and O/C ratios compared to Collie coal which is the only coal being mined in WA. Converting biomass to biochar leads to a substantial increase in fuel mass energy density from ~10 GJ/tonne of green biomass to ~28 GJ/tonne of biochars prepared from pyrolysis at 320°C, in comparison to 26 GJ/tonne for Collie coal. However, there is little improvement in fuel volumetric energy density, which is still around 7-9 GJ/m[superscript]3 in comparison to 17 GJ/m[superscript]3 of Collie coal. Biochars are still bulky and grinding is required for volumetric energy densification. Biochar grindability experiments have shown that the fuel grindability increases drastically even at pyrolysis temperature as low as 300°C. Further increase in pyrolysis temperature to 500°C leads to only small increase in biochar grindability. Under the grinding conditions, a significant size reduction (34-66 % cumulative volumetric size <75 μm) of biochars can be achieved within 4 minutes grinding (in comparison to only 19% for biomass after 15 minutes grinding), leading to a significant increase in volumetric energy density (e.g. from ~8 to ~19 GJ/m[superscript]3 for biochar prepared from pyrolysis at 400°C). Whereas grinding raw biomass typically result in large and fibrous particles, grinding biochar produce short and round particles highly favourable for fuel applications.Secondly, it is found that the pyrolysis of different biomass components produced biochars with distinct characteristics, largely because of the differences in the biological structure of these components. Leaf biochars showed the poorest grindability due to the presence of abundant tough oil glands in leaf. Even for the biochar prepared from the pyrolysis of leaf at 800°C, the oil gland enclosures remained largely intact after grinding. Biochars produced from leaf, bark and wood components also have significant differences in ash properties. Even with low ash content, wood biochars have low Si/K and Ca/K ratios, suggesting these biochars may have a high slagging propensity in comparison to bark and leaf biochars.Thirdly, bio-oil and biochar were also produced from pyrolysis of micron-size wood particle using a fluidised-bed reactor system under fast-heating conditions. The excellent grindability of biochar had enabled desirable particle size reduction of biochar into fine particles which can be suspended into bio-oil for the preparation of bioslurry fuels. The data have demonstrated that bioslurry fuels have desired fuel and rheological characteristics that met the requirements for combustion and gasification applications. Depending on biochar loading, the volumetric energy density of bioslurry is up to 23.2 GJ/m[superscript]3, achieving a significant energy densification (by a factor > 4) in comparison to green wood chips. Bioslurry fuels with high biochar concentrations (11-20 wt%) showed non-Newtonian characteristics with pseudoplastic behaviour. The flow behaviour index, n decreases with the increasing of biochar concentration. Bioslurry with higher biochar concentrations has also demonstrated thixotropic behaviour. The bioslurry fuels also have low viscosity (<453 mPa.s) and are pumpable at both room and elevated temperatures. The concentrations of Ca, K, N and S in bioslurry are below the limits of slurry fuel guidelines.Fourthly, bio-oil is extracted using biodiesel to produce two fractions, a biodiesel-rich fraction (also referred as bio-oil/biodiesel blend) and a bio-oil rich fraction. The results has shown that the compounds (mainly phenolic) extracted from bio-oil into the biodiesel-rich fraction reduces the surface tension of the resulted biodiesel/bio-oil blends that are known as potential liquid transport fuels. The bio-oil rich fraction is mixed with ground biochar to produce a bioslurry fuel. It is found that bioslurry fuels with 10% and 20% biochar loading prepared from the bio-oil rich fraction of biodiesel extraction at a biodiesel to bio-oil blend ratio 0.67 have similar fuel properties (e.g. density, surface tension, volumetric energy density and stability) in comparison to those prepared using the original whole bio-oil. The slurry fuels have exhibited non-Newtonian with pseudoplastic characteristics and good pumpability desirable for fuel handling. The viscoelastic behaviour of the slurry fuels also has shown dominantly fluid-like behaviour in the linear viscoelastic region therefore favourable for atomization in practical applications. This study proposes a new bio-oil utilisation strategy via coproduction of a biodiesel/bio-oil blend and a bioslurry fuel. The biodiesel/bio-oil blend utilises a proportion of bio-oil compounds (relatively high value small volume) as a liquid transportation fuel. The bioslurry fuel is prepared by mixing the rest low-quality bio-oil rich fractions (relatively low value and high volume) with ground biochar, suitable for stationary applications such as combustion and gasification.Overall, the present research has generated valuable data, knowledge and fundamental understanding on advanced fuels from mallee biomass using pyrolysis as a pre-treatment step. The flexibility of pyrolysis process enables conversion of bulky, low fuel quality mallee biomass to biofuels of high volumetric energy density favourable to reduce logistic cost associated with direct use of biomass. The significance structural, fuel and ash properties differences among various mallee biomass components were also revealed. The production of bioslurry fuels as a mixture of bio-oil and biochar is not only to further enhance the transportability/handling of mallee biomass but most importantly the slurry quality highly matched requirements in stationary applications such as combustion and gasification. The co-production of bioslurry with bio-oil/biodiesel extraction was firstly reported in this field. Such a new strategy, which uses high-quality extractable bio-oil compounds into bio-oil/biodiesel blend as a liquid transportation fuel and utilises the low-quality bio-oil rich fraction left after extraction for bioslurry preparation, offers significant benefits for optimised use of bio-oil.

Electricity is the cornerstone of modern life. It is essential to economic stability and growth, jobs and improved living standards. Electricity is also the fundamental ingredient for a dignified life; it is the source of such basic human requirements as cooked food, a comfortable living temperature and essential health care. For these reasons, it is unimaginable that today's economies could function without electricity and the modern energy services that it delivers. Somewhat ironically, however, the current approach to electricity generation also contributes to two of the gravest and most persistent problems threatening the livelihood of humans. These problems are anthropogenic climate change and sustained human poverty.
To address these challenges, the global electricity sector must reduce its reliance on fossil fuel sources. In this context, the object of this research is twofold. Initially it is to consider the design of the Renewable Energy (Electricity) Act 2000 (Cth) (Renewable Electricity Act), which represents Australia's primary regulatory approach to increase the production of renewable sourced electricity. This analysis is conducted by reference to the regulatory models that exist in Germany and Great Britain. Within this context, this thesis then evaluates whether the Renewable Electricity Act is designed effectively to contribute to a more sustainable and dignified electricity generation sector in Australia.
On the basis of the appraisal of the Renewable Electricity Act, this thesis contends that while certain aspects of the regulatory regime have merit, ultimately its design does not represent an effective and coherent regulatory approach to increase the production of renewable sourced electricity. In this regard, this thesis proposes a number of recommendations to reform the existing regime. These recommendations are not intended to provide instantaneous or simple solutions to the current regulatory regime. Instead, the purpose of these recommendations is to establish the legal foundations for an effective regulatory regime that is designed to increase the production of renewable sourced electricity in Australia in order to contribute to a more sustainable and dignified approach to electricity production.

The book traces the development and consequences of the economic reform measures undertaken in the utilities sector in Australia (communications, energy, water/wastewater services, and transport) in the last years of the 20th century and the early decades of the 21st century. In doing so, it looks at the process of reform across industries, and across the state and federal jurisdictions, to identify what motivations the various governments had for pursuing reform, how change varied across jurisdictions, and what issues arose in the process. Although by the mid-1990s all states and territories and the Australian Government were committed to reforming utilities as part of the National Competition Policy, not all pursued this reform with the same degree of speed and breadth of action. The broad trends of economic reform in Australia, and abroad, are also touched upon, to provide an outline of the wider context in which the reform of the utilities occurred. This book, therefore, explores the relationship between politics and society on the one hand and economic reform on the other; as well as on the efforts of governments in Australia to promote economic growth and the wealth of Australians in an increasingly complex and challenging global economic climate.

Freshwater scarcity is a critical challenge, with social, economic, political and environmental consequences. Water crises in Australia have already led to severe restrictions being applied in cities, drought ravaging farmlands, and the near-terminal decline of some rivers and wetlands.
A Water Story provides an account of Australian water management practices, set against important historical precedents and the contemporary experience of other countries. It describes the nature and distribution of the country's natural water resources, management of these resources by Indigenous Australians, the development of urban water supply, and support for pastoral activities and agricultural irrigation, with the aid of case studies and anecdotes. This is followed by discussion of the environmental consequences and current challenges of water management, including food supply, energy and climate change, along with options for ensuring sustainable, adequate high-quality water supplies for a growing population.
A Water Story is an important resource for water professionals and those with an interest in water and the environment and related issues, as well as students and the wider community.

AbstractThe extensive use of media and information and communication technologies (ICTs) in the household is building a new normality, where the use of technology is imperceptible to its users. Within this context, home renovation can be examined as a mediatised practice, which suggests the interactive transformation of practices which takes place with and through media. Our chapter is based on an interdisciplinary Australian study of 13 home renovations and their media practices. In this chapter, we argue that home renovation activities have moved into the digital realm. Furthermore, we emphasise that these mediatised home renovation practices contribute to the development of new mediatised domains that could assist in the transition and domestication of low-carbon practices and technologies.

This chapter discussed the multi- sectoral bilateral cooperation between Australia and Bangladesh during and post-COVID-19-related to interregional trade, foreign investment, ready-made-garments export, education, blue economy, microfinance, tourism, renewable energy, and finally, fulfillment of targets of SDGs. How do diverse areas of bilateral cooperation between Bangladesh and Australia become more efficient and effective in resource utilization and bring socio-economic benefits? Advancement in economic cooperation in both the countries may be improved from trade and investment, enhancement of education using Australian model, improvement and enhancement in energy, blue economy, education, health, and RMG sector. Australian partnership will be helpful for government agencies, policy makers, and associated stakeholders of Bangladesh for future improvements and development interventions in diverse multisector areas. Emphasis needs to be given to ecofriendly sustainability as suggested by the author to meet the climate change and sustainability goals.

Faced with increasingly serious climate and environmental problems, the green transformation of the energy structure is imminent. Energy development is related to a country’s economic lifeline, and the level of energy green transition is a key factor in determining the degree of low-carbon economic development. As an important way to internalize the externalities of environmental behavior, the degree of perfection of economic policies has a direct impact on the energy transition process. As an important means to promote the adjustment of energy structure, economic policies can internalize the positive or negative externalities of corporate environmental behaviors, and play an unparalleled role in the process of promoting the green transformation of energy. This article takes Germany, France, Japan, and Australia as the research objects of the four countries with relatively advanced energy transition economic policy systems, and fully analyzes the above-mentioned countries’ practices in fiscal and taxation policies, green finance, and market systems, and combines China’s energy transition economic policies. Implementation status, and corresponding suggestions for the construction of China’s energy transition policy system.

The article, based on the current informational material, provides an overview of the mineral resource complex of Australia and the ways of its development in modern conditions. Modern requirements for the development of the fuel and economic complex of countries are caused by new challenges in connection with the need to follow the Paris Convention on Climate Change and the installation on decarbonization – a significant reduction and then a complete rejection of CO2 emissions from the combustion of hydrocarbons. The work shows that the process of "greening" Australia provides for the creation and implementation of a completely new paradigm for the development of the fuel and energy complex. This is a complete rejection of the extraction and use of coal, an increase in gas production in compliance with environmental requirements, the development and implementation of new technologies, the expansion of gas storage facilities and a network of pipelines, as well as the parallel development and introduction of renewable energy sources.

Abstract Shale resource development technology is being improved and optimized over the last decade as the industry has seen a sharp rise in production and IP rates in North America and most recently from Europe and Australia while initial activities are on the rise in Latin America, Middle East and China. Despite such improvements, if one takes a closer look at the performance of the wells, one will find that not all wells are producing commercially and for that matter even wells that are producing commercially not all hydraulic fracture stages are contributing. This scenario is further compounded with the fact that unconventional resource development has a narrow profit margin for the E&P operators and in turn for the service industry. The industry needs to focus on the balance between efficient deployment of fit-for-purpose technology with strict economics in mind. This conundrum potentially suggests that when dealing with shale resource one is faced with sweet spot identification in a basin / field and at the same time moving away from geometric (say every 250 ft.) selection of hydraulic fracture stages and placing stages where appropriate from a productivity point of view. This paper documents certain well defined criterion used to identify the sweet spot location within a field / basin for the optimal well placement. We further document the vital formation / zone characteristic related information that can define the placement for hydraulic fracture stages and thus move away from the arbitrary geometric placement. Such an optimized plan can allow placement of productive wells and frac stages and thereby enhancing productivity and reducing well drilling and stimulation expenses. The key is effective cost reduction. The paper illustrates the well placement optimization process through a combination of seismic attribute analysis combined with petrophysical and geochemical analysis via core and geophysical log measurements. The hydraulic fracture stage placement relies on the need to understand existing natural fracture system through geophysical log measurements and the interaction between the created hydraulic bi-wing tensile fracture and the surrounding shear fractures. The paper concludes by presenting examples from three basins demonstrating the practical application of the methodology.

Level crossing risk continues to be a significant safety concern for the security of rail operations around the world. Over the last decade or so, a third of railway related fatalities occurred as a direct result of collisions between road and rail vehicles in Australia. Importantly, nearly half of these collisions occurred at railway level crossings with no active protection, such as flashing lights or boom barriers. Current practice is to upgrade level crossings that have no active protection. However, the total number of level crossings found across Australia exceed 23,500, and targeting the proportion of these that are considered high risk (e.g. public crossings with passive controls) would cost in excess of AU$3.25 billion based on equipment, installation and commissioning costs of warning devices that are currently type approved. Level crossing warning devices that are low-cost provide a potentially effective control for reducing risk; however, over the last decade, there have been significant barriers and legal issues in both Australia and the US that have foreshadowed their adoption. These devices are designed to have significantly lower lifecycle costs compared with traditional warning devices. They often make use of use of alternative technologies for train detection, wireless connectivity and solar energy supply. This paper describes the barriers that have been encountered for the adoption of these devices in Australia, including the challenges associated with: (1) determining requisite safety levels for such devices; (2) legal issues relating to duty of care obligations of railway operators; and (3) issues of Tort liability around the use of less than fail-safe equipment. This paper provides an overview of a comprehensive safety justification that was developed as part of a project funded by a collaborative rail research initiative established by the Australian government, and describes the conceptual framework and processes being used to justify its adoption. The paper provides a summary of key points from peer review and discusses prospective barriers that may need to be overcome for future adoption. A successful outcome from this process would result in the development of a guideline for decision-making, providing a precedence for adopting low-cost level crossing warning devices in other parts of the world. The framework described in this paper also provides relevance to the review and adoption of analogous technologies in rail and other safety critical industries.

The test operation of the Tokyo Tech rotary-type solar reactor (2nd model) is scheduled to be carried out using the solar concentrating system of CSIRO (New castle, Australia) as an international collaboration research between Japan (Tokyo Tech) and Australia (CSIRO) in APP (Asia-Pacific Partnership on Clean Development and Climate) project. The rotary-type solar reactor is positioned at an elevation of about 17 m. The input of solar power for the test operation is planned to be 50 kW from the solar concentrating system with about 10 heliostats. The estimation of evolved H2 gas was calculated from the amount of evolved O2 gas and the energy conversion efficiency is evaluated from the estimated amount of evolved H2 gas and the input of solar energy. The two-step water splitting process with the reactive ceramics of ceria-based solid solution (0.8CeO2−0.2ZrO2 prepared by the polymerized complex method) was investigated using the solar simulator of concentrated Xe lamp beams for the test operation of the rotary-type solar reactor at CSIRO solar concentrating system. The amounts of O2 and H2 gases evolved in the two-step water splitting reaction with CeO2-ZrO2 solid solution were determined for the H2-generation reaction temperatures of 773, 1273 and 1473 K. The amounts of evolved H2 gas decreased with an increase of the reaction temperature, however, the lowering of H2 gas evolution at 1473 K was 20% in comparison with that at 773 K. The heating time of the reactive ceramics up to the O2-releasing reaction temperature is evaluated to 3 s, when the difference between the O2-releasing reaction temperature (1773 K) and the H2-generation reaction temperature (1473 K) is 300 K.

When looking for a location for a wave energy converter (WEC) installation, developers usually look for sites with high or very high wave energy resource. From this perspective, countries like Scotland or Ireland have made great effort to include this energy source in their energy mix due to their expected high untapped potential. However, higher resource carries marine operation restrictions. Because of that, the selection of a site for a WEC deployment, the installation, operation and maintenance factors have to be considered from the beginning. In this work an analysis of the suitable locations for the development of wave energy is performed based on the operation and maintenance (O&M) parameters. This study is performed across the globe coastlines taking the met-ocean climate data from Reguero et al (2011) global reanalysis database (GOW) developed at IH Cantabria. Firstly, an analysis of the global availability and accessibility levels is performed all around the globe taking different wave height thresholds into account. Seven specific locations (North-West Denmark, West of Ireland, Chile, North of Spain, West Portugal, South-West Australia and North of Scotland) with high interest on wave energy have been further analyzed and compared. Secondly, the O&M access limits are quantified in terms of the weather windows and the waiting period between available weather windows. A statistical analysis of these parameters is performed within different weather windows lengths (6 h, 12 h and 24 h). The seasonality of these parameters is also analyzed. Finally, a failure analysis will be carried out, simulating the repair operation along the lifecycle of the device for different failure rates and waiting times. The affection of this failure and repair scheme over the power production of a device analyzed previously in Andres et al (2014) will be presented. In this study, some locations with high resource (Spain, Nova Scotia) lead to medium to high accessibilities/availabilities due to the balance between resource and persistence of the weather conditions. Some locations with high resource such as Chile or Australia resulted inaccessible during very long periods of time due to the persistence of severe conditions and then not very recommended for novel converters with uncertain failure rates.

For sustainability of environment, legislations in EU, USA, Japan and Australia require manufacturers to take back their products at the End of Life (EOL) and recycle them. The concept of 6R (reduce, reuse, recycle, recover, redesign and remanufacture) is very important for this issue, while reuse has the highest energy and material recovery efficiency. In this study, an integrated product information model has been developed in UML to provide necessary information for any future decision making activities in the EOL stage, such as the replacement analysis of any used part or subassembly. This product information model represents not only product structure but its function, behavior, and their associations in different abstract levels to support replacement analysis of an existing component with a new or a used component available to company. This representation schema provides necessary information for any future decision making activities in the EOL stage, such as the replacement or reuse of any part or subassembly. In an analysis of replacement for a faulty component with a used or new component, this model provides all of the associations of the existing artifact with other artifacts and the environment, not just functional and space requirements, and the relevant modification(s) of the associated objects has to be verified.

This paper examines renewable energy developments on Aboriginal lands in North-West Western Australia at three scales. It first examines the literature developing in relation to large scale renewable energy projects and the Native Title Act (1993)Cwlth. It then looks to the history of small community scale standalone systems. Finally, it examines locally adapted approaches to benefit sharing in remote utility owned networks. In doing so this paper foregrounds the importance of Aboriginal agency. It identifies Aboriginal decision making and economic inclusion as being key to policy and project development in the 'scaling up' of a transition to renewable energy resources in the North-West.

The Sunshine Coast (unless otherwise specified, Sunshine Coast refers to the region which includes both Sunshine Coast and Noosa council areas) is a classic regional hotspot. In many respects, the Sunshine Coast has assets that make it the “Goldilocks” of Queensland hotspots: “the agility of the region and our collaborative nature is facilitated by the fact that we're not too big, not too small - 330,000 people” (Paddenburg, 2019); “We are in that perfect little bubble of just right of about everything” (Erbacher 2019). The Sunshine Coast has one of the fastest-growing economies in Australia. Its population is booming and its local governments are working together to establish world-class communications, transport and health infrastructure, while maintaining the integrity of the region’s much-lauded environment and lifestyle. As a result, the Sunshine Coast Council is regarded as a pioneer on smart city initiatives, while Noosa Shire Council has built a reputation for prioritising sustainable development. The region’s creative economy is growing at a faster rate that of the rest of the economy—in terms of job growth, earnings, incomes and business registrations. These gains, however, are not spread uniformly. Creative Services (that is, the advertising and marketing, architecture and design, and software and digital content sectors) are flourishing, while Cultural Production (music and performing arts, publishing and visual arts) is variable, with visual and performing arts growing while film, television and radio and publishing have low or no growth. The spirit of entrepreneurialism amongst many creatives in the Sunshine Coast was similar to what we witnessed in other hotspots: a spirit of not necessarily relying on institutions, seeking out alternative income sources, and leveraging networks. How public agencies can better harness that energy and entrepreneurialism could be a focus for ongoing strategy. There does seem to be a lower level of arts and culture funding going into the Sunshine Coast from governments than its population base and cultural and creative energy might suggest. Federal and state arts funding programs are under-delivering to the Sunshine Coast.

The research on thermotolerance acquisition in broiler chickens by temperature conditioning early in life was focused on the following objectives: a. To determine the optimal timing and temperature for inducing the thermotolerance, conditioning processes and to define its duration during the first week of life in the broiler chick. b. To investigate the response of skeletal muscle tissue and the gastrointestinal tract to thermal conditioning. This objective was added during the research, to understand the mechanisms related to compensatory growth. c. To evaluate the effect of early thermo conditioning on thermoregulation (heat production and heat dissipation) during 3 phases: (1) conditioning, (2) compensatory growth, (3) heat challenge. d. To investigate how induction of improved thermotolerance impacts on metabolic fuel and the hormones regulating growth and metabolism. Recent decades have seen significant development in the genetic selection of the meat-type fowl (i.e., broiler chickens); leading to rapid growth and increased feed efficiency, providing the poultry industry with heavy chickens in relatively short growth periods. Such development necessitates parallel increases in the size of visceral systems such as the cardiovascular and the respiratory ones. However, inferior development of such major systems has led to a relatively low capability to balance energy expenditure under extreme conditions. Thus, acute exposure of chickens to extreme conditions (i.e., heat spells) has resulted in major economic losses. Birds are homeotherms, and as such, they are able to maintain their body temperature within a narrow range. To sustain thermal tolerance and avoid the deleterious consequences of thermal stresses, a direct response is elicited: the rapid thermal shock response - thermal conditioning. This technique of temperature conditioning takes advantage of the immaturity of the temperature regulation mechanism in young chicks during their first week of life. Development of this mechanism involves sympathetic neural activity, integration of thermal infom1ation in the hypothalamus, and buildup of the body-to-brain temperature difference, so that the potential for thermotolerance can be incorporated into the developing thermoregulation mechanisms. Thermal conditioning is a unique management tool, which most likely involves hypothalamic them1oregulatory threshold changes that enable chickens, within certain limits, to cope with acute exposure to unexpected hot spells. Short-tem1 exposure to heat stress during the first week of life (37.5+1°C; 70-80% rh; for 24 h at 3 days of age) resulted in growth retardation followed immediately by compensatory growth" which resulted in complete compensation for the loss of weight gain, so that the conditioned chickens achieved higher body weight than that of the controls at 42 days of age. The compensatory growth was partially explained by its dramatic positive effect on the proliferation of muscle satellite cells which are necessary for further muscle hypertrophy. By its significant effect of the morphology and functioning of the gastrointestinal tract during and after using thermal conditioning. The significant effect of thermal conditioning on the chicken thermoregulation was found to be associated with a reduction in heat production and evaporative heat loss, and with an increase in sensible heat loss. It was further accompanied by changes in hormones regulating growth and metabolism These physiological responses may result from possible alterations in PO/AH gene expression patterns (14-3-3e), suggesting a more efficient mechanism to cope with heat stress. Understanding the physiological mechanisms behind thermal conditioning step us forward to elucidate the molecular mechanism behind the PO/AH response, and response of other major organs. The thermal conditioning technique is used now in many countries including Israel, South Korea, Australia, France" Ecuador, China and some places in the USA. The improvement in growth perfom1ance (50-190 g/chicken) and thermotolerance as a result of postnatal thermal conditioning, may initiate a dramatic improvement in the economy of broiler's production.
