Academic literature on the topic 'Electric power production Australia Technological innovations'

Electric energy production in small-scale hydropower stations is attractive from both an ecological and an economical point of view. Technological innovations and measures to lessen environmental impacts make small-scale hydropower stations inexpensive and justified energy sources that provide renewable energy on an independent basis and help not only to protect the environment but also to weaken human dependence on fossil fuels. This study is devoted to finding solutions based on renewable energy technologies and innovations in Uzbekistan. This article is devoted to the development of a water wheel experimental model for the micro-hydroelectric power station. Experimental studies were carried out on the basis of this model and obtained results were used in the preliminary calculations. The results from the calculations showed that the installation can generate 7-11 kWh of electricity per hour, about 168-264 kWh of electricity per day and 61 to 96 MWh of electricity per year.

The publication presents heat and electricity management in the Polish steel industry. The paper is based on actual data on heat and electricity consumption and intensity by processes in the steel industry in Poland in Industry 4.0 conditions. Two steel production processes are used in Poland: EAF Electric Arc Furnace and BOF Basic Oxygen Furnace. The analysis is an analysis of actual data is used to characterise the electricity and heat consumption by processes in the Polish steel industry. The analysis shows that the EAF technology is always more electricity intensive and the BOF technology more heat intensive. On the basis of conducted analysis, it can be concluded that pro-environmental innovations in the steel industry should first aim to reduce the electricity consumption of EAF technology and the heat consumption of BOF. An analysis of data for Poland for the period 2004–2020 shows that both cases occurred. The study shows that the heat consumption of BOF technologies has been steadily decreasing since 2010, and the electricity consumption of EAF technologies has been decreasing throughout the period under review. It can be concluded from this that the Polish steel industry is adapting to pro-environmental requirements and, through the introduction of technological innovations, is moving towards the concept of sustainable steel production according to green steel principles. The decrease in energy intensity (means electricity) of steel produced according to EAF technology is an important issue, as the high energy intensity of EAF processes affects the overall energy intensity of the steel production in Poland. In the future, the use of new innovative technological solutions, including solutions based on Industry 4.0 principles, should help the Polish steel industry to further reduce the level of electricity and heat consumption. The driving force behind the investment is the boom in the steel market. The authors made a short-term forecasts of steel production (2022–2025). The annual forecasts determined and analyses made were used to determine the heat and energy consumption of the Polish steel industry up to 2025.

The study is relevant due to increased interest to the underground coal gasification technologies (UCG). The interest is determined by the depletion of world oil and gas reserves, the significant amount of coal deposits in various countries of the world, the growing energy demand, as well as the threat of global climate change. The possibility to use technologies of underground gasification of low-grade coal with complex geological environment is huge. Recently, interest to UCG has grown dramatically. In contrast to all major programs of the 20th century, this unprecedented interest is mainly stimulated by private capital in response to high oil and energy prices. Thus, the studies of UCG are carried out. And more than 30 tests are planned in Australia, China, India, South Africa, New Zealand, Canada, and the United States. The development of competitive gas-based technologies of production of electricity and synthetic liquid fuels is a high-priority task. The studies have been carried out using a mathematical model of the unit for the production of electricity and methanol. To design a mathematical model, a software, or the system of machine programs development (SMPP) has been used. It has been developed at Melentiev Energy Systems Institute of Siberian Branch of the Russian Academy of Sciences (ESI SB RAS). The article presents the results of the study of the use of UCG for the coproduction of synthetic liquid fuel (methanol) and electricity. A detailed mathematical model of electricity and methanol production unit has been developed. Based on the model, technical and economic optimization of the schemes and parameters has been carried out. It made possible to estimate the competitiveness conditions of the proposed method of coal processing. In addition, the sensitivity of the economic indicators of the unit to changes in external conditions has been studied. Based on the results of the analysis of the cost of diesel fuel in the eastern regions of Russia, the authors have made the conclusion that at present methanol produced by the energy technological unit is as competitive as delivered expensive diesel fuel. The introduction of such systems is economically reasonable in the near future.

A general rise in environmental and anthropogenically induced greenhouse gas emissions has resulted from worldwide population growth and a growing appetite for clean energy, industrial outputs, and consumer utilization. Furthermore, well-established, advanced, and emerging countries are seeking fossil fuel and petroleum resources to support their aviation, electric utilities, industrial sectors, and consumer processing essentials. There is an increasing tendency to overcome these challenging concerns and achieve the Paris Agreement’s priorities as emerging technological advances in clean energy technologies progress.

The presented article analyzes innovative activity in the development of solar energy and its impact on the energy security of Ukraine. In particular, the innovative processes taking place in the global alternative energy sector and their impact on the management of the Ukrainian energy complex are researched. It is emphasized that innovations in the technological process of manufacturing polycrystalline silicon and increasing the volume of its production made it possible to exponentially reduce the cost of production of photocells from polycrystalline silicon (C-si). An evaluation of the current state of innovation activity and its management in the global alternative energy sector as a tool for ensuring Ukraine’s energy security, competitiveness and economic independence of the country is provided. The world total installed capacity of photovoltaic power plants is outlined with a forecast until 2025. The current legislation of Ukraine on alternative energy, energy conservation, efficient use of energy resources, development of renewable and alternative energy sources is analyzed. It is underlined that today the high self-cost of electricity production is a serious problem of the Ukrainian electric energy sector, so the current trend of reducing the cost of solar electricity production against the background of a constant increase in nominal prices is a positive signal for investors. The outlined statistics of increasing energy production from renewable sources indicate that the government sees its independence in the development of renewable energy sources, and companies developing solar energy are becoming competitive owing to the rapid reduction in the cost of electricity production compared to traditional types of energy, which is a promising direction of work in today’s conditions. The investment attractiveness of electricity production using silicon solar panels is emphasized.

The article deals with the relevance of more effective structural transformation through the introduction of new innovations using advanced world experience in the infrastructure complex of the energy sector of the Republic of Azerbaijan. In this regard, the study also reflects the analysis and research on the directions of formation of optimal infrastructure complex in the energy sector. For this purpose, new development targets have been identified in the first chain of the national energy sector infrastructure complex against the background of progressive world experience analysis. For this purpose, the experience of leading world countries in oil and gas industry, including the United States of America, people's Republic of China, Russian Federation, Great Britain, Japan, South African Republic, Norway and others has been studied. The learning spectrum also covered the experience of well-known transnational corporations, including “Statoil”, “Schlumberger”, “Rosneft”, “Gazprom”, “Lukoil” and others. The existing positive trends in this sphere were based on systematized for application in the first chain of infrastructure complex of the national energy sector. Based on this, based on the analysis, the following were identified as the directions of formation of optimal infrastructure complex in the first chain of the national energy sector: • creation of a broad spectrum of continuously renewing energy potential; • increasing efficiency of production and processing of oil, gas and other energy resources and strengthening innovative supply of their production; • technological renewal of the fuel and energy complex and transition to energy-efficient strategic development model in this sphere in order to meet the growing domestic demand of the economy and ensure exports; • formation of a new system of institutions for the broad liberalization of the fuel and energy market and improvement of the relevant regulatory and legal framework. In addition, the achievements of Turkey, the Russian Federation, the Federal Republic of Germany and Great Britain were analyzed and evaluated to determine the principles of transition to the liberal market model in the second chain of the national energy sector infrastructure complex. The main components of this advanced practice have also been unified for application. Also, based on the analysis and research carried out in accordance with the requirements of the law of the “Republic of Azerbaijan on efficient use of energy resources and energy efficiency”, the author has prepared a scheme reflecting the transition of the National Electric Power system to a liberal market model. Based on the analysis and assessments covering both links of the energy sector, the author has developed an oligopolistic market model of the national energy infrastructure complex. The classification composition of the transformation of the optimal infrastructure complex in the national energy sector includes the following: • deposits and gas supply organizations located in dry areas are excluded from the structure of SOCAR and he continues to work as a transnational company that exploits offshore oil fields. In its structure, it retains its assets outside the country, as well as oil refining, deep foundations production and other directly necessary service areas. At the same time, it is considered appropriate to include in its functions the production of renewable energy sources; • a separate oil and gas producer concern is being set up in public-private cooperation, which manages the oil and gas industry in onshore areas from exploration to filling stations. The concern also implements a strategy for renewable energy production by converting some of the mining areas into energy farms (solar, wind, hydrogen, fast-growing plants and ethanol production by planting trees). • a separate vertically integrated state gas company is established, which carries out the reception, treatment, processing, storage, transportation and supply of gas. It also includes carbamide and methanol plants operating directly on gas raw materials. The gas distribution area is fully or partially allocated for privatization or transferred to private companies in pilot form for management; • the independence of the oil and gas chemistry complex is also assessed separately. At the same time, it is expedient to join “SOCAR Polymer” Plant, which produces polymers, into this complex; • In line with the reforms carried out in the country, the electric power sector is moving to a liberal market Model. Power plants remain in the state's view at the initial stage. Taking into account the strategic goals of the state, starting with relatively small power plants, their transfer or full privatization to independent and mixed management on the basis of rigid investment agreements is considered. In this sphere “Transmission System Operator for electric power” is being created, which includes high voltage transmission lines under full control of the state. In addition, the organization “Market Operator for electric energy” is established, which carries out the processes of wholesale electricity in the energy system, and is also under the full control of the state. In the distribution network system of electricity, full or partial privatization is carried out. The final results of our analysis on the formation of an optimal infrastructure complex in the national energy sector show that a fundamental transition to a liberal market model should be made in the country, and an optimal infrastructure complex should be formed here. The new infrastructure complex should be formed in an oligopolic model, reflecting the achievements of the most progressive world experience. Natural, environmental, political and economic factors that optimally influence the Bur sphere should be taken into account, the tariff and tax system should be improved, and the next stage of development in the energy sector should find continuous stimulation within the framework of Public-Private Partnership. Keywords: energy infrastructure, oil and gas industry, electricity, innovations, oligopoly, digital twins.

Radical transformations of the Ukrainian energy system also caused changes in energy policy. However, the interpreted provisions did not provide for extraordinary differences regarding the modification of energy measures in terms of individual regions. These actions subsequently caused the institutional transformation of fuel, gas, and electric power measures on the way to economic liberalization. Energy policy combines legal, organizational, financial and economic regulation in the country's national policy context. Implementation of innovative technological improvements in the FEC allows for: modernization of the energy system; improvement of infrastructure; integrating advanced foreign practices into one's own system; application of innovations following the EU legislation; introduction of hydrogen technologies and the transition to clean energy. Creation of reserves to avoid the shortage of energy resources: formation of the legislation of Ukraine regarding the reservation of oil and gas storages; creation of an Eastern European gas and oil center (hub) in Ukraine; formation of a system of increasing price competition on European markets through reservation. Assimilation of experience and formation of established norms of behavior on energy saving includes: improvement of normative and legal aspects of the regulation of economic activity by business entities; technical improvement of production processes; application of systematic monitoring and energy audit; achieving the effect of scale during the production and consumption of energy resources. The energy efficiency of the use of resources in view of their diversity and the use of FEC allows for: reliability and continuity of energy supply; pricing; normative and legal instruments of regulation; projects related to the implementation of efficient energy use; measures to preserve the environment. Diversification in the application of RES in energy segments provides for: diversifying the ties with the countries of the energy society; resuming the cooperation with Poland through the ?winouj?cie LNG terminal in the context of gas and energy; activating the transit of energy resources through Slovakia, Moldova, and Romania. The function of the energy system following EU legislation and modern global challenges consists in: implementation of the priorities of the Green Deal; transition to clean energy; application of hydrogen energy; establishing the infrastructure for the use of RES.

Our present dependence on fossil fuels means that, as our demand for energy inevitably increases, so do emissions of greenhouse gases, most notably carbon dioxide (CO 2 ). To avoid the obvious consequences on climate change, the concentration of such greenhouse gases in the atmosphere must be stabilized. But, as populations grow and economies develop, future demands now ensure that energy will be one of the defining issues of this century. This unique set of (coupled) challenges also means that science and engineering have a unique opportunity—and a burgeoning challenge—to apply their understanding to provide sustainable energy solutions. Integrated carbon capture and subsequent sequestration is generally advanced as the most promising option to tackle greenhouse gases in the short to medium term. Here, we provide a brief overview of an alternative mid- to long-term option, namely, the capture and conversion of CO 2 , to produce sustainable, synthetic hydrocarbon or carbonaceous fuels, most notably for transportation purposes. Basically, the approach centres on the concept of the large-scale re-use of CO 2 released by human activity to produce synthetic fuels, and how this challenging approach could assume an important role in tackling the issue of global CO 2 emissions. We highlight three possible strategies involving CO 2 conversion by physico-chemical approaches: sustainable (or renewable) synthetic methanol, syngas production derived from flue gases from coal-, gas- or oil-fired electric power stations, and photochemical production of synthetic fuels. The use of CO 2 to synthesize commodity chemicals is covered elsewhere ( Arakawa et al. 2001 Chem. Rev. 101 , 953–996); this review is focused on the possibilities for the conversion of CO 2 to fuels. Although these three prototypical areas differ in their ultimate applications, the underpinning thermodynamic considerations centre on the conversion—and hence the utilization—of CO 2 . Here, we hope to illustrate that advances in the science and engineering of materials are critical for these new energy technologies, and specific examples are given for all three examples. With sufficient advances, and institutional and political support, such scientific and technological innovations could help to regulate/stabilize the CO 2 levels in the atmosphere and thereby extend the use of fossil-fuel-derived feedstocks.

Miniaturisation has been the holy grail of mobile technology. The ability to move around with our gadgets, especially the ones for communication and entertainment, has been what semiconductor scientists have battled over the past decades. Miniaturisation brings about reduced consumption in power and ease of mobility. However, the main impediment to untethered mobility of our gadgets has been the lack of unlimited power supply. The battery had filled this gap for some time, but due to the increased functionalities of these mobile gadgets, increasing the battery capacity would increase the weight of the device considerably that it would eventually become too heavy to carry around. Moreover, the fact that these batteries need to be recharged means we are still not completely free of power cords. The advent of low powered micro-controllers and sensors has created a huge industry for more powerful devices that consume a lot less power. These devices have encouraged hardware designers to reduce the power consumption of the gadgets. This has encouraged the idea of wireless power transmission on another level. With lots of radio frequency energy all around us, from our cordless phones to the numerous mobile cell sites there has not been a better time to delve more into research on WPT. This study looks at the feasibilities of WPT in small device applications where very low power is consumed to carry out some important functionality. The work done here compared two rectifying circuits’ efficiencies and ways to improve on the overall efficiencies. The results obtained show that the full wave rectifier would be the better option when designing a WPT system as more power can be drawn from the rectenna. The load also had a great role as this determined the amount of power drawn from the circuitry.
