Abstract:

Purpose The purpose of this paper is to highlight the opportunity for the energy policy in Brazil to tackle the very high cost-effectiveness potencial of solar energy to the power system. Three mechanisms to achieve ambitious reductions in the greenhouse gas emissions from the power sector by 2030 and 2040 are assessed wherein treated as solar targets under ambitious reductions in the greenhouse gas emissions from the power sector. Then, three mechanisms to achieve these selected solar targets are suggested. Design/methodology/approach This paper reviews current and future incentive mechanisms to promote solar energy. An integrated energy system optimization model shows the most cost-efficient deployment level. Incentive mechanisms can promote renewable sources, aiming to tackle climate change and ensuring energy security, while taking advantage of endogenous energy resources potential. Based on a literature review, as well as on the specific characteristics of the Brazilian power system, under restrictions for the expansion of hydroelectricity and ambitious limitation in the emissions of greenhouse gases from the power sector. Findings The potential unexploited of solar energy is huge but it needs the appropriate incentive mechanism to be deployed. These mechanisms would be more effective if they have a specific technological and temporal focus. The solar energy deployment in large scale is important to the mitigation of climate change. Originality/value The value of the research is twofold: estimations of the cost-effective potential of solar technologies, generated from an integrated optimization energy model, fully calibrated for the Brazilian power system, while tacking the increasing electricity demand, the expected reduction of greenhouse gas emissions and the need to increase the access to clean and affordable energy, up to 2040; proposals of three mechanisms to deploy centralized PV, distributed PV and solar thermal power, taking the best experiences in several countries and the recent Brazilian cases.

Abstract:

Excessive use of traditional energy sources such as fossil fuels has resulted in significant environmental deterioration. India is one of the world’s fastest-growing energy consumers, and it is making continual efforts to increase renewable energy generation. The use of renewable energy sources to generate electricity is expanding every day. Renewable energy integration with existing power systems is a difficult endeavor that necessitates strategy and development. Climate-friendly energy systems will result from the use of renewable energy sources in power generation, as they lower CO2 emissions caused by fossil fuels used in conventional power generation. This research looks at a renewable energy scenario using Gujarat as a case study, which is a leader in renewable energy generation. The policies taken by the Gujarat government to increase renewable energy’s participation in the energy mix, as well as the challenges and potential solutions for boosting the deployment of renewable energy sources across Gujarat, are discussed. This study can be used as a guide for policymakers and researchers in other states and around the world who want to boost renewable energy share.

Abstract:

The Ukrainian energy sector is one of the most inflexible energy sectors in the world as a result of the almost complete depreciation of the equipment of the main sources of power supply: nuclear, thermal, and hydropower. In connection with existing problems, there is a need to develop and use new energy-saving technologies based on renewable energy sources. In this proposed research, a regression model of renewable energy growth in the energy sector of Ukraine was developed. The studied literature reveals that the independent use of individual functioning elements of renewable energy sources function as the primary power source that is not an optimal solution for stable energy supply. This study proposes the use of hybrid renewable energy systems, namely a combination of two or more renewable energy sources that will help each other to achieve higher energy efficiency, accelerate the growth of renewable energy in the share of the Ukrainian energy sector and/or improve functioning with battery energy storages. Moreover, the use of hybrid renewable energy systems in Ukraine will reduce the human impact on the environment, realize the potential of local renewable energy resources and also increase the share of electricity generation from renewable energy sources. Therefore, mechanisms for managing state regulation of stimulating the development of hybrid renewable energy systems have been developed.

Abstract:

This article, written by JPT Technology Editor Chris Carpenter, contains highlights of paper IPTC 21348, “The Color of Energy: The Competition To Be the Energy of the Future,” by Hon Chung Lau, National University of Singapore, prepared for the 2021 International Petroleum Technology Conference, held virtually 23 March–1 April. The paper has not been peer reviewed. Copyright 2021 International Petroleum Technology Conference. Reproduced by permission. The author of the complete paper, for the purposes of this study, characterizes energies as brown, blue, or green. Brown energies are carbon dioxide (CO2)-emitting fossil fuels, such as gas, oil, or coal. Blue energies use carbon capture and storage (CCUS) technologies to remove the emitted CO2 from brown energies. Green energies are zero- or low-CO2-emitting renewable energies. By analyzing the CO2 intensity and levelized cost of energy of energy carriers of different colors, the author shows that renewable energies are best used in replacing fossil fuels in the power sector, where they have the greatest effect in reducing CO2 emission. Overview By 2017, only 11% of the world’s final consumption came from renewable energies, 85% came from fossil fuel, and 4% came from nuclear energy. Energy consumption can be divided into three sectors: power, transport, and thermal. At the time of writing, 26.4% of global power (electricity) consumption comes from renewable energies. In this sphere, renewable energies are making the most significant contribution in reducing CO2 emission. Forty-one percent of CO2 emission comes from electricity and heat, 21% from transport, and 21% from industry. Consequently, the key to global decarbonization is to decarbonize these three sectors. Green Energy Is Preferred Green energies consist of six major types: solar photovoltaic, solar thermal, wind, hydroelectricity, geothermal, and biomass. If 1 kWh of electricity generated by renewable energy (with the exception of biomass) is used to replace 1 kWh of electricity generated by fossil fuel, the net CO2 savings will amount to 0.8, 0.6, and 0.4 kg for replacing coal, oil, and natural gas, respectively. However, if 1 kWh of renewable electricity is used to generate green hydrogen (H2), which is then used for heat generation in industry, it will yield roughly 0.8 kWh of thermal energy, which replaces the same amount of thermal energy by natural gas. This amounts to a CO2 savings of only 0.16 kg CO2/kWh. Consequently, renewable power has the highest CO2 savings effect if it is used to replace fossil fuel for power generation rather than to replace fossil fuel for heat generation. Decarbonizing the Power Sector The power sector is easiest to decarbonize. The three methods foreseen to decarbonize the power sector are nuclear power, blue electricity generated by fossil-fuel power plants equipped with CCUS, and green electricity produced by renewables. The use of nuclear power plants is a country-specific issue. The dual challenge of nuclear plant safety and nuclear waste storage is a key sustainability issue. Recently, interest has been renewed in the idea of increasing investment in nuclear energy for decarbonizing the power sector. It is noteworthy that the countries for whom more than a quarter of their power generation is provided by nuclear energy are all in Europe.

Abstract:

Abstract. Three simple, empirical models for growth of power consumption in the renewable energy sector are compared. These are the exponential, logistic, and power-law models. The exponential model describes growth at a fixed relative growth rate, the logistic model saturates at a fixed limit, while the power-law model describes slowing, but unlimited, growth. The model parameters are determined by regression to historical global data for solar and wind power consumption, and model projections are compared to scenarios based on macroeconomic modelling that meet the 2∘ target. It is demonstrated that rational rejection of an exponential growth model in favour of a logistic growth model cannot be made from existing data for the historical evolution of global renewable power consumption y(t). It is also shown that the logistic model yields saturation of growth at unrealistic low levels. The power-law growth model is found to give very good fits to the data through the last decade, and the projections align very well with the scenarios. Power-law growth is equivalent to the simple law that the relative growth rate y′/y decays inversely proportional to time. It is shown that this is a natural model for growth that slows down due to various constraints, yet not experiencing the effect of a strict upper limit defined by physical boundaries. If the actual consumption follows the power-law curve in the years to come the exponential-growth null hypothesis can be correctly rejected around 2020.

Abstract:

This paper seeks to study and compare the historical and present-day financial performance and risk profile of the renewable energy and fossil fuel power sectors. Our findings are as follows. First, renewable energy power portfolios have historically shown more attractive investment characteristics including, on average, 12% higher annual returns, 20% lower annual volatility and 61% higher risk-adjusted returns. Second, investors perceive renewable energy power investments to be less risky than fossil fuel power investments, with the expected returns on debt to the fossil fuel power sector is at least 80 basis points higher than for expected returns on debt for the renewable energy power sector. Third, the main risk factors driving the risk perception of both renewable energy and fossil fuels are counterparty, grid and financial risks; counterparty risk is the most significant risk by far, followed by grid risk and then financial sector risk. Our findings have significant implications for investments in these technologies in India.

Abstract:

Abstract The European Union has set the target for energy sector decarbonization. Variable renewable energy technologies are necessary to reach this target, but a high level of variable renewable energy raises the flexibility issues. In this research paper, the flexibility issue is addressed by analysing possibility of sector coupling via power-to-heat and power-to-gas applications by using system dynamics approach. The model is applied to the case of Latvia. Model results show that power-to-heat is a viable flexibility measure, and with additional financial incentives, it can even help to move towards decarbonization of the energy sector. In the best scenario, heat from surplus power can cover 37 % from total heat production in 2050. Unfortunately, in spite of a well-developed gas infrastructure, power-to-gas application is still very immature, and, in the best-case scenario with high incentives in power-to-gas technologies, only 7 % from available power surplus could be allocated for power-to-gas technologies in 2050.

Abstract:

Energy is one of the most important inputs that supports Indonesia’s economy. The government utilises coal and oil as the main sources for power plants energy mix. However, the utilization of fossil fuel energy has been proven to pose negative impacts on the environment such as, increasing carbon dioxide emission which leads to global warming. This study analyses investment policy on increasing electricity production of geothermal power plants as well as substitution of fossil energy to geothermal energy using Computable General Equilibrium (CGE) Model and Indonesia’s data of Social Accounting Matrix 2008. The result shows that when investment on the substitution of energy from fossil to renewable energy takes place, economic growth will increase and carbon dioxide emission will reduce significantly.

Abstract:

The purpose of the article is to identify and clarify the main features of the functioning and implementation of the antimonopoly compliance system at electric power enterprises. The main idea of the article is to use various methods (analysis, induction, etc.) to conduct a study of changes in domestic legislation that relate to the legislative consolidation of the antimonopoly compliance system. Based on statistical data and data from scientific sources, we can identify the main areas of activity of energy companies, where violations of antitrust legislation are most common, which will be identified and prevented by the antitrust compliance system. The scientific novelty of this article is confirmed by the almost absent publications of other authors, which study the effectiveness of the antimonopoly compliance system in the field of electric power industry. The author comes to the conclusion that the antitrust compliance system is an effective mechanism that allows identifying antitrust risks both inside the company and outside it. An increase in the number of companies that have antitrust compliance services will reduce the number of illegal violations by unscrupulous market participants, while these circumstances affect not only the electric power industry, but also other areas of the Russian economy. According to the author, the implementation of antitrust compliance will help to: l) reduce the number of offences committed by companies; 2) to prevent the actions of employees, which may in its work, to violate the antitrust laws; 3) to reduce the number of anti-competitive actions. Availability of antitrust compliance within the company promotes as corporate ethics, and the adoption by the staff of the values of the organization.

Abstract:

The development of a power system based on high shares of renewable energy sources puts high demands on power grids and the remaining controllable power generation plants, load management and the storage of energy. To reach climate protection goals and a significant reduction of CO2, surplus energies from fluctuating renewables have to be used to defossilize not only the power production sector but the mobility, heat and industry sectors as well, which is called sector coupling. In this article, the role of wastewater treatment plants by means of sector coupling is pictured, discussed and evaluated. The results show significant synergies—for example, using electrical surplus energy to produce hydrogen and oxygen with an electrolyzer to use them for long-term storage and enhancing purification processes on the wastewater treatment plant (WWTP). Furthermore, biofuels and storable methane gas can be produced or integrate the WWTP into a local heating network. An interconnection in many fields of different research sectors are given and show that a practical utilization is possible and reasonable for WWTPs to contribute with sustainable energy concepts to defossilization.

Abstract:

Abstract The study examines the impact of key determinants of profitability of power and energy sector in Pakistan such as firm size, firm age, firm growth, productivity, financial leverage and electricity crisis discussed in the broader inter-disciplinary literature. For this purpose panel data of 16 firms of power and energy sector is taken for 2001 to 2012. The study considers profitability determinants at the firm as well as industry affiliation levels in examining hypotheses developed from resource-based approaches. Random effect model is used to detect the combination of variables that best estimated the impact of the explanatory variables on the dependent variable. The empirical results suggest that firm size, firm growth, and electricity crisis positively impact the profitability. However, firm age, financial leverage and productivity negatively influence the firm profitability. This study also propose that during the electricity crisis the profitability of power sector is increased even production of this sector is very low. The findings further indicate that larger and younger firms with high growth and low productivity are more likely to be profitable. This study has found that firm productivity and firm size are the strongest determinants of profitability in power and energy sector of Pakistan.

Abstract:

Pakistan significantly contributes to the overall economy of South Asia, but, for many years, it has been facing a severe energy crisis. Despite the robust economic growth and a sharp increase in energy demand, no deliberate efforts have been made to meet the energy demand of the country. Similar to other developing countries, foreign direct investment (FDI) plays a key role in the economic development of this country. Pakistan receives FDI from many countries in various sectors of the economy. This paper aims to highlight the present situation of the power and energy sector of Pakistan (PESP), and empirically analyze the causality among the FDI in the power and energy sector, the energy consumption, and the economic growth of Pakistan for the period 1990–2017. The Johansen co-integration and Granger causality tests were employed to find the causal relationships among the variables of interest in the short-run and the long-run. The sector-wise flow of FDI reveals that the power and energy sector of Pakistan (PESP) has comparatively received a higher amount of FDI than other sectors of the economy in recent years. Furthermore, trends of energy production and energy usage reveal a substantial gap in previous years. The results confirm a positive bi-directional short-run causal relationship between economic growth and energy consumption. The results also reveal the presence of long-run causality in the equation of energy consumption. Considering the current situation of PESP, policy-makers should formulate policies to attain the minimum debt level and discourage loan-based investment. Such policies would be helpful to control the severe energy crisis and increase economic growth.

Abstract:

The article substantiates the necessity and possibility of preserving coal in the power industry as a fuel of the future, using the appropriate technology, based, to a large extent, on the use of layered combustion technology. The advantages and disadvantages of coal combustion in a layer are analyzed. The need to switch to flaring coal combustion to increase the unit capacity of the boiler is noted. The universality of this method of coal combustion in relation to its thermal properties is indicated. The sources of problems with emissions into the atmosphere during coal flaring are given. Shown is the substitution of the concept of "dirty technology" with the concept of "dirty fuel" in relation to coal fuel. The ways of returning to the layered combustion of coal are indicated, with the provision of the required capacity of the power facility through the installation of an increased number of boilers with lower productivity. It is noted that at the Almaty University of Energy and Communications named after Gumakrbek Daukeev, a coal combustion technology with reduced disadvantages is being developed The possibility of using flammable volatiles contained in coal for kindling a boiler and for stabilizing the ignition of a coal flame is noted. the possibility of supplying residents of a remote village with their own gaseous fuel for cooking was considered. The possibility of using this gaseous substance for the generation of electrical energy with the installation of low-power gas turbine units on a boiler with coal layer combustion is indicated. Based on such a comprehensive analysis of the advantages and disadvantages of coal, a conclusion was made about the long-term preservation of coal in the power industry.

Abstract:

Fossil fuels have been heavily exploited since the Industrial Revolution. The resulting carbon emissions are widely regarded as being the main cause of global warming and climate change. Key mitigation technologies for reducing carbon emissions include carbon capture and storage (CCS) and renewables. According to recent analysis of the International Energy Agency, renewables and CCS will contribute more than 50% of the cumulative emissions reductions by 2050. This paper presents a new mathematical programming model for multi-footprint energy sector planning with CCS and renewables deployment. The model is generic and considers a variety of carbon capture (CC) options for the retrofit of individual thermal power generation units. For comprehensive planning, the Integrated Environmental Control Model is employed in this work to assess the performance and costs of different types of power generation units before and after CC retrofits. A case study of Taiwan’s energy sector is presented to demonstrate the use of the proposed model for complex decision-making and cost trade-offs in the deployment of CC technologies and additional low-carbon energy sources. Different scenarios are analysed, and the results are compared to identify the optimal strategy for the energy mix to satisfy the electricity demand and the various planning constraints.

Abstract:

After decades of sustained economic growth, Australia is experiencing declining productivity, accelerating technological change and disruption. At the same time, the energy sector is emerging from a massive investment phase, while facing its own perfect storm of disruptive challenges. The industry must navigate these challenges to remain globally competitive. Continuing old practices is a sure pathway to stagnation and decline; we must urgently find different ways to do things. Global benchmarking of the Australian energy resources sector, undertaken recently on behalf of NERA, indicated substantial room to improve the efficiency and productivity of the sector. The report outlines more than AU$5 billion of value through improvements across the following four key areas: supply chain, research and innovation, workforce and regulatory reform, and collaboration is the key. Over the past 24 months, Australian energy-resource companies have focussed on lowering capital cost and improving profitability through efficiency, ensuring the industry has the fundamentals needed to be globally competitive. However, transformational change is needed if the sector is to survive and thrive in this age of innovation and disruption. Further, Australia’s energy resources marketplace is too small to focus only internally. Industry, suppliers, innovators and knowledge experts must collaborate locally, forming connections to access the global marketplace. The size of the prize is significant for everyone. The Australian energy resources sector has the potential to continue to meet the regions energy-resource needs for many years, generate substantial revenue for the nation and grow an export-orientated service and technology sector.

Abstract:

This paper is prepared on the answer to the valuable comments made by late Jeewan P. Thanju on my article ‘Water Resources of Nepal: Misconception and Reality’ published in The Rising Nepal on January 23 & 24, 2014.The rivers of Nepal possess sufficient hydropower potentiality to enhance the country’s socio-economic development. However, some spurious expert and vested interest group exaggerated the hydro potentiality and distorted the fact of water resources development prospective in Nepal. This has created confusion among the policymakers, politician and multilateral agencies. As a result, hydropower development in Nepal has headed for wrong course, and now the power sector, the vital impetus for socio-economic development is in dire strait. This paper highlights the uniqueness and distinct technical features of Nepalese Power Sector. In this paper important component like Integrated National Power System/Grid (INPS), Power Generation Modality (Hydropower, Thermal/Nuclear Plants and Diesel Plants) are well described and Master Plan, Project Selection, Construction Schedules and Hydropower potentiality of Nepal are discussed in detail. In a severe power and energy crisis situation in the country, power export is not recommended. Nepal needs 3000 MW to reach the level of other south Asian nations. INPS is owned and operated by NEA; therefore NEA also has the responsibility to prepare master plan for power generation, transmission and distribution. But, the Department Electricity Development a regulatory body of Ministry of Energy of is undertaking / carrying out feasibility study without taking care of INPS/country’s power requirement. This has created duplication of work and confusion; as such the Ministry of Energy deviated from its responsibility of preparing sound policy, regulation and monitoring them strictly. The Ministry shouldn’t indulge in feasibility study, construction and operational activities, which come under the responsibility of concerned technical department /authority.

Abstract:

Clean energy transition is one of major transformation processes in the EU. There are different approaches among EU countries to decarbonization of their energy systems. The article deals with clean energy transition in France with the emphasis on power generation. While this transformation process is in line with similar developments in the EU, the Franch case has its distinct nature due to nuclear power domination in electricity production there. It represents a challenge for the current model as the transition is linked to a sharp drop of nuclear share in the power mix. It is important to understand the trajectory of further clean energy transition in France and its ultimate model. The article reviews the historical roots of the current model (which stems from Messmer plan of the 1970-es) and its development over years, as well as assesses its drawbacks and merits in order to outline possible future prospects. The conclusion is that the desired reduction of nuclear energy is linked not solely to greening process but has a complex of reasons, the ageing of nuclear reactors being one of them. Nuclear power remains an important low-carbon technology allowing France to achieve carbon neutrality by 2050. A desired future energy model in France can be understood based on the analysis of new legislation and government action plans. The targeted model is expected to balance of nuclear and green energy in the generation mix in 50% to 40% proportion by 2035, with the rest left to gas power generation. Being pragmatic, French government aims at partial nuclear reactors shut down provided that this will not lead to the rise of GHG emissions, energy market distortions, or electricity price hikes. The balanced French model is believed to be a softer and socially comfortable option of low-carbon model.

Abstract:

The prospects of the Russian nuclear power industry depend on many factors, including economic, technological, political, social, and other aspects of the development of the global energy market. To increase the competitiveness of the Russian nuclear power industry, it is necessary to strengthen the existing advantages of Rosatom State Corporation, as well as state support for programs aimed at the development of nuclear technologies, both in the energy sector and in other sectors of the economy, including healthcare. The issues of developing international cooperation are particularly relevant when realizing the export potential of Russian nuclear energy.

Abstract:

The energy crisis in Uganda has caused a sharp decline in the growth of the industry sector from 10.8% to 4.5% between 2004/5 and 2005/6. This crisis has escalated the power disruptions, which have had adverse effects on various sectors. While business owners have resorted to importation of fossil fuel generators that have increased the cost of production, others have resorted to battery energy storage systems to cater for short outages, which are limited in life span, depth of discharge, among others. These interventions have, thus, further in-creased the cost of goods and services. In addition, the rural populations using solar home systems incur high battery maintenance and replacement costs. In this paper an electromechanical flywheel battery is proposed as a better alternative in mitigating energy storage problems. It is found that by replacing the battery storage systems with the electromechanical flywheel battery, a saving of up to 35% on cost of energy can be made in the solar home systems and for the industry sector, the power disruptions could be reduced.

Abstract:

Constant power supply is the hallmark of a devel-oped economy. Any nation whose energy need is epileptic in supply, prolongs her development and risks losing potential investors. Nigeria, a country of over 120 million people, has for the past 33 years of establishment of the National Electric Power Authority (NEPA) agency empowered with the elec-tricity generation, transmission and distribution, wit-nessed frequent and persistent outages. Presently, the federal government has embarked on power sector reforms with the intention of improving the above unpalatable scenario and in turn reduce the scope of monopoly control of the nation’s power industry. This paper therefore looks at the overall power sector reforms as well as evaluates the opportunities and challenges there from; while advocating introduction of a demand side manage-ment (DSM) program by Power Holding Company of Nigeria (PHCN) as a way of reducing energy con-sumption among customers with emphasis on ener-gy conservation, energy efficiency and load man-agement.

Abstract:

As for research on sector-coupled energy systems, few studies comprehensively deal with energy carriers and energy demand sectors. Moreover, few studies have analyzed energy conversion functions such as Power-to-Gas, Power-to-Heat, and Vehicle-to-Grid on the energy system performance. This study clarifies the required renewable resources and costs in the sector-coupled energy system and cost-optimal installed capacity and operation. We formulated an optimization model considering sector coupling and conducted a case study applying the model in the Tohoku region. As a result, due to sector coupling, the total primary energy supply (TPES) is expected to decrease, and system costs are expected to increase from 1.8 to 2.4 times the current level. System costs were minimized when maximizing the use of V2G by electric vehicles and district heating systems (DHS). From the hourly analysis, it becomes clear that the peak cut effect by Power-to-Heat and the peak shift effect by Vehicle-to-Grid result in leveling the output of electrolyzer and fuel synthesizer, which improves the capacity factor reducing capacity addition. Since a large amount of renewable energy is required to realize the designed energy system, it is necessary to reduce the energy demand mainly in the industrial sector. Besides, in order to reduce costs, it is required to utilize electric vehicles by V2G and provide policy support for district heating systems in Japan.

Abstract:

High electricity demand, as well as emissions generated from this activity impact directly to global warming. Mexico is paying attention to this world difficulty and it is convinced that sustainable economic growth is possible. For this reason, it has made actions to face this problem like as launching constitutional reforms in the power sector. This paper presents an energy model to optimize the grid of power plants in the Mexican electricity sector (MES). The energy model considers indicators and parameters from Mexican Energy Reforms. Electricity demand is defined as a function of two population models and three electricity consumption per capita. Prospectives are presented as a function of total annual cost of electricity generation, an optimal number of power plants—fossil and clean—as well as CO2eq emissions. By mean of the energy model, optimized grid scenarios are identified to meet the governmental goals (energy and environment) to 2050. In addition, this model could be used as a base to identify optimal scenarios which contribute to sustainable economic growth, as well as evaluate the social and environmental impacts of employed technologies.
