Summary: There is growing interest in transitioning to a carbon-neutral power system that depends on renewable energy sources, driven by concerns about greenhouse gas emissions, energy shortages, and global warming. However, the integration of renewable energy has introduced increased volatility and uncertainty into power system operations. Sector coupling, which involves connecting different energy domains to integrate production, consumption, conversion, and storage, offers a potential solution to meet the needs of each energy sector and reduce surplus energy generation and unnecessary carbon emissions. Despite difficulties in large-scale integration, low conversion efficiency, and economic feasibility, sector coupling presents opportunities to enhance the acceptance of renewable energy and achieve carbon neutrality in traditional power systems. This perspective paper explores the background, definition, components, functions, examples, limitations, and future prospects of sector coupling in rendering power systems carbon-neutral.

Summary: The main aim of this paper is to diagnose the impact of climate change on the energy sector by analyzing its scenario, causes, and solutions. It discusses the climate change scenario in India, performs a comparative difference analysis of selected climatic variables, predicts future climatic variables using the ARIMA model, investigates the interdependency between climate change and the electricity sector, presents the current electricity scenario and renewable power potential in India, and suggests open research challenges and recommendations for improving the energy sector. The analysis concludes that climate change and the energy sector are mutually connected, and reducing climate change impacts can be achieved through the improvement of the energy sector using renewable energy.

Summary: The global coal-to-gas transition in the power sector is limited by pipeline availability constraints, with only a small percentage of coal capacity located within 14 km of a nearby pipeline. While coal-to-gas conversion has the potential for emissions reductions, most countries' coal fleets lack access to low-cost natural gas resources, making a global transition unlikely.

Summary: This research investigates the renewable energy trends in the electricity sector of five South American countries from 1990 to 2020 and finds different situations in low-carbon transition. Argentina, Brazil, and Chile show a trend of low-carbon reverse transition, necessitating short-term energy policy measures. Venezuela experiences a decrease in energy consumption and an increase in electricity generation using fossil fuels. Uruguay sees an increase in energy consumption and continues to rely heavily on renewables.

Summary: Reducing greenhouse gas emissions from the steel industry is a top priority for mitigating climate change. This paper quantitatively analyzes the greenhouse gas reduction in steel mills by using hydrogen produced from electrolysis with renewable electricity, and compares different methods of using green hydrogen. The results show that direct use of hydrogen in steelmaking processes achieves the largest reduction in greenhouse gas emissions but has the highest cost. Converting byproduct gases into methanol offers better reduction and lower cost compared to converting them into methane. In the future, the cost of the methanol method is predicted to be lower than that of selling hydrogen.

Summary: The study showed that using renewable fuels can reduce the life-cycle greenhouse gas emissions of vehicles more effectively than a low carbon electricity mix. Plug-in hybrid vehicles may be more beneficial in achieving more ambitious climate goals for the automotive sector compared to battery-electric vehicles. Current climate policy instruments are inadequate in minimizing the climate impact of the automotive sector.

Summary: Despite low and volatile allowance prices, power generators' responses within the EU Emission Trading System (ETS) were consistent with economic theory. This is evidenced by the qualitative response of allowance prices to fuel prices, the value of allowance banking for compliance costs, and the complete pass-through of allowance costs in major European markets. These findings suggest that the EU ETS was more functional than previously recognized.
