1. Introduction. Energy crisis and environmental pollution issues are critical challenges affecting the daily lives of human beings around the world [1].The reserves of non-renewable fossil fuels such as coal, petroleum, and natural gas are gradually depleted [2], so it is necessary to seek sustainable and affordable energy
Global capability was around 8 500 GWh in 2020, accounting for over 90% of total global electricity storage. The world''s largest capacity is found in the United States. The majority of plants in operation today are used to provide daily balancing. Grid-scale batteries are catching up, however. Although currently far smaller than pumped
