READ MOREThe Yangtze River Delta is the most developed region of China, and consumes a large amount of clean energy natural gas. Large-scale underground energy storage facilities are urgently needed to ensure the reliable supply of natural gas. Due to lacking reservoirs and aquifer, salt cavern gas storage is the best choice in this region [6,
READ MOREEnergy storage systems are required to increase the share of renewable energy. Closed mines can be used for underground energy storage and geothermal generation. Underground closed mines can be used as lower water reservoir for UPHES. CAES systems store energy in the form of compressed air in an underground reservoir.
