Recent news from the Huai'an Salt Cavern Compressed Air Energy Storage Pilot Project marks another significant achievement. The air turbine unit No. 2, supplied by Shanghai Electric Power Station Group, achieved a successful one-time grid connection and simultaneously reached full-load power generation. This milestone signifies the comprehensive operational commencement of the world's largest-scale compressed air energy storage power station. Furthermore, Shanghai Electric Power Station Group also provided the project with air-cooled generators, motors, and complete equipment sets for cold and hot molten salt storage tanks.
The project leverages a massive 980,000 cubic meter salt cavern resource located 1,150 to 1,500 meters underground in Huai'an. It involves the construction of two sets of 300-megawatt-class non-supplementary combustion compressed air energy storage units. Utilizing the world's first-of-its-kind "high-temperature adiabatic compression" technology, which combines molten salt and pressurized heat-transfer water for non-supplementary combustion heat storage, the project boasts multiple parameters that lead globally.
