Shanghai Electric Group said the Huai’an Salt Cavern Compressed Air Energy Storage demonstration project in Jiangsu, billed as the world’s largest CAES station, has been fully commissioned. The 600 MW facility provides 2,400 MWh of storage at about 71% conversion efficiency, using salt caverns 1,150–1,500 meters underground and a molten salt plus pressurized thermal water high-temperature adiabatic process without supplementary fossil-fuel combustion. Shanghai Electric supplied core equipment including air turbine units, generators, electric motors and molten salt storage tanks; the project is expected to generate 792 million kWh annually and cut CO₂ emissions by about 600,000 tons per year.
