According to a report by CCTV Finance,on September 12th, two units of the world’s largest salt cavern compressed air energy storage project were fully commissioned in Jintan, Jiangsu, marking a significant breakthrough in China’s key core technologies and system integration capabilities in the field of large-capacity salt cavern compressed air energy storage. The two units, each with a capacity of 350 megawatts, rank first in the world in terms of total installed capacity among salt cavern compressed air energy storage projects.
High-pressure air from a salt cavern located 1000 meters underground, with a pressure exceeding 130 atmospheres, is transported to the ground-level power plant to drive the generator set to produce a steady stream of clean green electricity. As an energy storage project, it can be charged and discharged approximately 330 times a year, with a storage capacity of 2.8 million kWh per charge. Once the project is operational, it can provide strong support for peak shaving and power supply guarantee in the power grid, and significantly enhance the consumption capacity of new energy sources such as wind power and photovoltaics.
