A Chinese state-led consortium is developing a 300 MW/1200 MWh compressed air energy storage (CAES) project in Xinyang, Henan province, featuring an entirely artificial underground cavern—China''s first of its kind.
The completion of this project indicates that China''s compressed air energy storage technology has entered a new era of commercial operation, leading the world in the sector and offering solutions
Installation work has started on a compressed air energy storage project in Jiangsu, China, claimed to be the largest in the world of its kind. Construction on the project started on 18 December 2024, according to China state-owned news outlet CCTV.
Researchers from North China Electric Power University have looked into methods for improving the efficiency of compressed air energy storage (CAES) systems, which are used to store excess energy from solar and wind power plants.
The inclusion of detailed specifications for both electrochemical and compressed air energy storage facilities marks a significant step in aligning technical standards with the evolving demands of China''s modern energy infrastructure.
Designated as a pilot project under China''s National Energy Administration''s new energy storage initiative, the Xinyang facility pioneers an innovative air-sealing approach for artificial underground storage, offering a significant boost to the commercialization of CAES technology in China.
The intermittent nature of renewable energy poses challenges to the stability of the existing power grid. Compressed Air Energy Storage (CAES) that stores energy in the form of high-pressure air has the potential to deal with the unstable supply of

A state-backed consortium is constructing China’s first large-scale compressed air energy storage (CAES) project using a fully artificial underground cavern, marking a major step in the technology’s commercialization.
The intermittent nature of renewable energy poses challenges to the stability of the existing power grid. Compressed Air Energy Storage (CAES) that stores energy in the form of high-pressure air has the potential to deal with the unstable supply of renewable energy at large scale in China.
The system incorporates China Energy Storage’s latest 300 MW CAES technology, featuring multi-stage compressors, high-load turbines, and advanced supercritical heat exchangers. This design improves efficiency by 2% over its 100MW predecessor while reducing unit costs by 30%.

China is currently in the early stage of commercializing energy storage. As of 2017, the cumulative installed capacity of energy storage in China was 28.9 GW , accounting for only 1.6% of the total power generating capacity (1777 GW ), which is still far below the goal set by the State Grid of China (i.e., 4%–5% by 2020) .
Based on China's current national conditions, several conclusions are drawn from this review. First, grid-level (100 MW and above) CAES power plants based on underground air storage are the first choice for developing CAES in China due to its mature technology and available geographical conditions.
