Now, China is expected to accelerate the development of its far less prevalent compressed air energy storage (CAES) projects to optimize its power grid performance and move in a greener direction.
A compressed air energy storage (CAES) project in Hubei, China, has come online, with 300MW/1,500MWh of capacity. The 5-hour duration project, called Hubei Yingchang, was built in two years with a total investment of CNY1.95 billion (US$270 million) and uses abandoned salt mines in the Yingcheng area of Hubei, China’s sixth-most populous province.
Of all the types of energy storage in China, CAES will represent 10% by 2025 and then surge to 23% by 2030, if all goes to plan. The China Industrial Association of Power Sources (CIAPS) said in an April report that China’s total energy storage capacity topped the world at 43.44 GW at the end of 2021.
Once operational, the facility is expected to achieve a conversion efficiency of 72.1% and generate 420 million kWh annually—enough to power 350,000 households. The system incorporates China Energy Storage’s latest 300 MW CAES technology, featuring multi-stage compressors, high-load turbines, and advanced supercritical heat exchangers.
According to China Energy Storage Alliance, the new plant can store and release up to 400 MWh, at a system design efficiency of 70.4%. That's huge; current compressed air systems are only around 40-52% efficient, and even the two larger Hydrostor CAES plants scheduled to open in California in 2026 are only reported to be around 60% efficient.
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.
