China power engineering energy storage group factory operation

Will China's first large-scale compressed air energy storage project be commercialized?

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.

What is the energy storage project on Jurong Island in Singapore?

An energy storage project on Jurong Island in Singapore was put into operation in early December 2022. Generally contracted by China Energy Engineering Group Shanxi Electric Power Engineering Co., Ltd., the project has a designed capacity of 200 megawatts/200 megawatt-hours, the largest of its kind in Southeast Asia.

What is Xinyang air storage?

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.

How is China energy storage building a CAES facility?

Construction involves precision blasting, structural reinforcement, concrete lining, and a sealed steel layer to withstand an operating pressure of 14MPa. The project is led by China Energy Storage’s Henan subsidiary, which has previously developed multiple CAES facilities, including 100 MW, 150 MW, and 300 MW installations.

What is China energy storage?

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%.

Could a cavern be China's first underground energy storage project?

A 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.
