Underground air compression energy storage project

4 FAQs about [Underground air compression energy storage project]

What is a compressed air energy storage project?

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.

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 compressed air energy storage (CAES)?

Storage needs to be cost effective, and it needs to be efficient, that is, we need to get a high proportion of the energy we put into storage back out again. Compressed air energy storage (CAES) is a promising, cost-effective technology to complement battery and pumped hydro storage by providing storage over a medium duration of 4 to 12 hours.

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.
