Technical FAQs 4

What is a compressed air energy storage station?

"The compressed-air energy storage station offers large capacity, long storage time (over 4 hours), and efficient response, making it comparable to small and medium-sized pumped storage power plants," Liu Yong, Secretary General of Energy Storage Application Branch of China Industrial Association of Power Sources told the Global Times on Wednesday.

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.

How does an energy storage power station work?

The energy storage power station has compressed and stored the ambient air under pressure in an underground salt cavern. When the electricity is required, the pressurized air is heated and expanded in an expansion turbine driving a generator for power production.

What is energy storage No 1?

The “Energy Storage No. 1” project utilizes the caverns of an abandoned salt mine, reaching up to 600 meters of depth, as its gas storage facility. This allows for a gas storage volume of nearly 700,000 cubic meters, translating into a single unit power output of up to 300 MW and a storage capacity of 1,500 MWh.
