4 FAQs about [Compressed Space Energy Storage Power Station]

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.

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.

How does salt cavern energy storage work?

Salt cavern compressed-air energy storage, dubbed as the underground "green power bank," stores electricity by compressing air into underground salt caverns during off-peak times. The air is then released during peak demand to generate electricity, balancing supply and demand, as China Group Media reported.

What is Jintan salt cavern energy storage project?

The second phase of Jintan Salt Cavern Compressed-Air Energy Storage Project plans to build two 350-megawatt non-supplementary fired compressed air energy storage units, with a total volume of 1.2 million cubic meters, making it the largest in unit capacity, storage volume, and efficiency.
