National compressed air energy storage

What is compressed air energy storage?

"Compressed air energy storage", alongside pumped-storage hydroelectricity, is one of the most mature physical energy storage technologies currently available. It will serve for constructing a new energy system and developing a new power system in China, as well as a key direction for cultivating strategic emerging industries.

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 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.

What are the advantages of non-afterburning compressed air energy storage power generation?

The non-afterburning compressed air energy storage power generation technology possesses advantages such as large capacity, long life cycle, low cost, and fast response speed. The project makes full use of underground salt cavity resources with compressed air as the main medium.

When will the salt cave compressed air energy storage national test & demonstration project start?

On August 18, the main construction of the "Salt Cave Compressed Air Energy Storage National Test and Demonstration Project" begin in Xuebu town, marking the project’s entrance into the critical period of construction.

How much does China energy storage cost?

The CNY 2.15 billion ($300 million) project, backed by local state-owned enterprise Xinyang Construction Investment Group, CAES technology specialist China Energy Storage National Engineering Research Center (China Energy Storage), and two other state investment firms, is set for completion by the end of 2026.
