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 accelerate the development of compressed air energy storage projects?

Now, China is expected to accelerate the development of its far less prevalent compressed air energy storage (CAES) projects to optimize its power grid performance and move in a greener direction.

What is compressed air energy storage (CAES)?

Compressed air energy storage (CAES) is an effective solution for balancing this mismatch and therefore is suitable for use in future electrical systems to achieve a high penetration of renewable energy generation.

What is advanced compressed air energy storage (a-CAES)?

They will run on an updated version of the technology called advanced compressed air energy storage (A-CAES). A-CAES uses surplus electricity from the grid or renewable sources to run an air compressor.

Is compressed air energy storage a viable alternative to pumped hydro?

Another technology that's been in use for decades is compressed air energy storage (CAES), which can store energy on a grid scale and is billed as having the reliability of pumped hydro, without the same constraints on where you can build it.

Should China develop a CAES power plant based on underground air storage?

Based on China's current national conditions, several conclusions are drawn from this review. First, grid-level (100 MW and above) CAES power plants based on underground air storage are the first choice for developing CAES in China due to its mature technology and available geographical conditions.
