Cave energy storage industry chain

Who commissioned the first salt cavern for compressed air energy storage in China?

Chinese state-owned energy group Huaneng, Tsinghua University, and China National Salt Industry Group have commissioned the first salt cavern for compressed air energy storage in China. The Jiangsu Jintan Salt Cavern Compressed Air Energy Storage Project is located in Changzhou, Jiangsu province.

Does China support salt cavern energy storage?

The Chinese government currently offers robust support for the salt cavern energy storage industry and has incorporated CAES into the national “14th Five-Year Plan”, thereby providing substantial backing for research on salt cavern CAES.

How can large-scale energy storage be implemented in salt caverns?

Compressed air and hydrogen storage are two main available large-scale energy storage technologies, which are both successfully implemented in salt caverns . Therefore, large-scale energy storage in salt caverns will also be enormously developed to deal with the intermittent and fluctuations of renewable sources at the national or grid-scale.

What role do salt caverns play in energy storage?

With the demand for peak-shaving of renewable energy and the approach of carbon peaking and carbon neutrality goals, salt caverns are expected to play a more effective role in compressed air energy storage (CAES), large-scale hydrogen storage, and temporary carbon dioxide storage.

What is Feicheng salt cave compressed air energy storage power station?

The Feicheng Salt Cave Compressed Air Energy Storage Power Station technology was developed by the Institute of Engineering Thermophysics, Chinese Academy of Sciences. This technology has the advantages of large scale, low cost, long life, and environmental friendliness. It is one of the most promising large-scale energy storage technologies.

Are salt caverns a good choice for energy storage?

Among all the underground structures, due to their strong tightness/stability, lower proportion of cushion gas, and good operational flexibility, salt caverns are regarded as the most favorable choice for energy storage―especially for gas, hydrogen and compressed air .
