6 FAQs about [Cave energy storage enterprise]

What is salt cavern compressed air energy storage?

Salt cavern compressed air energy storage refers to a method for compressing air into the huge cavity formed by water-solution-based salt mining during low electricity demand periods, and releasing air to drive an air turbine to generate electricity when it is needed.

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.

When did China's salt cavern energy storage project start?

Its construction started in 2018 and the plant went into service on Sept 30, 2021. Completion and operation of the first phase of the project was a breakthrough in China's salt cavern compressed air energy storage technology and a milestone of commercialization of new-type energy storage technology in the country.

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.

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 .

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.
