How big is China's energy storage capacity?

As of the end of 2022, the total installed capacity of energy storage projects in China reached 59.4 gigawatts (GW), with pumped storage taking up to about 77 percent and new energy storage accounting for about 22 percent, according to Chen Haisheng, a researcher from the Institute of Engineering Thermophysics under the Chinese Academy of Sciences.

Why is energy storage technology needed in China?

In China, RES are experiencing rapid development. However, because of the randomness of RES and the volatility of power output, energy storage technology is needed to chip peak off and fill valley up, promoting RES utilization and economic performance.

How is energy stored in China?

In the eastern Chinese city of Changzhou, Jiangsu, air compressed to over 120 atmospheres in salt caverns 1,000 meters underground is used for energy storage. The heat generated is transferred to thermal oil and then the electricity is regenerated on command.

Is energy storage a key innovation field in China?
