Number of air energy storage power stations put into operation

How many kilowatts are in China's new energy storage projects?

[Photo/China Daily] The installed capacity of new energy storage projects that were put into operation during the first half of this year in China has reached 8.63 million kilowatts, equivalent to the total installed capacity of previous years in the country, according to the National Energy Administration (NEA).

How energy storage power stations are being built?

In terms of installed capacity, new energy storage power stations are now being built in a more centralized way and large scale with longer storage duration period, said the administration.

What are the new energy storage technologies in 2023?

Since 2023, a number of 300-megawatts-grade compressed air energy storage projects along with 100-megawatts-grade liquid flow battery projects begun construction. The new technologies including gravity storage, liquid air storage, carbon dioxide storage have been developed as well, according to the NEA.

How is the government advancing energy storage technologies?

The government has been continuously advancing energy storage technologies, with several compressed air energy storage, flow battery storage, and sodium-ion battery storage projects put into operation across the nation, Bian Guangqi, an NEA official, said at the conference.

How can compressed air energy storage improve the stability of China's power grid?

The intermittent nature of renewable energy poses challenges to the stability of the existing power grid. Compressed Air Energy Storage (CAES) that stores energy in the form of high-pressure air has the potential to deal with the unstable supply of renewable energy at large scale in China.

What is new energy storage?

New energy storage, or energy storage using new technologies such as lithium-ion batteries, liquid flow batteries, compressed air and mechanical energy, is an important foundation for building the country's new power system, which enjoys advantages such as quick response, flexible configuration and short construction timelines.
