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 new energy storage important?

New energy storage is an important foundation for building a new power system in China, enjoying the advantages of fast response, flexible configuration and short construction periods. "We believe that its (new energy storage) installed capacity is going to surge and will see rapid development in the sector," Chen said.

What is new energy storage?

With the world's largest station for iron-chromium flow battery starting a test run of 168 hours on Tuesday, the country has taken a step further in advancing new energy storage. New energy storage refers to energy storage using new technologies, such as lithium-ion batteries, liquid flow batteries, compressed air and mechanical energy.

What percentage of China's Energy Storage is lithium ion?

As of the end of 2022, lithium-ion battery energy storage took up 94.5 percent of China's new energy storage installed capacity, followed by compressed air energy storage (2 percent), lead-acid (carbon) battery energy storage (1.7 percent), flow battery energy storage (1.6 percent) and other technical routes (0.2 percent).

Can mega energy storage stations shave peak and modulate frequency?

Such mega energy storage stations can help shave peak and modulate frequency for the power system, enabling smooth grid operation, Li Jianwei, chief engineer of the State Power Investment Corporation Limited, told CMG.
