Proportion of installed capacity of each type of energy storage

What is the cumulative installed capacity of energy storage projects?

The cumulative installed capacity of new energy storage projects is 21.1GW/44.6GWh, and the power and energy scale have increased by more than 225% year-on-year. Figure 1: Cumulative installed capacity (MW%) of electric energy storage projects commissioned in China (as of the end of June 2023)

What types of energy storage are included?

Other storage includes compressed air energy storage, flywheel and thermal storage. Hydrogen electrolysers are not included. Global installed energy storage capacity by scenario, 2023 and 2030 - Chart and data by the International Energy Agency.

How much energy storage does China have in 2023?

By the end of 2023, China had completed and put into operation a cumulative installed capacity of new type energy storage projects reaching 31.4GW / 66.9GWh, with an average storage duration of 2.1 hours. The newly added installed capacity in 2023 was approximately 22.6GW / 48.7GWh, which is three times that for 2022 (7.3GW / 15.9GWh).

What is China's current energy storage capacity?

As of 2022, China's installed energy storage capacity is over 30 GW. In July 2021, China announced plans to install over 30 GW of energy storage by 2025 (excluding pumped-storage hydropower), a more than three-fold increase on its installed capacity as of 2022.

How big is China's energy storage capacity?

According to incomplete statistics from CNESA DataLink Global Energy Storage Database, by the end of June 2023, the cumulative installed capacity of electrical energy storage projects commissioned in China was 70.2GW, with a year-on-year increase of 44%.

What percentage of energy storage is pumped?

Pumped hydro accounted for less than 70% for the first time, and the cumulative installed capacity of new energy storage（i.e. non-pumped hydro ES） exceeded 20GW.
