While expanding power generation capacity from new energy, China will also accelerate its energy storage development to help realize its carbon reduction pledge.
China temporarily targets to increase its new-type energy storage capacity to 30 GW by 2025, according to a draft plan co-issued by the National Development and Reform Commission (NDRC) and National Energy Administration (NEA) for public opinion on April 21.
The "new-type" energy storage refers to the storage methods other than pumped hydro storage (PHS), mainly including electrochemical energy storage.
The 30-GW goal is a relatively conservative compared with the forecasts from China Energy Storage Alliance (CESA).
China's total installed energy storage capacity reached 35.6 GW by the end of 2020, accounting for 18.6% of the world's total. The PHS capacity stood at 31.79 GW, taking the lion's share of 89.3% of China's total, while electrochemical energy storage was at 3.27 GW, making up 9.2%, according to the a report compiled by the CESA on April 14.
The year-on-year growth of electrochemical energy storage capacity stood at 91.2%, far higher than 9.8% of PHS, CESA said.
CESA forecast that China's electrochemical energy storage capacity would reach 5.79 GW in 2021 and increase to 35.52 GW in 2025, which was a conservative projection compared with CESA's another projection, at 55.88 GW for the ideal situation.
