Which energy storage systems are being commercialised in China?

In addition to lithium-ion batteries, China is commercialising other types of energy storage systems. This includes the compressed air energy storage (CAES) technology, which consists of two stages.

Why is energy storage important in China?

Developing energy storage is an important step in China's transition from fossil fuels to renewable energy, while mitigating the effect of new energy's randomness, volatility and intermittence on the grid and managing power supply and demand, he said.

Where does China's storage capacity come from?

The majority of China’s storage capacity comes from large-scale storage projects, such as hydropower with reservoirs on the Yangtze River and gigawatt-level battery energy storage systems in Inner Mongolia.

Is China's power storage capacity on the cusp of growth?

China's power storage capacity is on the cusp of growth, fueled by rapid advances in the renewable energy industry, innovative technologies and ambitious government policies aimed at driving sustainable development, experts said.

How does China promote battery storage?

To promote battery storage, China has implemented a number of policies, most notably the gradual rollout since 2017 of the “mandatory allocation of energy storage” policy (强制配储政策), which is also known as the “ new energy plus storage ” model (新能源+储能).
