This energy storage project is supported technically by Prof. Li Xianfeng's group from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences. And the system was built and integrated by Rongke Power Co. Ltd.

The Dalian Flow Battery Energy Storage Peak-shaving Power Station was approved by the Chinese National Energy Administration in April 2016. As the first national, large-scale chemical energy storage demonstration project approved, it will eventually produce 200 megawatts (MW)/800 megawatt-hours (MWh) of electricity.

The first phase of the on-grid power station project is 100 MW/400 MWh. Based on China's average daily life electricity consumption of 2 kWh per capita, the power station can meet the daily electricity demand of 200,000 residents, thus reducing the pressure on the power supply during peak periods and improving power supply reliability in the southern region of Dalian.

Energy storage technology can help power systems achieve the strain and response capability needed after large-scale access to the power grid. It is also particularly important in facilitating the use of renewable energy, which is key to helping China achieve its carbon peak and carbon neutrality goals but is not always accessible due to variations in wind and sunlight, etc.
