The first phase of a mega power storage project has been put into operation in Dalian and connected to the grid. With a final storage capacity of 400 MWh, the Dalian Concurrent Energy Storage Power Station is designed to increase the utilization of clean energy and ensure grid stability. All-vanadium liquid flow batteries use vanadium ions of different valence as the active material to achieve mutual conversion of electrical and chemical energy. The system developed at CAS Dalian Institute of Chemical Physics has high safety, good reliability, large output power and energy storage capacity, long life, high cost performance, recyclable electrolyte and thus promising applications in the field of large-scale energy storage.
