The Nikkei reports that Hokkaido Electric Power Co. will invest in a 60,000 kWh vanadium redox flow battery from Sumitomo Electric Industries Ltd. to bolster its grid capacity amid rapid growth in power generation using renewable energy.

A redox battery is an electrochemical system that generates oxidation and reduction between two active materials, forming a redox system, on the surface of inactive electrodes (the electrodes themselves do not change). A redox flow (RF) battery has the electrolyte including these active materials in external containers, such as tanks, and charges and discharges electricity by supplying the electrolyte to the flow type cell by pumps or other means.
