What is vanadium flow storage technology?
Vanadium flow storage technology uses the flow of vanadium electrolyte across an ion exchange membrane. The advantages of this type of storage are safety, scalability and long-term operation. Vanadium electrolyte used in this battery is non-flammable and the battery operates at room temperature.
Does Sumitomo have a solar energy storage system?
Sumitomo Electric Industries, Ltd. is pleased to announce that its vanadium redox flow battery (hereinafter "RF battery*1”), together with its energy management system sEMSA™,*2 has been adopted as the energy storage system for the "Kurokiyama Solar Power Plant," which was developed by Minamikyushu City, Kagoshima Prefecture.
Japan's Sumitomo Electric is building the first redox flow battery to be approved for government subsidy in the country. The 2 MW/8 MWh facility, which is under construction on the island of Kyushu, will be subsidized under Japan's FY2024 Renewable Energy Expansion and Grid-Scale Energy Storage System Support Program.
Where is Sumitomo Electric launching a long-duration energy storage project?
In December, the company announced the start of commercial operations at a 1MW long-duration energy storage (LDES) project in Niigata prefecture, further north of the coast of the Sea of Japan. At the time of the announcement, Sumitomo Electric said it had reached a total installed capacity of 50MW/176MWh of VRFBs across Japan.
