Tokyo Vanadium Flow Battery 2025

4 FAQs about [Tokyo Vanadium Flow Battery 2025]

Does Sumitomo Electric have a redox flow battery?

Sumitomo Electric has operated a 2 MW/8 MWh pilot vanadium flow battery in San Diego since December 2018 and is constructing a similarly sized facility on the island of Kyushu. Japan’s Sumitomo Electric is building the first redox flow battery to be approved for government subsidy in the country.

What is a vanadium redox flow battery?

To address this specific gap, Vanadium Redox Flow Batteries (VRFBs) have emerged as a powerful and promising technology tailored for large-scale energy storage , . The defining characteristic of a VRFB is the unique decoupling of its power and energy capacity.

What kind of flow battery does Sumitomo Electric use?

Sumitomo Electric also didn’t say exactly what kind of electrolyte-based flow battery it would deploy, but the company has typically used vanadium redox flow battery (VRFB) technology. The project will contribute to carbon neutrality and resilience in the face of natural disasters in the Oki Islands, it said.

Which redox flow battery is subsidized by Japan''s government?

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.
