Japanese manufacturer Sumitomo Electric has released a new vanadium redox flow battery (VRFB) suitable for a variety of long-duration configurations.

Unveiled at Energy Storage North America (ESNA), held in San Diego from Feb. 25–27, 2025, the system applies “newly developed long life materials” which allows for a 30-year operational lifespan. Such a lifespan, which is subject to proper maintenance, enhances the system’s long-term cost effectiveness, the manufacturer said.
