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.
Long operational lifespan is one of the key advantages of VRFBs, in addition to its high recyclability and strong safety credentials. In VRFBs, energy capacity (liquid electrolyte ) and power output (cells) are decoupled and can be scaled separately. This design also reduces wear and tear on components, which contributes to a longer operational life.
