Technical FAQs 4

What is a vanadium flow battery?

Designed for a 20-year lifecycle, Sumitomo Electric Industries, Ltd.’s Vanadium Flow Battery System brings high energy efficiency to large-scale energy storage systems. The vanadium flow battery (redox flow battery), can absorb and stabilize the fluctuations of outputs predicated by renewable energy sources.

What is a vanadium redox flow battery?

Vanadium Redox Flow Batteries (VRFBs) have emerged as a promising long-duration energy storage solution, offering exceptional recyclability and serving as an environmentally friendly battery alternative in the clean energy transition. VRFBs stand out in the energy storage sector due to their unique design and use of vanadium electrolyte.

Are vanadium flow batteries flammable?

Perhaps its most notable point is that it is incombustible, which translates to no fire hazard. With vanadium flow battery, the charge/discharge cycle is unlimited (>100,000 cycles). Also the electrolyte is reusable after decommissioning. The electrolyte used in the battery is non-flammable as it is made of flame retardant materials.

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.
