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.

Why should you lease a vanadium battery?

Because vanadium electrolyte doesn't degrade, it is an appropriate commodity for leasing. The customer then has an operating expense rather than a capital expense. This also provides comfort to the customer as at the end of the battery's life the electrolyte belongs to someone else who will then be responsible for retrieving and repurposing it.

Why is vanadium a problem?

However, as the grid becomes increasingly dominated by renewables, more and more flow batteries will be needed to provide long-duration storage. Demand for vanadium will grow, and that will be a problem. “Vanadium is found around the world but in dilute amounts, and extracting it is difficult,” says Rodby.

Do flow batteries degrade?

That arrangement addresses the two major challenges with flow batteries. First, vanadium doesn't degrade. “If you put 100 grams of vanadium into your battery and you come back in 100 years, you should be able to recover 100 grams of that vanadium—as long as the battery doesn't have some sort of a physical leak,” says Brushett.

Is vanadium a sustainable solution?

US Vanadium can recycle spent electrolyte from VRFBs at a 97% vanadium recovery rate. This makes the VRFB a truly sustainable solution – the vanadium resource is only being borrowed from future generations, not consumed at its expense. One of the main costs affecting vanadium electrolyte is the price of moving it.
