Vanadium redox flow batteries. The other major battery technology that''s poised to make waves in grid (and potentially home) storage is vanadium redox flow batteries (VRFBs). VRFBs use vanadium in the electrolyte solution and do not require critical minerals such as nickel or cobalt that could be expensive or have constrained supply chains.

vanadium flow battery would have to increase to more than 25 years, due to the high costs of vanadium (vanadium costs = 60 – 80€/kWh).

As a result, vanadium batteries currently have a higher upfront cost than lithium-ion batteries with the same capacity. Since they're big, heavy and expensive to buy, the use of vanadium batteries may be limited to industrial and grid applications.

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.
And second, if some of the vanadium in one tank flows through the membrane to the other side, there is no permanent cross-contamination of the electrolytes, only a shift in the oxidation states, which is easily remediated by re-balancing the electrolyte volumes and restoring the oxidation state via a minor charge step.
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.
