Traditionally, much of the global vanadium supply has been used to strengthen metal alloys such as steel. Because this vanadium application is still the leading driver for its production, it’s possible that flow battery suppliers will also have to compete with metal alloy production to secure vanadium supply.
In order to increase the energy content of the flow battery, the additional active material and the tank are required, so that the cost proportion of the electrolyte may increase depending on the storage capacity increase and the fluctuation of vanadium market price.
