Redox flow batteries, and to a lesser extent hybrid flow batteries, have the advantages of: • Independent scaling of energy (tanks) and power (stack), which allows for a cost/weight/etc. optimization for each application• Long cycle and calendar lives (because there are no solid-to-solid , which degrade lithium-ion and related batteries)

Will flow battery suppliers compete with metal alloy production to secure vanadium supply?
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.

What chemistries are used in redox flow batteries?
Traditional redox flow battery chemistries include iron-chromium, vanadium, polysulfide–bromide (Regenesys), and uranium. Redox fuel cells are less common commercially although many have been proposed. Vanadium redox flow batteries are the commercial leaders.
The zinc–bromine (ZBRFB) is a hybrid flow battery. A solution of is stored in two tanks. When the battery is charged or discharged, the solutions (electrolytes) are pumped through a reactor stack from one tank to the other. One tank is used to store the electrolyte for positive electrode reactions, and the other stores the negative. range between 60 and 85 W·h/kg.
