When it comes to the economics of vanadium flow batteries, the dynamics of supply and demand for vanadium, the silvery-grey transition metal which when dissolved forms the electrolyte and therefore the key component of the battery, have long been the key talking point.
It’s likely you’ve already read many articles discussing the potential of vanadium redox flow batteries (VRFBs) to offer a long-duration, high energy counterpart to the high power, shorter duration capabilities of lithium on the power grid. Flow batteries decouple the energy and power components of energy storage systems.
In order to store electrical energy, vanadium species undergo chemical reactions to various oxidation states via reversible redox reactions (Eqs. (1) – (4)). The main constituent in the working medium of this battery is vanadium which is dissolved in a concentration range of 1–3 M in a 1–2 M H 2 SO 4 solution .
Flow batteries decouple the energy and power components of energy storage systems. That means you can scale up the amount of energy (kilowatt-hours, megawatt-hours) of a system with a set amount of power (kilowatts, megawatts), giving the opportunity to store several hours of energy.
