What is a vanadium redox flow battery (VRFB)?

The vanadium redox flow battery (VRFB) is arguably the most well-studied and widely deployed RFB system. At the time of writing, there are approximately 330 MW of VRFBs currently installed around the world with many more systems announced or under development, including a 200 MW/800 MWh plant in Dalian, China [15, 16].

How do you rebalance a vanadium tank?

Full rebalancing requires charging 1.5 moles of electrons per mole of vanadium for the entire tank volume, while partial rebalancing only requires recharging the ions from the partial volume mixing.

How much does a vanadium pentoxide cost?

For leasing to be an attractive option as compared to upfront purchase, vanadium prices must be sufficiently high and/or annual fees must be suitably low. At the time of writing, the price of vanadium pentoxide is ca. 16 $ kg −1 , which corresponds to 29 $ kg −1 of vanadium.

Where is vanadium used?

Vanadium use is primarily limited to a single market, the production of steel, which accounts for about 90% of demand, and only China, Russia, and, most recently, South Africa are major exporters .
