Vanadium flow batteries are considered a leading light of the push towards technologies that can meet the need for long-duration energy storage. Not least of all by the companies that mine the metal from the ground. Andy Colthorpe learns how two primary vanadium producers increasingly view flow batteries as an exciting opportunity in the energy transition space.
A framework agreement for the deployment of 2GWh of iron electrolyte flow batteries has been signed between manufacturer ESS Inc and SB Energy, the clean energy arm of Japanese telecoms giant Softbank.
US Vanadium, which counts high purity electrolyte for flow batteries among its range of vanadium products, has said it will expand its annual electrolyte production capacity to 2.25 million litres a year in response to demand.
