While lithium batteries have taken center stage for energy storage, vanadium redox flow batteries could gain considerable traction in 2020. In previous years, vanadium battery installations around the world have done little more than provide proof of concept and a test bed for manufacturers, argues David Gillam from Mastermines. He looks at what may have changed since then and why a surge in batteries utilizing vanadium may be closer than many believe, with China taking the lead.
Vanadium flow batteries have teased both stakeholders and the new energy market in general so far. What should not be in dispute is that they are unique. They offer many advantages over lithium batteries, beginning with a lack of complexity that translates to impressive stability. In addition, they may be fully charged and discharged without damage and they can operate safely in a wide range of ambient temperatures. Add a relatively simple cell stack design and a more fitting description may be to tag them as long-lasting “energy machines” rather than batteries.
