Vanadium batteries rival lithium-ion

Global industry ramps up as VRFB appeals to grid renewables

Solar and wind renewables can generate very cheap electricity, but like good weather, they're intermittent. To achieve a green-energy future of grids running off renewables, enormous amounts of battery storage will be needed to avoid blackouts.

The first redox-flow batteries were developed by Lawrence Thaller and his group at NASA in the...
