Vanadium Redox Flow Batteries

PNNL has designed and is testing a modular 1kW/1kWh vanadium redox flow battery with an optimized stack design. The battery incorporates PNNL’s new electrolyte chemistry, delivering 80% increased power capacity, 90% increased efficiency with about half the operating cost of current vanadium redox flow batteries. The battery also has greater operational temperature range, broadening the potential application scope and potential to store large amounts of energy from renewable yet variable resources, such as solar and wind.
