RFC Power are developing new classes of low-cost redox flow battery chemistry, leveraging concepts from fuel cells.
Energy storage is a critical component of the transition from conventional fossil fuel generation to a low-carbon energy system dominated by variable renewable generation such as solar and wind. Redox flow batteries are a form of rechargeable battery ideally suited for long duration, stationary energy storage but uptake of current technologies, such as all-vanadium systems, is limited by electrolyte cost.
RFC Power’s patented hydrogen-manganese system combines optimised cell architecture with low-cost chemistry. The system has a high single cell voltage, high power density, high round trip efficiency, extremely long cycle-life and crucially capital costs which are a fraction of competing flow battery systems as the electrolyte is based on inexpensive, non-toxic abundant materials.
