Brief description This project aims to study and develop a highly energy efficient, fully reversible hydrogen-oxygen fuel cell - electrolyzer for energy storage. The core technology involves a very inexpensive three-phase (liquid-solid-gas) boundary that allows water to be converted into hydrogen and oxygen gas ('electrolyzer'), with separation and collection of the gases directly at source. Under optimum technoeconomic conditions, energy efficiencies of >90% are achieved. Similar efficiencies should be possible for the reverse reaction ('fuel cell'). If so, then this system may be used to store electricity as efficiently as the best current system, pumped hydro, which achieves 70-75% round-trip efficiency but requires large infrastructure.
