Water electrolysis powered by renewable energies provides a means for green hydrogen production with minimal carbon footprint. Such green hydrogen is essential to reduce CO2 emission from hard to abate industrial processes such as oil refining, steelmaking and ammonia production, as well as an alternative fuel source and for renewable energy storage. Conventional water electrolysis operates in strongly acid or basic environments, utilizing membranes to separate the produced hydrogen and oxygen gasses. Consequently, the construction materials of the electrolizers are expensive and the assembly is complex, resulting in high-cost green hydrogen production. Aiming to solve these issues, decoupled water electrolysis where the hydrogen and oxygen evolution reactions are decoupled in time and/or space has emerged as an alternative approach to conventional water electrolysis. I present a new approach for decoupled water electrolysis using the bromide/bromate redox couple in an electrolytic – catalytic cycles that produces hydrogen and oxygen continuously in separated cells, without membranes.
