Three innovations key to unlock green hydrogen – TotalEnergies

Electrolyser efficiency, solar-to-hydrogen and wind turbine integration are vital technologies to bring down costs of green hydrogen, oil major says

Three innovations are emerging to improve the long-term efficiency of producing green hydrogen, according to a new report from TotalEnergies. The first is the improvement of electrolysis technologies. Solid oxide technologies in particular are expected to bring a significant gain in efficiency, the report notes, though they are still at pilot phase. UK-based hydrogen technology developer Ceres Power recently announced its move into commercialising solid oxide electrolysis units. The second innovation is solar-to-hydrogen (STH), a technology with the capability of producing hydrogen directly from water and light, using panels combining photo-electrodes and electro-catalysts based on nanomater
