High-temperature electrolysis

High-temperature electrolysis (also HTE or steam electrolysis) is a technology for producing hydrogen from water at high temperatures. Steam is dissociated to H2 and O2 at temperatures between 700 and 1000°C. n electrolysis, system efficiencies increase with increasing operating temperatures. Therefore HTE is known to be more efficient than the conventional electrolysis at room temperature.
