High temperature electrolysis
Water electrolysis is a key technology for hydrogen generation with low-carbon intensity. Water electrolysers use renewable electricity to split water into its elemental components. However, the low temperature electrolysis technologies (80 °C) face a steep challenge as they have a very electrical energy consumption. Performing electrolysis at higher temperature (300 to 800 °C) leads to lower electrical energy consumption as rest of the energy can be supplied in thermal form using waste heat from industrial process.
