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. In this project, we will do a thorough analysis of levelized cost of hydrogen produced using various high temperature electrolysis processes such as the solid acid, molten salt and solid oxide electrolysis technology. We will then proceed to build, analyse and demonstrate a single cell, high temperature electrolytic cell of the chosen technology.
