Summary: The major technologies for green hydrogen production are PEM and SOE. While PEM technology is being commercialized at MW scale, SOE technology is still under development at kW scale and higher costs. SOE has the potential to reduce energy input by up to 30% for hydrogen production by utilizing low-cost thermal energy. The search for alternative cathode materials for SOE is ongoing, and nanoengineered materials synthesized using infiltration and exsolution techniques show promise. Techno-economic analysis is required for the commercialization of these materials in SOE.
