Mitsubishi Heavy Industries (MHI) has started operating a 400kW solid oxide electrolysis (SOEC) module, which has shown high levels of hydrogen production efficiency.
Based on the Japanese corporation’s solid oxide fuel cell (SOFC) technology, the 400kW electrolysis module is slated to operate at high pressures, which MHI said sets it apart from competing systems.
Comprised of 500 cell stacks, the SOEC system recorded electrolytic efficiency of 3.5kWh/Nm3 – representing a 101% higher heating value (HHV), according to MHI.
