Honda to test clean energy system which could help sustain life on the moon
Honda has developed a high-differential pressure water electrolysis system aimed at supporting long-term lunar missions and sustainable energy use on Earth. The system forms part of a regenerative fuel cell capable of producing electricity, hydrogen, and oxygen continuously in space. This technology operates by using solar energy during the lunar day to extract gases from water, then uses those gases at night to generate power and breathable air…
