Honda, known for its expertise in hydrogen fuel cell technology, is embarking on a groundbreaking project to facilitate sustainable living on the Moon. The company's innovative approach involves the development of a circulative renewable energy system in partnership with US-based Sierra Space and Tec-Masters. Central to this system is a high-differential pressure water electrolysis system that continuously produces hydrogen, oxygen, and electricity - vital elements for supporting life in extreme off-Earth conditions. During the 14-day lunar night when sunlight is absent, Honda's regenerative fuel cell comes into play, using stored hydrogen and oxygen to generate electricity while ensuring a supply of oxygen for breathing. The leftover oxygen and hydrogen from the lunar day are then utilized by Honda's fuel cell system. The closed-loop nature of the system, which includes water recycling, makes it efficient and scalable for space and Earth applications. Honda plans to validate its technology on the International Space Station (ISS) in collaboration with Sierra Space, using the Dream Chaser spaceplane. This endeavor reflects Honda's vision for a regenerative fuel cell system that could revolutionize energy storage and sustain human life on the Moon. As part of this initiative, Honda established the Space Development Division to enhance cooperation with US space entities like NASA for upcoming lunar missions under the Artemis program.
