International Space Station Testing

Honda said it has developed an advanced water electrolysis system designed to support long-term operations on the Moon by prioritizing efficiency and reliability. The system’s lightweight and compact design addresses the critical need to reduce transportation costs in lunar development. Additionally, since it doesn’t use mechanical compression, maintenance needs are reduced, enhancing reliability for extended missions. By enabling high-pressure gas storage in smaller containers, the system also reduces the need to transport and manage large numbers of tanks.

“Honda will test the core part of its high-differential pressure water electrolysis system to verify the efficiency and reliability of the system in the microgravity environment of the ISS. For the ISS testing, Honda is collaborating with Sierra Space, a leading commercial space company at the forefront of innovation and the commercialization of space, and Tec-Masters, a leading provider of innovative scientific and technological solutions. Sierra Space will be the primary space mission integrator, working with NASA to transport materials on Sierra Space’s Dream Chaser® spaceplane, the world’s only commercial spaceplane. Tec-Masters will be the ISS technology expert,” Honda said.
