Honda Will Test a Fuel-Cell System in Space

IEEE Spectrum | Lawrence Ulrich | 22 Apr 2025

Elon Musk may have called dibs on Mars. But with an eye toward life on the moon, Honda will test a new regenerative fuel-cell system aboard the International Space Station( ISS).

The test will build upon research from Honda’s earthbound hydrogen cars like the Clarity and new 2025 CR-V fuel-cell SUV, which use a circulative renewable-energy system. The system will produce a continuous stream of oxygen, hydrogen, and electricity on the ISS—or, someday, perhaps a moon base.

On 4 April, Honda announced it would test its high-differential-pressure water electrolysis system on board the ISS, although the company hasn’t yet revealed the launch date. The test will be part of a collaboration with Sierra Space, a Colorado-based commercial space company, and the Alabama-based aerospace company Tec-Masters.

Late last year, Honda established a new space-development division within its U.S. subsidiaryto develop technologiesand better collaborate with the U.S. space industry. Sierra Space will transport Honda’s system to the ISS aboard its Dream Chaser spaceplane. The 9-meter craft—about one-quarter the length of the retired space shuttle orbiters—can haul five tonnes of pressurized cargo and a half-tonne of unpressurized cargo, andthen land at any compatible commercial runway around the world.
