Sierra Space, a leading commercial space and defense technology company, has announced a strategic collaboration with Honda and Tec-Masters to advance clean energy solutions through space-based innovation. The partnership will focus on testing Honda’s high-differential pressure water electrolysis system aboard the International Space Station (ISS), a pivotal step in developing regenerative fuel cell technology to support long-duration space missions and future lunar habitation. The test is part of Honda’s broader vision to create a circulative renewable energy system that continuously produces oxygen, hydrogen, and electricity for sustainable human life in space.
Sierra Space will serve as the mission manager, coordinating closely with NASA and the Center for the Advancement of Science in Space (CASIS) to deliver the experimental payload to the ISS aboard its revolutionary Dream Chaser® spaceplane. With over 6 tons of cargo capacity and the ability to return payloads to Earth under gentle conditions (<1.5g’s), Dream Chaser provides a unique and versatile transport solution. Tec-Masters, Inc., with its extensive expertise in ISS payload integration, will lead technical payload certification and integration.

“The future of innovation in space is not only commercialization, but teaming arrangements between like-minded companies to advance technology we never thought imaginable in previous decades,” said Ken Shields, Sr. Director of Business Development at Sierra Space. “As we prepare for our first Dream Chaser mission to the International Space Station, this new collaboration with Honda and Tec-Masters is an additional proof point to the varied applications of our spaceplane to provide commercial transport to the space station and beyond.”
By bridging space-based research and terrestrial energy needs, this partnership exemplifies how advanced aerospace technologies can deliver scalable, sustainable solutions both in orbit and on Earth.
