Honda is venturing into space with plans to test a renewable energy system on the International Space Station (ISS) to support sustainable human life on the Moon. Teaming up with Sierra Space and Tec-Masters, Honda aims to demonstrate that its system can provide continuous power and breathable oxygen in space using solar energy and water. At the core of Honda's innovation is a high-differential pressure water electrolysis system, producing hydrogen, oxygen, and electricity essential for life support on the Moon. The system will utilize solar energy during the lunar day to split water into hydrogen and oxygen. During the lunar night, the regenerative fuel cell will use stored hydrogen and oxygen to produce electricity, ensuring life support. Honda plans to recycle water produced as a byproduct back into the system, making it efficient and scalable. To test the technology in microgravity, Honda will conduct trials on the ISS. The lightweight and compact design of the system is ideal for space missions. The collaboration with Sierra Space and Tec-Masters showcases Honda's commitment to fostering a sustainable future through advanced technology. The project aligns with Honda's new Space Development Division, aiming to accelerate collaboration with U.S. space entities like NASA. By leveraging core technologies, Honda aims to support lunar missions under the Artemis program, enhancing its space ambitions and contributing to a sustainable future on the Moon.
