Honda and Astrobotic Establish Joint Development Agreement to Explore Scalable Lunar Power Solutions

TORRANCE, Calif., and PITTSBURGH, September 29, 2025 – American Honda Motor Co., Inc. and Astrobotic Technology, Inc. today announced a joint development agreement aimed at developing a scalable and integrated power solution for sustained lunar surface missions. The joint feasibility study will explore how the Honda regenerative fuel cell (RFC) system can be integrated with Astrobotic’s Vertical Solar Array Technology (VSAT) and LunaGrid service to provide continuous power, even during prolonged periods of darkness on the Moon.

The Honda RFC system, known as a circulative renewable energy system, is designed to continuously produce oxygen, hydrogen, and electricity using solar energy and water. During the lunar day[1], the RFC system stores solar power as hydrogen and converts it into electricity during the lunar night[2].After generating electricity, the only byproduct of the fuel cell is water, which is recycled into the Honda high-pressure water electrolysis system to create a closed-loop energy cycle.

Astrobotic is creating a scalable power infrastructure service, called LunaGrid, designed to supply sustained lunar surface power for a wide range of lunar missions and customers. A key component of LunaGrid is the Astrobotic VSAT, a solar-powered system that is deployable, self-leveling, and capable of sun tracking for optimal energy capture. Astrobotic is developing a 10 kW VSAT system, along with the Extra-Large Vertical Solar Array Technology (VSAT-XL), which would generate 50 kW of power to support the growing power requirements of planned lunar missions.
