Honda Motor Co. and Astrobotic Know-how have entered a joint growth settlement to research scalable lunar energy options that mix Honda’s regenerative gas cell (RFC) system with Astrobotic’s Vertical Photo voltaic Array Know-how (VSAT) and LunaGrid service. The collaboration goals to ship steady and dependable energy for prolonged lunar floor operations, notably in the course of the two-week lunar night time.
Honda’s RFC system, a circulative renewable power cycle, makes use of photo voltaic power and water to supply oxygen, hydrogen, and electrical energy. In the course of the lunar day, solar energy is saved as hydrogen, which the system converts again to electrical energy at night time. The method yields water as the only byproduct, which is recycled into Honda’s high-pressure electrolysis system to shut the power loop.
Astrobotic’s LunaGrid service is being developed as a modular energy infrastructure for a broad buyer base. At its core is the deployable, sun-tracking VSAT. Present designs embrace a ten kW VSAT system and a bigger 50 kW VSAT-XL to satisfy rising energy wants for future missions.
The feasibility research will goal three essential objectives: assessing illumination situations at potential LunaGrid websites, evaluating the scalability of Honda’s RFC system, and defining integration necessities between Honda and Astrobotic {hardware} and software program.
By pairing the RFC with VSAT, Honda and Astrobotic count on to make sure uninterrupted power provide throughout lunar day-night cycles. This functionality would improve mission resilience, assist everlasting human presence, allow infrastructure building, and open alternatives for lunar industries.
As a part of the research, each corporations will mannequin one-year photo voltaic illumination profiles at candidate South Pole touchdown websites. Simulations will information the scaling of the RFC to match the power storage wanted for numerous mission architectures, guaranteeing adequate energy for electrolysis and sustained nighttime electrical energy.
