The solution to power outages during the Moon\u2019s 14-day-long, freezing nights may lie in Honda’s regenerative fuel cells<\/strong>. Honda<\/strong> will collaborate with Astrobotic<\/strong> for this lunar project<\/strong>.<\/p>\n\n\n\n

With both NASA<\/strong> and the Chinese space agency<\/strong> preparing for crewed missions to the Moon, significant steps are being taken toward establishing permanent lunar bases<\/strong>. However, many challenges still need to be resolved before these grand plans can be realized. One of the most pressing is the Moon’s approximately 14-day-long nights<\/strong>. During these extended periods of darkness, temperatures can plummet to as low as \u2212253\u2218C (\u2212423\u2218F)<\/strong>, rendering solar panels<\/strong> inoperable. Therefore, providing uninterrupted energy<\/strong> on the Moon is a critical requirement for any permanent base.<\/p>\n\n\n\n

The technology that could address this challenge may be hidden within Honda’s regenerative fuel cells<\/strong>. Seeking ways to adapt this technology for space programs, Honda<\/strong> is entering into a collaboration with the US-based company Astrobotic Technology<\/strong>. The two companies aim to integrate Honda\u2019s regenerative fuel cell technology<\/strong> with the power infrastructure Astrobotic<\/strong> is developing for the lunar surface, thereby creating an energy source that can endure the Moon’s long nights.<\/p>\n\n\n\n

Honda and Astrobotic to Develop a New Energy System for the Lunar Surface<\/h2>\n\n\n\n

Honda’s<\/strong> developed regenerative fuel cell system<\/strong> is fundamentally based on a two-stage cycle. During daylight hours, electricity generated from solar panels<\/strong> is directed to an electrolyzer<\/strong>, where pure water is split into hydrogen<\/strong> and oxygen<\/strong>. The hydrogen<\/strong> is stored in high-pressure tanks or alternative storage methods, while the oxygen<\/strong> can also be stored as needed. Once night falls, these two gases are recombined in the fuel cell<\/strong> to generate electricity. The resulting byproduct, water, is purified and fed back into the system. This closed-loop cycle<\/strong> creates an energy model capable of continuous operation.<\/p>\n\n\n\n

However, for the system to be viable in lunar conditions<\/strong>, it must be made vacuum-sealed<\/strong>, resistant to extreme temperature variations, and protected against lunar dust<\/strong>. Furthermore, the volume and mass issues created by the need to store hundreds of kilograms of hydrogen<\/strong> must also be resolved. The newly established partnership with Astrobotic Technology<\/strong> will pave the way for adapting this technology to lunar conditions<\/strong>.<\/p>\n\n\n\n

These fuel cells<\/strong> will be used in conjunction with Astrobotic’s Vertical Solar Array Technology (VSAT)<\/strong>. This sun-tracking system currently generates 10 kilowatts<\/strong> of power, but the company is also working on a larger version that will reach 50 kilowatts<\/strong> of capacity. Honda’s<\/strong> technology will make the energy stored during the day available throughout the lunar night<\/strong>, ensuring a continuous flow of power.<\/p>\n\n\n\n

The system’s most significant advantage will be the elimination of the need for external resupply. This will ensure energy security<\/strong> for long-duration missions, enabling bases to operate not just for days, but for months, or even years. Bobby Rolley<\/strong>, Astrobotic’s Lunar Power Systems Architect, described the partnership as a “revolutionary step<\/strong> that will enable sustainability in the harsh lunar environment.”<\/p>\n\n\n\n

The partnership will first involve a comprehensive feasibility analysis<\/strong>, focusing on three main areas: simulating one-year sunlight profiles at potential deployment sites on the Moon’s South Pole<\/strong>; assessing how the fuel cell<\/strong> can be scaled for different mission sizes; and testing the integration of Honda’s cells<\/strong> with Astrobotic’s<\/strong> hardware and software infrastructure.<\/p>\n\n\n\n

If the system works as expected, it will be able to power life support units<\/strong>, scientific instruments, communication infrastructure, and robotic systems without experiencing power cuts throughout the Moon’s long nights. Since Honda’s Space Development Division<\/strong>, established in 2024, is already working with NASA<\/strong>, Honda’s fuel cell technology<\/strong> will also be used in NASA’s projects<\/strong> if it proves successful.<\/p>\n\n\n\n
