🇨🇳🌌 Chinese Scientists Develop Catalyst to Turn Martian Carbon Dioxide Into Fuel Chinese scientists have developed a catalyst that could help future Mars crews make fuel from local resources, cutting the amount they would need to bring from Earth. In laboratory tests, it helped turn carbon dioxide and hydrogen into methanol, a liquid fuel that could also supply the ingredients for everyday chemicals. Researchers at the Deep Space Exploration Laboratory in Hefei combined copper and sodium inside a porous crystal. The sodium helps grab carbon dioxide and makes it easier for the copper to do its work, producing more methanol and less unwanted carbon monoxide. The combination delivered about 11 times the methanol output of the team’s copper-only comparison catalyst, reaching 245 grams per kilogram of catalyst per hour. That gives researchers a promising material to work with, although a successful lab test is still some distance from a fuel plant astronauts can plug in on Mars. With carbon dioxide making up more than 95% of its atmosphere, Mars has no shortage of the main ingredient. Hydrogen could be extracted from its water ice. Getting both into a reactor would require mining equipment, gas collection, compression and plenty of energy. The ingredients may be local, but the fuel will not make itself. Methanol’s appeal is partly practical housekeeping. It stays liquid at ordinary room temperature and pressure, while storing methane as a liquid requires extreme cold. Methanol would still need proper storage on Mars, but avoiding that deep freeze could simplify part of a future base’s fuel system. The team sees possible uses in electricity generation, heating and rover power, with methanol also serving as a starting material for products such as antifreeze. Making one useful chemical locally could therefore trim several items from the cargo manifest. The research does not yet demonstrate rocket propulsion or a complete production system. For China’s long-term exploration ambitions, that is the attraction of learning to live off Martian resources. If the process can run reliably at useful scale, future crews could replenish some supplies where they work. Every shipment of fuel or chemicals they no longer need from Earth would free cargo space for tools, scientific instruments and equipment to support longer stays. @NewRulesGeo❗Follow us on X
