The prospect of establishing long-lasting human habitats on the Moon has inched closer to reality, courtesy of a pioneering study published in the journal Joule on July 16, 2025. This innovative solar-powered technology—conceptualized by Lu Wang and her team at the Chinese University of Hong Kong, Shenzhen—leverages the Moon’s natural resources to extract water and convert astronauts’ carbon dioxide (CO₂) into both oxygen and fuel. This technological leap could minimize the need to transport vast amounts of critical resources such as water and oxygen from Earth, thereby making prolonged lunar missions more viable and financially sustainable.
Lu Wang’s research focuses on the immense potential of lunar soil in supporting future Moon habitats. By utilizing naturally occurring materials on the Moon, her team devised a method that performs water extraction and CO₂ transformation via a groundbreaking photothermal strategy. This approach not only boosts energy efficiency but also simplifies the required infrastructure for potential lunar bases.
The implications of this technology are substantial. Currently, sending water to the Moon costs an estimated $83,000 per gallon, with astronauts needing approximately four gallons daily for just their basic needs. The logistics of supplying enough resources for a lunar colony is daunting, but effectively using lunar resources could entirely shift space exploration dynamics.
Through samples procured during the Chang’E-5 mission, Wang’s team successfully demonstrated their system’s capacity to extract water and utilize a novel light-concentrating process to transform CO₂ into carbon monoxide (CO) and hydrogen. These elements are further processed to produce both fuels and breathable oxygen, essential for human existence on the Moon.
Nevertheless, practical application of this promising technology still encounters hurdles due to the Moon’s harsh environment—marked by extreme temperature changes, intense radiation, and varying lunar soil properties. Additionally, scaling up CO₂ conversion to levels supporting human life sustainably remains a significant challenge.
Despite these obstacles, the continuous refinement of this technology brings us closer to a future where humans might inhabit lunar bases indefinitely, using the Moon as a launchpad for deeper space exploration.
