If We Can Master Artificial Photosynthesis, We Can Thrive in Space universetoday storybywill
to provide a steady oxygen supply. This system relies on electrolysis, where electricity from the station’s solar panels splits water into hydrogen and oxygen gas.
Furthermore, the system would be easier to maintain since it would need less complex wiring and mechanical components. To test this concept, Dr. Brinkert and her colleagues produced a theoretical framework for measuring the performance of a PEC against a conventional BLSS. This included the efficiency of solar-driven water splitting, the available solar energy on Mars , and the reduction of CO2 in Mars’ atmosphere.
“Our analysis shows that these devices would indeed be viable to complement existing life support technologies, such as the oxygen generator assembly employed on the ISS. This is particularly the case when combined with devices that concentrate solar energy in order to power the reactions .” This proposed system offers numerous advantages over conventional electrolysis devices, which operate at high temperatures and require a lot of electricity. While NASA is investigating technology that could harvest oxygen directly from lunar regolith, this method requires very high temperatures to convert elemental oxygen into oxygen gas . On the other hand, PEC devices could operate at room temperature within Martian and lunar habitats, using water as the main resource.
