Methane could be the fuel of the future for returning from Mars
"The setup is a CO 2/water electrolyzer," UCI physicist Huolin Xin, who is leading the research, told SYFY WIRE. "In a water electrolyzer, you have H 2 produced in the cathode and O 2 produced in the anode. In a CO 2/water electrolyzer, in the anode, O 2 is produced by oxidizing water. In the cathode, CO 2 is reduced into methane." Xin has developed the Organic Combustion Method, which is similar to the Sabatier process used to extract breathable oxygen from water on the ISS. The Sabatier process takes advantage of solar power to generate electricity that hits H2O molecules and triggers elec...
