Carbon dioxide electrolysis is an alternative path to creating hydrocarbons for a Martian settlement using In-Situ ressources.[1]

Rather than generating methane through Electrolysis of water and the Sabatier process, Carbon dioxide electrolysis in an aqueous solution using catalysts creates Carbon Monoxide (CO) and water (H2O).

The CO can be used to create feedstocks such as urea, formic acid, methanol, ethylene and methane.
