# Is production of methane possible on Mars?

${CO_2}$ is plentiful in Martian atmosphere. $H_2$ can be produced on Mars using sunlight and can be reacted with $CO_2$ to form $H_2O+C$, or $CH_4+H_2O$.

Is it a feasible chemical reaction?

• One has to either bring H2 from Earth or extract it from underground water ice which is much more laborsome to find and dig up than to just pump CO2 from the atmosphere. – LocalFluff Aug 10 '15 at 8:08
