When you say "electrochemical CO2 reduction", can you expand a bit more into what that method is?

Either a methane or carbon monoxide fuel cell run in reverse, or using hydrogen to water gas shift and then further reverse steam reforming into methane.

When you add an initial water electrolysis to the sabatier process you can have
H2O + CO2 > O2 + CH4
That is water and carbon dioxide in, oxygen and methane out. Good for life support in space. If you had infinite free energy you can easily synthesize methane out of air and water.
