Re:Using copper to convert CO₂ to methane

AFAICT there are 3 broad steps for creation of "green" methane.
- creating H2 from H2O
- concentrating CO2 from either the atmosphere or the waste products of an industrial process such as cement production
- creating CH4 from the H2 and the CO2. AKA Sabatier.
This paper uses H2 as an input, so is only talking about the last step. A cheaper/better Sabatier is nice, but AFAICT it's the least expensive step of the three.
