- ryder9 6y agomethane isn't carbon neutral, what are you talking about also it's much much much much worse than carbon dioxide by itself at the greenhouse effect
- 0_____0 6y ago100% carbon neutral once fusion power makes the electricity needed to do air-to-fuel conversion basically free.
- DennisP 6y agoAny renewable or nuclear energy source would make it carbon neutral. It doesn't have to be free, the fuel doesn't cost that much in the first place, so a modest percentage cost increase is fine. We know that making the methane isn't super-expensive, because we've already used the Sabatier process commercially to make methane from CO2. That used carbon-based fuels to get the CO2; to really go carbon-neutral it'd have to be biofuel, or we'd need to pull CO2 from the air using direct-air-capture machines. https://en.wikipedia.org/wiki/Sabatier_reaction#Creation_of_synthetic_natural_gas https://en.wikipedia.org/wiki/Sabatier_reaction#Creation_of_...
