- lukealization 2y agoWhy isn't SpaceX doing that then? Why isn't any airline doing that then? Oh look, it's cheaper to use refined natural gas from a well. That's why. In the absence of either properly priced externalities, the market will always choose the cheapest option—Sabatier-generated Methane is not remotely comparable in price to fossil nat gas. Mentioning theoretical solutions doesn't help if they will never be used practically.
- rstupek 2y agoI don’t think airliners use Methane?
- lukealization 2y agoAircraft use hydrocarbons which require similarly intensive chemical processes to create the fuels from the same constituent ingredients as the Sabatier reaction.
