If you are able to manufacture them in a completely emissionless way. That requires huge energy input though. Certainly has its uses, but too expensive for personal cars I'd think.
What I think would make sense is to use methanol as a seasonal energy store in temperate climates. Manufacture from PV in summer, burn in winter.
- coderenegade 1mo agoMethanol is the obvious choice, because there are so many ways to make it. Shipping certainly looks to be moving in that direction, though ammonia is also being trialled. Ethanol via fermentation is also doable at scale, but most effective pathways rely on using arable land.
- FabCH 1mo agoTo be fair, DIY natural gas production from kitchen waste is a thing some people have done. It’s surprisingly doable and produces surprisingly large amount of usable energy. It can be scaled up.
