  • The fossil fuel industry is arguing for hydrogen because to keep costs down it will be made by natural gas reforming. Otherwise cost wise, putting 1 kWh of hydrogen into cars will be maybe 40% efficiency, then using fuel cells. So just multiply whatever your cost per electric kWh by 2,5. Hydrogen usable for stationary things like steel production though. Maybe methanol fuel cells are more viable idk

    Albeit this is just off the top of my head so it's not necessarily 100% correct. It is much more efficient to put electricity into batteries.

  • There's no skipping thermodynamics, maybe there will be a technology for an arbitrary molecule to hydrogen gas reformation but it doesn't exist to my knowledge. Electrolysis of water means breaking the bonds and that takes a lot of electrical energy.

  • Hydrogen is a horribly volatile compound, inherently unsafe. Regarding costs, I'll believe it when I see it.

    Besides there isn't enough of vital rare earths for the fuel cells. Currently it's a dead end.

    But do indulge me with links if you will

  • Problem is the total accumulated CO2 already there. We would need to be net zero yesterday to mitigate imo.

    Capitalistic institutions haven't been serious or motivated enough to make any real effort. They'll make up their next cop-out like carbon credits or whatever
