WTF?! Hydrogen cell cars are even worse for the climate than gasoline cars! Less actual CO2 but way more in terms of equivs (methane is a 🐝 and a half).
All cars are bad but battery electric are currently least bad.
@Sandra There is a big push to move to catalytic decomposition of water however, and in some regions that is the main production method. I know Europe is home to at least one company that does that, bit I don't know where they are based.
@Sandra Also, the fact you make the H2 from CH4 doesn't mean CH4 is released into the atmosphere; it just means that X mols of CO2 are, which isn't good, but it does avoid some of the nasty products that burning gas does.
But there is lots of research into clean H2 production. Not as much as there once was, due to lots of people switching over to battery research, but there are certainly applications for it, since you can refuel a truck more quickly then you can recharge a battery.
Though, swappable batteries would fix that problem, I've not seen anyone looking at that for cars.
@Sandra I expect they would have to treat that to make it CO2 due to how toxic CO is. CO is less of a greenhouse gas however.
@Canageek CO wants that extra O pretty badly and oxidises to CO2 pretty quickly (hours-to-days).
Which then leaves you with the usual problem of CO2.
CO in high concentrations is a problem. Those concentrations aren't found even relatively close to any fairly large fire in open space. A raging firestorm, possibly.
@dredmorbius @Sandra Yeah, I"m used to reading about it in cylinders and as a reagent, environmental chem isn't my thing.
@Canageek or rather CO with only one O 💔 I hope they do send their numbers next week!
