Comment on Chinese EV maker BYD says new fast-charging system could be as quick as filling up a tank
minkymunkey_7_7@lemmy.world 3 weeks agoI think Toyota and Honda… maybe somebody else was developing a Hydrogen cell car. I remember seeing James May on Top Gear talking about it and driving it. It was in California. It seemed really promising and very exciting at the time that’s why the memory imprinted on me a bit.

Toyota at least was getting their hydrogen from natural gas which rather defeats the whole point really.
In order for hydrogen power to be sustainable it has to come from electrolyzing water. But the power requirements are prohibitive since the process is unimaginably inefficient. Something insane like 80% of the power goes to waste when converting water into hydrogen and then you’ve got to find a way of compressing that hydrogen and transporting that hydrogen.
I’m not saying it’s impossible but in a world where you can recharge an electric car in 5 minutes what’s the point in even going to the effort of solving those problems.
