The big problem is that fueling with liquid hydrogen is not easy. Getting things down to that temperature is not easy. Getting hydrogen cleanly is not easy. I mean if hydrogen was just as abundant in the atmosphere as oxygen and didn’t need to be at ridiculous temperatures to be liquid, it would be a great fuel. But to keep things green you’re fighting a ton of trade-offs using electricity, it which point why don’t you just use the electricity directly?
