Personally I think the solution for planes is the one noone wants to hear :( We just need to fly a LOT fewer planes. Electric for short flights possibly but even then with the charging time the uptime on those is pretty bad compared to burning carbon and probably always will be. So… more electric trains? Pretty please?
compared to…?
Just batteries or running electrical cables next to the rails
The only benefit hydrogen has is its reduced weight, but when that isn’t important it’s easier to use other energy storage and delivery methods.
I can’t imagine it’s got a weight advantage over just running cables like they already do.
Not for trains, no. But for planes or space rockets it’s relevant.

I agree we need to fly less, but we won’t be able to eliminate it, so I think it’s one of the tools we’ll need in our toolbox
