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.
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?
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
Good. Waste of time and money. It's wasteful. Only 30 – 40% of the original energy used to make the hydrogen makes it to movement. Or worse depending on storage and transport times. The only reason it's getting attention is the fossil fuel industry pumping money into the idea to sell blue hydrogen until green is cheaper. But green will never be cheap as it's so a wasteful use of energy.
