But it depends where the hydrogen comes from though. (I can’t view the article as it doesn’t like my ad blocker so apologies if it’s explained there).
Plus mains electricity can be green, windmills etc.
Anyhow, sorry to be pedantic.
@icanbob @minibyte interesting point that I hadn’t considered, thank you.
I suspect that with the right infrastructure catenary would still have the edge - it removes the weight of the battery/hydrogen plant from the train and there’s no reason you couldn’t have a static hydrogen plant feeding power to the wires. Wouldn’t that give a greater benefit? Also you can have a mix of power supplies which addresses the variability of supply, eg, solar, wind and nuclear.
