    It’s also a tiny part of the market, because it’s literally 25x the cost of turning methane into hydrogen.

    Current electrolyzers are also much less energy efficient than batteries. It’s not an unsolvable problem, but battery tech is currently much more affordable than green hydrogen infrastructure. And an electrified third rail is a much better idea for trains.
