    Except you have that problem with everything that doesn’t somehow take power from a catenary or similar

    Energy density counts for a lot, which is another reason why H2 is a substandard fuel.

    Yes, when you do have problems, the fires are quite big, but it’s a rarity for problems to exist, especially with trains that are maintained to a much higher standard than your average car.

    The Indian rail network is not known for its high quality maintenance.

    That said, I’d trust anyone with batteries over hydrogen, as a general rule.

      Fair point about the Indian rail network

      Mind you, Hydrogen is actually less dangerous than batteries. When there is a leak, it generally dissipates fairly quickly and fires or similar are quite rare. So in that case… Maybe it would be better if the Indian railways used Hydrogen after all

        Tell that to the Hindenburg.

        When there is a leak, it generally dissipates fairly quickly and fires or similar are quite rare

        It’s more the risk of hydrogen embrittlement, which can cause sudden catastrophic failure of their containers.

        And, broadly speaking, it’s not an issue because hydrogen cells aren’t commonly in use for retail civilian consumption.

        As soon as you’ve got a bunch of big tanks zipping around on bumpy tracks at high speeds…
