I don’t think anybody has failed to notice this. Toyota and Honda have both had notable failures bringing Hydrogen fuel cell cars to market despite exciting claims along those lines. I think you’ll have to quote some more authoritative sources to convince people that it could be viable.

This ignores the part where battery powered cars have existed for over a century and have "failed." But recent events have changed the needs of society, and now they have "succeeded." People are now claiming that this can never happen again or that no innovation is possible in the future for another type of battery chemistry.

  The needs of society changed but so did the technology. An EV built in 2020 is a completely different proposition to one built in 1990. > People are now claiming that this can never happen again or that no innovation is possible in the future for another type of battery chemistry. Who is claiming this?

    And a fuel cell car today is completely different than one built in 1990 too. > Who is claiming this? You are claiming that. You seem intent to not accept the fact that hydrogen fuel cells are a form of battery technology that can advance.

      I have not said that. I have asked what the avenues of research are that suggest that there are major advancements to be made and are underfunded.

        It is literally a battery chemistry. It should have broadly the same properties as li-ion batteries. There should not be any challenges, at least not ones that can't be solved via just spending more on R&D. Not to mention that you are consistently implying that this must somehow come at the exclusion of progress anywhere else. That is an absurdity. The point is that we should take this idea seriously alongside other ideas.

        My point is the idea is taken seriously and there is already funding and research applied to it.

        Clearly not, since the original article didn't even mention it and very few in the comments section brought it up either. It is seriously being ignored in a real way.

      Fuel cells is not a problem. Hydrogen storage is. Hydrogen is just a very nasty material, it leaks through everything, makes steel brittle and requires extreme pressures to store it at meaningful density. Combine the last two problems together and it's easy to see why there are significant technological barriers to hydrogen adoption.

        And lithium is somehow easy to deal with? This is really just another excuse. The point wasn't claiming those problems don't exist, it is asking why we are not seeing those problems as motivation for massive R&D spending in order to solve them.

Cars are most likely the wrong application for the technology given it's explosive potential. Grid connected or off grid storage seem like a far more apt use for the tech.
