I think hydrogen does still have potential, just not for regular consumer vehicles. In cases where weight matters like flight, batteries just aren't near good enough now or anytime in the near future due to weight. In cases where you need monstrous amounts of energy between fueling/charging like ocean going cargo ships, batteries are again not anywhere near now or in the near future even close to sufficient. And in scenarios where there aren't safety concerns because consumers simply have no access to it and crashes/accidents are extremely rare, like with trains or large energy storage, hydrogen doesn't really have any real downsides compared to batteries but has plenty of upsides.

I still have hope for hydrogen fuel usage, but to me it has never made sense to try and push for consumer level hydrogen powered devices and cars. You can't just ignore an old hydrogen fuel tank in like an old junker car even if it is 99% empty, eventually that tank will pop and is a safety hazard. Where someone might accidentally damage or crash a vehicle with a hydrogen storage tank, it won't be just a localized fire, it is just a straight up massive bomb. And the extremely high pressures and/or cryogenic temperatures are not and never will be fool-proof enough for just the regular joe blow to have control over or easy access to it for refueling.
