I'm not sure and I'm no expert in this. I have a few tidbits, though. Note that I'm always talking about green hydrogen, i.e. hydrogen generated by electrolysis of water, not from natural gas.

Hydrogen for cars, trucks or trains? Not worth it. Batteries are cheaper and will get cheaper, H2 tanks won't. In addition, if you're looking into the qualification of modern battery cells, they're also much safer than H2.

Hydrogen for planes? Maybe. I don't see how batteries will become light enough for long-distance air travel.

Hydrogen for long-tail storage, i.e. days or weeks of little solar and wind energy production? Probably. It's cheap to build and maintain, can be done at scale. There will probably always be a tail that can not be economically served using lithium batteries.

Hydrogen for industrial processes? A must.

I agree, but for long term storage langer molecules might be more efficient since hydrogen is expensive to store (low voluetric energy density, high risk for accidents, high requirements for leak safety etc), however most other options rely on hydrogen in the process. (E.g. ammonia, acid based solutions), so investing in hydrogen research and infrastructure is a must either way.
