I think you’re being a little too generous; the only use-case where I’m aware of it being optimal is rocket fuel. Trucks retain their fuel for long enough that storage and leaks become a problem unless you have impractically heavy tanks.
I think trains and excess generated wind/solar energy storage are also use cases.
I still think these strange sounding, deadend ideas (like hydrogen bikes) still have some use, because you don’t know what helpful discovery might be found, even in failure to accomplish the main objective of the project.
Hydrogen as a use case only works for already very heavy vehicles like trucks. Even for normal cars it’s a stupid idea.
Now using it for small mobility, thats maximizing idiocy.
