This is a solved problem, why do people persist with stuff repeated in the 1980s?!

There are endless h2 vehicles on the road. Do you think the tanks used, are apt to become brittle, and leak?!

There are h2 refueling stations for said vehicles, all over the place.

Do you think these leak, and become brittle?

And amusingly, your comment is redirecting from the claim that transporting h2 is hard. You are now poking at storage, instead of at transport (which can be done with pipelines, and is done with them).

In my case it's been at least a decade since I looked at materials science and hydrogen destroys steel isn't as well known as hydrogen blows up easily.
