The engineering problem for wide spread use is hydrogen embrittlement.

For instance?

For instance the only existing distribution plumbing that will handle
hydrogen is on liquid hydrogen trucks; you can't run it down existing
gas pipe lines.

Hmmmm. I see that I should have asked rather "Of what?" (relative to
hydrogen embrittlement)

If you want to use hydrogen on a large scale, you have to have some
way to distribute it such as is done with natural gas. Huge fleets of
liquid hydrogen tankers isn't going to cut it.

Because of hydrogen embrittlement, any such distribution system will
have to be built starting from zero as no existing system can handle
hydrogen and building such a system will be both an engineering and
economic challenge.
