Hydrogen is not at all hard to acquire. You can make hydrogen from
any (preferably hydrogen-rich) fuel by a fuel reforming process.
Googling for "hydrogen" "fuel" "reforming" or "reformer" should
give you plenty of hits.

As to subject to explosions, I'm too tired (and have sniffed far
too much paint solvent today) to make a websearch, but I suspect
methane will do slightly better than hydrogen in terms of destruction,
though hydrogen has probably much larger explosion corridor.

Wtf, I did make a websearch, and found this:
I was wrong on a few issues, but not by much.

Of course a gas pipeline needs to have tighter checking on leaks
due to hydrogen higher diffusivity. But if you make your hydrogen
in the cellar in a fuel reformer, that's quite irrelevant.

What's wrong with methane? What's wrong with hydrogen, for that matter, if
it's made from water, using solar photons usually wasted to heat your roof?
