Hydrogen storage is difficult only in metal tanks at high pressure and temperature. Store it underground or liquify it, and the problem dissipates.

Heating and lamp gas composed of of hydrogen and carbon monoxide (!) were once delivered throughout cities through cast-iron plumbing. That was displaced by "natural gas" as increasing numbers of people were found to have been asphyxiated after a lamp flame in their house died, typically from a pressure fluctuation.

Natural gas then had to have mercaptan odorants added after leaking gas accumulated undetected and exploded. Then, valves that would only stay open when hot came into regular use, for pilot lights. Now pilot lights are gone, replaced by spark generators. Hydrogen will displace natural gas in industrial settings, but synthetic methane or propane will probably be needed for domestic use.
