Just as we put various odors in combustible fuels for safety reasons, the
same could be done for hydrogen, and a visual waveband emitting dopiant as
well

One thing that will probably keep natural gas as the fuel of choice is that
hydrogen will embrittle and ultimately make steel gas lines fail. Also,
hydrogen burns with a colorless flame (it does emit UV, that's how you can
detect a hydrogen fire) so there are safety concerns with piping the pure
gas around the country.
