Hydrogen requires minimal modifications to gas turbines, notably the combustors need to be swapped out.
Storage and distribution works the same as for fossil methane (pressurized in cave systems/old gas wells).
Production is simple, and we yes, the efficiency is around 20-30% round-trip.
But that's enough to handle up to ~30% of electricity supply with less than 2x overcapacity.
And that's assuming you don't just slap carbon capture on a gas turbine you feed with fractionally distilled oxygen (>99% should be easily enough) and enough exhaust back-feed to not melt the turbine blades. A diesel would probably deal better with the combustion temperatures, though.
And Fischer–Tropsch can turn captured carbon into piston-engine-suitable liquid fuel, if you'd need to.
