Leaked hydrogen, all told, traps 200x as much heat as CO2. We really should not leak any more than we must. By itself, it is just 6x. But it has lots of other interactions, such as increasing lifetime of methane. But round-trip efficiency of hydrogen will be rising fast. Electrolysis by itself, which used to be 60%, will go well over 90%, maybe over 95%, in short order.
