short version:
>hydrogen has very low density -> hard to pump a lot of it -> low thrust
>need huge tanks to carry enough of it
>hydrogen must be cooled within ~30k of absolute zero and must stay that cold. Requires heavy (again) insulation
>it's also crazy expensive
>it's also all-round inferior to sub-cooled methane lol

shorter version: NEVER USE HYDROGEN AS A BOOSTER FUEL
