> even the best available practical hydrogen storage tanks allow the gas to leak out at a rate of about 1 percent per day

Wow, I did not know that.

Really hard to keep a molecule that small in one place for long! I've definitely heard that it really just flies out of steel containers at shockingly high rates

It doesn't leak; it has to be vented. Hydrogen cannot be a liquid, no matter the pressure, at ambient temperatures, and there will always be heat leak. So your liquid hydrogen is always boiling, and with a good vacuum jacked dewar you'll lose 1-1.5% of the vessel's volume a day.

Also hydrogen has an indirect effect on climate.
