Hydrogen leaks like crazy
It does not leak like crazy. I know because I have experience engineering and operating high pressure electrolysis, storage, and fueling systems for hydrogen. Even when it does leak, what's nice about hydrogen is that it's not toxic to humans or pollutive to the environment, unlike ammonia or fossil fuels. Hydrogen leaks are easily mitigated with proven detection and ventilation techniques.
I thought hydrogen could leak through containers? On account of being so small?
Hydrogen will leak through a latex balloon, but it is not going to leak through the steel wall of a pressure vessel. The leak risk occurs at the various fitting connections in a hydrogen system, which is overcome by using the proper fittings.
