So how long until one of those blows up? No matter how good the insulation, cryogenic hydrogen needs cooling to stay stable. You can’t just put it in a tank and store it for extended periods of time.
Portable to me implies that it’s not cryogenic or else it would have to let the hydrogen boil off and can’t do long term storage.
So either these are room temperature and rely in unspecified magic to store the gas, or they’re short term only and require a truck based delivery/recycling system.
