if you had a household unit that produced hydrogen for energy storage (from eg. solar from your roof) in principle you could also concentrate oxygen, maybe for medical use, or maybe even just to oxygenate a room. would that be desirable enough to come in handy next resp pandemic?

Would it be energy efficient or would you be paying to provide the service?

Also, hydrogen is super volatile, which is half of the expense.

the idea would be this is a value add on top of a hydrogen long term energy storage for backup or for rather large cyclic demand / supply mismatch like solar roof microgrids or whatever

Wouldn't using the solar energy to fill batteries be cheaper, safer, and more energy efficient?

well, not for long duration, no, not cheaper. you have a major (order of magnitude) difference per marginal kwh of hydrogen vs batteries. it is less efficient, so if it only makes sense when solar / wind really has declined massively in cost and is in high penetration.

but, safer? maybe. maybe not?? (but probably yes, and batteries and bms have gotten much better)
