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?
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

The question I pose is, "after factoring costs, even using solar energy, is harvesting hydrogen lucrative and safe?"
-
depends on the level of solar penetration; should be vastly more if we reach 1/2 by 2030

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.
