Green electricity is both cheaper and much more available. Green H2 is inherently at a price disadvantage compared to green electricity. Unless absolutely unavoidable (as with steel or fertilizer production), why would you use it for anything?

Maybe I am looking at this from too much of a European perspective, i.e. on average, the grid is stronger here than e.g. in the US – but I don’t see going off-grid as a major factor either. If you can, you generally avoid going off-grid intentionally, because it’s just extremely expensive. Even if you’re planning for natural disasters, I see going with grid-connected, off-grid-capable solar as a much better idea, at least for most of the year.
