Hydrogen is too inefficient for homes, the better bet imo is a hard sell for induction cooktops. Hydrogen is just too hard to transfer (doesn’t compress nicely), inefficient to produce, and there’s going to be leakage issues.

It’s much better to produce that hydrogen very close to where it’ll be used. I’m imagining areas with lots of factories and whatnot producing hydrogen with excess solar and using it on site. The losses would be worth it because it’s probably cheaper than batteries (esp considering time to charge batteries, runtime of equipment, etc).
