I’ve said it before and I’ll say it again: most new hydrogen technology is snake oil.
Its main source right now is as a byproduct to petrochemical processing, so a lot of the motivation behind it is really about maintaining these production lines, rather than “going green”.
Some things do require hydrogen, eg science applications. Hydrogen can be made using green electricity, but the energy cost is incredibly high. In order to fulfill just the things that require hydrogen, where there is no other alternative, we would need 3x the global renewable capacity solely dedicated to hydrogen production. If we start adding mass transport into that mix, or things like this hydrogen heating system, then we’re only exacerbating the problem.
We need our renewable electricity to power things that already use electricity. We don’t have enough capacity to be pouring it away into all the potential uses for hydrogen - which are often far less efficient. You lose so much energy creating hydrogen (as well as losses due to leaks) that you may as well just power it with electricity directly.
Lol you caught me out, I skimmed over most of the article. I’ve also realised later down the thread that one of my main sources actually includes hydrogen for heating as a viable use case.
I still stand by my claim that most hydrogen consumption proposals are snake oil, which would be better served by using electricity directly (particularly in transport), but perhaps this could be good.

There could not have put up a bigger sign saying, “I didn’t bother to read the article.”
Otherwise I don’t disagree with most of what you’re claiming. But most of the problems you posed do not even apply to this relatively new system.
