So this is a pet peeve of mine. I can google that as easily as you can. But:

1. You made the claim. It's appropriate that you do the work to back it up.

2. A post is read more times than it is written. If you (the author) do the work, the work gets done once. If we, the readers, do the work, it's done multiple times.

So both efficiency and "burden of proof" say that you should do that search. In fact, you should have done it about 10 or 20 posts earlier.

You can just google it. Or bing it or whatever, since Google sucks these days.

It's happening everywhere now. Like I said, this is akin to someone demanding proof that there's war in Ukraine right now.

We're about 3 orders of magnitude away from green hydrogen being reasonably described as "at scale" at this point. It's roughly where PV was 15-25 years ago: nice to see the effort going on, but not at scale.

I would like to see some home system that makes and stores H2 with excess PV — such a thing certainly feels like it should be possible, given how easy hydrogen is to make, but I'm not a chemist or a civil engineer, so I'll leave that to those who know what can go wrong and how to fix it.
