Except if you are pitching it as a solution for the base load problem - where is anyone doing solar+hydrogen at scale? Where is anyone committing to doing it at scale - let alone in the near future? How do we know it will remain economical at scale? All kinds of fun things can happen between theory/demonstration and implementation in the real world.

We do nuclear at scale today. The vast majority of blockers from doing more nuclear at scale today are political; not technical.

That’s the other facet of this that always seems to get overlooked.
