This all sounds excellent, but I'm wincing at how many different pieces there are that are either (a) semi-unproven or (b) have a really high capital cost to value ratio. And they all have to work for the business to work.

> H2 electrolyzers

Do you have a platinum-free solution for this?

> small haber-bosch plant

Is this a thing already? Wouldn't this be more directly marketable into the fertilizer industry, which needs fewer of the rest of the pieces?

> is only used as a "joker" a few days per year

This is very bad for capital efficiency, sadly.

why not rely on the grid those few days in a year? I kind of get self sufficiency is the goal, eventually, but for now sounds cheaper to go gradually?
