My intuition would be that it is overall cheaper in the long run to produce green hydrogen and build new or adapt existing plants so that they can consume hydrogen. Just a few percentage points in efficiency of the fuel generation would entirely negate any capital cost savings of reusing the old plants.

New gas turbines are able to generating electricity by burning hydrogen (up to 100%).

But there’s also utility gas. I wonder if hydrogen powered home appliances would be any good.
