Because the goods made will be sold to American consumers directly and indirectly and are priced to reflect all kinds of costs including EPA compliance in domestic markets.
European markets also demand European norms to labour and health and environment are met, even if tokenistically. To some it is a form of protectionism.
It's also the "why can't we make it here" reasoning. If you tried to make it in the US it would be white anted out by lawfare. That's what happened to BHP when they proposed metals and minerals processing plants on the Californian coast.
Ammonia and hydrogen are essentially energy export mechanisms. They'll be exported to energy poor places, aka Asia, not America. they can and are made in America without fanfare. You wouldn't have states fighting to exlude green hydrogen or ammonia plants, you'd have states competing on how many subsidies they could give them.
Arguably, very likely true. But the fertiliser (the other ammonia product, the one we do mostly now the others being somewhat futurological) will I am sure sell worldwide. I'm personally sceptical about the hydrogen economy I can't see it working. It's biggish in some Australian circles, both because of IPR around the processes and people in related fields looking at uses for surplus solar power. Twiggy Forrest was big in it, wanted the sun cable proposal to pivot over, its partly why the JV with Cannon Brookes fell apart.
My comment was to the more general "why can't we have nice things" about industrial placement. I spent time in Culpeper and the number of "no more Datacentre" signs were amazing. Old folks who retired to the country don't want them build nearby. It's a large federal and private investment in tech services. And growing.
