> readily available in the environment. That’s a red herring. Getting hydrogen and nitrogen out of their naturally occurring forms (bonded to other things or to themselves) and turning it into ammonia is very energetically intensive. > One scenario I can think of is using nuclear power on a platform in the ocean, manufacturing the Ammonia, ships can come by and refuel there. I can think of many such scenarios if money is no object. But as you say, they currently run on bunker fuel which is essentially garbage. You have to pay people to take that of your hands. It is being ridiculous to think that they would switch, on their own dime, to burning ammonia. And green ammonia at that which is orders of magnitude more expensive. Who is willing to pay the resulting shipping costs?
