It works, but you loose some more energy. Better still is to make fertilizer with that and ship that out. Shipping ammonia half way around the world with the intention of using it as a fuel doesn't make sense from an efficiency point of view. You loose so much energy creating the hydrogen, transforming it into ammonia, shipping it around, and then turning it back into mechanical or electrical energy, which again is not super efficient. By the time that is done, you are looking at maybe 10% efficient (possibly way less). So, it's a very costly way to move stuff around using ammonia as a fuel. Nice that it works but unlikely to be a preferred solution aside from some niche use cases. And while ammonia is better then hydrogen in terms of volumetric density. It's still about half of what lng gives. So, you need two ammonia ships for every lng ship to deliver the same amount of energy. That same property also is an issue with bio kerosene vs. ammonia in planes.
