It's a great technology but as far as I can tell, ammonia is likely to be just another interim step to hydrogen.
Actually, ammonia is proposed as a transport medium for hydrogen, and in this regard the ammonia engine is really just delivering hydrogen power without the need to split hydrogen from the ammonia carrier as the pre-cursor process. Ammonia is easy to produce and transport, but once large scale hydrogen production gets underway ammonia will also become redundant, there will be no point consuming energy to create ammonia as the intermediate process from something like hydrogen sourced from seawater.
Perhaps ammonia is a great interim process for the hydrogen from coal process, which has some merit as an interim technology. I believe the Japanese are heavy into R&D in this regard, and that makes sense because they are an island nation dependant on imported energy resources. No one solution fits everybody.
FWIW, there is some rather silly opposition to ammonia and hydrogen on the basis of releasing nitrogen, nitrogen that makes up almost 70% of our atmosphere is apparently now a bad greenhouse gas!
The stupidity of that claim is even worse when you learn that the bulk of the nitrogen used in the production of the ammonia is drawn from the atmosphere. It's a circular process. The production of ammonia requires a green no carbon energy source like the sun, nuclear or geothermal to run. The big problem is that the public as a whole is rather stupid, and believe claims designed to oppose one green technology against the other.
Currently they use energy and resources to create ammonia that are not 100% carbon emissions free, which is why they only rate ammonia engines at up to about 90% carbon emissions free. Could it get to 100%, I don't think so because in real world scenarios there are no zero waste procedures.
