If we are thinking about ammonia as a fuel, why not go with hydrazine? It’s not as immediately lethal as ammonia and is much easier to contain and manipulate.

Hydrazine may not be as immediately lethal by inhalation but it's considered a probable human carcinogen by the EPA. It has more explosion/fire risk. It's also more expensive to synthesize starting from clean primary energy (nuclear or renewables).
