I never understood why shipping decided to deal with ammonia nonsense. It's dead-on-arrival, due to the complexity and danger of it. We already have a workable solution: liquid methane. It can be synthesized from captured CO2 about as cheaply as ammonia, and we can just use the fossil methane as a bridge for now. More importantly, there are whole fleets of methane-powered ships now. Methane has a higher global warming potential, but only if it leaks. And this can be minimized, especially once fossil fuel mining is phased out.
