"Combusting ammonia, NH3, does not produce any carbon dioxide and produces 8,120 Btu/lb. The fact that ammonia does not produce any carbon dioxide has been recognized by both engine manufactures and environmentally conscious ship owners. Recently some engine manufacturers have announced they will have ammonia fuel engines developed by 2024 and available for ships by 2025. The Italian shipowner, the Grimaldi Group, recently signed an order for the construction of up to ten ammonia ready pure car and truck carriers."
"Additionally, burning ammonia in engines does not necessarily increase NOx emissions despite the fuel-bound nitrogen. Lower levels of NOx emissions were observed if energy substitution by ammonia did not exceed 60%. This is thought to occur because of the lower combustion temperature of ammonia."
"Shipowners starting to commit to building ammonia ready ships is a good sign, however, with new construction accounting for only two percent of the world's fleet replacement per year it will take decades for the marine industry to wean away from hydrocarbon fuels."
We know that MSAR and bioMSAR combust at lower temperatures. So Green Ammonia could potentially blend in with Biofuel and Glycerine etc to make another zero/low CO2 low NOx variant to bioMSAR. No need for new Ammonia ready ships and thus no decades to transition to low carbon fuel.
As you'd expect, I have sent the suggestion to QFI just in case they haven't yet considered the option.
