The high-pressure injection concept deployed in X-DF-A engines will be familiar to operators of the WinGD well-established, highly efficient diesel-fuelled X-Engines. Notable features include comparable performance with X-Engines in both ammonia mode and diesel mode, low pilot fuel requirements precisely controlled through common rail injection and NOx Tier III compliance in both modes with Selective Catalytic Reduction (SCR). 

Already traded globally as a fertiliser feedstock, refrigerant and industrial chemical, ammonia is set to become a mainstream energy carrier and fuel in the coming decades. Greenhouse gas emissions associated with its production and distribution can be nearly eliminated with the use of renewable electricity, making green ammonia a viable option for meeting societal and corporate climate goals – at the same time minimising owner and charterer exposure to forthcoming carbon pricing.
