Ammonia propulsion is moving from concept to commercial reality as several engine developers bring dual‑fuel designs to market. Everllence’s new ME‑LGIA engine integrates advanced safety barriers, digital connectivity, and fuel flexibility, marking a significant step towards practical zero‑carbon deep‑sea shipping.
As the maritime industry accelerates towards decarbonization, the transition to low greenhouse gas fuels is essential. Liquefied natural gas and methanol have led the way, but ammonia is making some strides. With three ammonia-capable ships already in operation and another 45 on order, momentum is building.
Driving decarbonization with ammonia
Ammonia offers compelling advantages. It is carbon-free at the point of combustion and can significantly reduce overall emissions when produced from renewable sources. Its volumetric energy density makes it suitable for deep-sea shipping, where long voyages demand robust fuel solutions.
However, adoption is not without hurdles. Ammonia’s high toxicity and corrosive nature require stringent safety measures and specialized handling protocols, far beyond those for conventional fuels. Questions around bunkering infrastructure, crew training, and life-cycle emissions remain critical. Nonetheless, ammonia represents a viable option for the future of shipping if these challenges can be solved.
Engine developers commit to ammonia
As momentum gathers, engine manufacturers are stepping up to develop propulsion systems suited for ammonia.
WinGD and J-ENG delivered their first dual-fuel two-stroke engines in late 2025, followed by Everllence in early 2026, while Hyundai’s HiMSEN H22CDF-LA four-stroke engine has already achieved multiclass approval.
Among the vessels on order, seven, including those from shipowners such as Höegh Autoliners and Eastern Pacific Shipping, will feature Everllence’s newly…
