On August 27, 2025, Höegh Autoliners announced an order for ammonia-burning Everllence B&W ME-LGIA engines, marking what the company described as a key step in its decarbonisation strategy.
The order covers four 7S60ME-LGIA dual-fuel engines to be delivered to an undisclosed Asian shipyard for installation in four 9,100 CEU Aurora-class Pure Car/Truck Carriers.
The engines will be built in South Korea by HD Hyundai Heavy Industries Co. Ltd.
Christian Ludwig, Head of Two-Stroke Sales and Promotion at Everllence, said: “We have now been running our two-stroke ammonia test engine since 2023 and can confirm that the ME-LGIA’s combustion is right where we want it. Using the Diesel principle, the ME-LGIA engine concept has many of the same merits as our existing dual-fuel engines that already entered operation over a decade ago. Inspired by these engines, we are – among other innovations – using the same sealing-oil design for the fuel-booster injection valves as this has proven to be particularly important and efficient. By end-2026, we tentatively expect to have a small number of demonstration projects on the water to enable a commercial market introduction of the G50-, S60-, G60-, G70- and G80-bore ME-LGIA engines based on positive service experience.”
The Aurora Class will be the largest Pure Car/Truck Carrier type built by Höegh Autoliners. The vessels were the first in the PCTC segment to receive ammonia-ready and methanol-ready notations from classification society DNV, and the new engines are designed by Everllence for potential zero-carbon ammonia propulsion.
