In a breakthrough for maritime decarbonisation, Höegh Autoliners has ordered four ammonia-burning Everllence B&W ME-LGIA dual-fuel engines, marking one of the first commercial applications of two-stroke ammonia propulsion.
The order covers 4 × 7S60ME-LGIA (Liquid Gas Injection Ammonia) engines, to be built by HD Hyundai Heavy Industries in South Korea, and will power four 9,100 CEU Aurora-class Pure Car/Truck Carriers (PCTCs) under construction at an undisclosed Asian shipyard.
Sebjørn Dahl, COO of Höegh Autoliners, said: “The engines are the beating heart of our vessels, and we take it as a clear mark of confidence that Everllence has chosen us to install some of the world’s first two-stroke ammonia engines. This collaboration underscores their trust in us as a reliable frontrunner in the shift to zero-emission shipping.”
For Everllence, the order represents a major step in bringing ammonia into commercial service. Bjarne Foldager, Head of Two-Stroke Business, noted: “We have adopted a safety-first approach to developing this engine given ammonia’s risk profile, and are confident it will become one of three key alternative fuels, alongside methanol and methane.”
Christian Ludwig, Head of Two-Stroke Sales and Promotion, added that Everllence’s test engine has been running successfully since 2023, with commercial introduction of ME-LGIA variants expected by 2026.
The Aurora Class will be the largest and most environmentally advanced PCTCs ever built. Awarded DNV’s ammonia-ready and methanol-ready notations, the vessels are designed to operate on zero-carbon fuels, further accelerating Höegh Autoliners’ decarbonisation strategy.
With delivery scheduled from 2027, Höegh’s Aurora Class is set to redefine sustainable deep-sea transportation.
