Hyundai Heavy Industries’ Engine Machinery, (HD HHI-EMD) is scheduled to deliver a large ammonia dual-fuel engine in the first half of 2025, to be installed in what is believed to be the world’s inaugural ammonia-powered vessel, constructed by Hyundai Mipo Dockyard.

The engine is a 6X52DF-A, developed in collaboration with Switzerland’s WinGD. Extensive discussions and cooperation have taken place to ensure the engine’s optimal performance and safety. This collaborative effort involved shipowners, shipyards, and vessel operators, all with the objective of minimising GHG emissions. To achieve this goal, the engine incorporates combustion optimisation technology and exhaust gas post-processing technology, addressing challenges such as NOx emission regulations and ammonia slip.

HD HHI-EMD says that this marks the initial phase of the ammonia fuel engine market, which is gaining significant attention as an eco-friendly, carbon-free fuel for the future. HD HHI-EMD anticipates a gradual expansion of this market to encompass other vessel categories, including tankers and bulk carriers.

HD HHI-EMD has set its sights on developing its proprietary four-stroke HiMSEN Engine’s ammonia dual-fuel engine, in order to assume a leading role in the maritime industry’s journey towards carbon neutrality and offer a diverse range of solutions to its customers.
