Throughout 2024, the maritime industry witnessed groundbreaking advancements in alternative fuel solutions and technologies aimed at decarbonization. The year started with MAN ES and Mitsui E&S achieving a world-first by successfully conducting a hydrogen combustion test on a large marine 2-stroke engine, showcasing significant greenhouse gas emission reductions of up to 95%. Following this milestone, ABS published an advisory on methanol bunkering, addressing crucial technical and operational challenges. In June, X-Press Feeders celebrated the retrofit of the first methanol dual-fuel boxship and launched Europe's maiden green methanol-powered feeder network. Further showcasing the industry's commitment to decarbonization, NYK introduced the world's first ammonia-fueled ship for commercial use, while the GCMD-led consortium performed a groundbreaking ship-to-ship transfer of ammonia at anchorages, signaling progress in utilizing alternative fuels. Additionally, Amogy's ammonia-powered vessel and HD Hyundai's zero-carbon ammonia dual-fuel engine demonstrated the industry's dedication to innovative solutions. Maersk made headlines in November with the conversion of Maersk Halifax into a methanol dual-fuel vessel, further solidifying the industry's shift towards cleaner fuels. The year concluded with MAN ES initiating full-scale ammonia engine testing, highlighting a new phase in the development of ammonia-powered engines. Similarly, WinGD's successful full-load test of the X-DF-M methanol-fueled engine showcased the feasibility and progress of methanol as a viable maritime fuel. These milestones collectively depict a positive outlook on the industry's efforts towards sustainable and decarbonized maritime operations.
