AP Moller – Maersk (Maersk) on Monday (28 September) announced the successful bunkering of Tangier Maersk , a dual-fuel alcohol-enabled container vessel, using US-produced corn ethanol. The company said the operation marked the first ship-to-ship commercial ethanol bunkering of a deep-sea container vessel in the United States. “The milestone is part of Maersk’s broader efforts to explore multiple potential fuel pathways for the future of shipping,” Maersk said in a statement. This operation provided valuable insight into the operational, infrastructure, sourcing and supply chain considerations for using ethanol as a marine fuel. While ethanol benefits from an established production base, existing infrastructure and compatibility with alcohol-enabled vessel technology, scalable future fuel pathways will also depend on fuel availability, regulation and operational readiness across the maritime value chain. Ditlev Blicher, Maersk Regional President for North America , said: “Achieving lower-emission logistics requires turning new technologies into practical, scalable solutions. This bunkering operation aboard Tangier Maersk provides valuable real-world experience with alternative fuels in commercial shipping.” “The insights gained will help drive the development of more sustainable supply chains.” The operation builds on previous ethanol trials aboard Laura Maersk and Antonia Maersk and reflects Maersk’s continued commitment to exploring and advancing credible pathways to drive progress within the shipping industry’s energy transition.   Photo credit: AP Moller – Maersk Published: 30 September, 2026
