A.P. Moller - Maersk has completed what it described as the first ship-to-ship commercial ethanol bunkering of a deep-sea container vessel in the United States, the company announced in a report carried by reports on 29 September 2026. The operation involved Tangier Maersk, a dual-fuel alcohol‑enabled container ship, and used corn ethanol produced in the United States as the bunkered fuel.
Maersk presented the operation as a milestone within its wider programme to investigate multiple fuel pathways for decarbonisation. The firm framed the trial as part of longer term work to understand the operational, technical and logistical dimensions of alternative marine fuels.
The announcement confirmed the fuel used was U.S.‑produced corn ethanol and that the receiving vessel was Tangier Maersk, which is equipped to run on alcohol fuels. No additional operational details, such as quantities bunkered or the precise location of the ship‑to‑ship transfer, were provided in the report.
The vessel and the fuel
Tangier Maersk was identified by Maersk as a dual‑fuel, alcohol‑enabled container vessel; the company said the ship consumed corn ethanol during the bunkering operation. That description places the ship among a growing number of deep‑sea vessels being built or modified to accept alternative liquid fuels rather than relying solely on conventional marine diesel or heavy fuel oil.
Corn ethanol was specified as the fuel source, reflecting a choice to test a commercially available, land‑based biofuel in a maritime setting. Maersk characterised the trial as a practical step in assessing whether such fuels can be integrated into routine operations at scale.
Implications for fuel pathways
Maersk framed the bunkering as one element of its exploration of multiple possible low‑emission fuel routes, signalling that ethanol is one of several options the company is evaluating. The company’s statement, as reported, did not commit to any single technology or timeline, instead presenting the trial as a data‑gathering exercise to inform future decisions.
By carrying out a commercial ship‑to‑ship transfer of corn ethanol for a deep‑sea container vessel, Maersk has added an operational case study to the discussion about how biofuels might be used in ocean shipping. The firm’s public position is that testing a range of fuels is necessary to compare fuels on availability, technical compatibility, supply chains and lifecycle emissions, though the announcement did not supply comparative data.
The Maersk report appeared in reports on 29 September 2026, and serves as the source for the company’s announcement of the completed ethanol bunkering. The report underscores Maersk’s stated intention to continue trials across different fuel types as part of its broader strategy to reduce greenhouse gas emissions from its fleet.
The wider shipping industry is watching such trials because the choice of alternative fuels will affect ship design, fuel logistics and ports infrastructure. For now, Maersk’s disclosed action is a discrete operational trial using a U.S.‑sourced biofuel and the company described it as the first commercial instance in the United States of ship‑to‑ship ethanol bunkering for a deep‑sea container vessel.
