A new industry study has concluded that ethanol produced in the United States could be used to fuel vessels that are already configured to burn methanol, with only limited changes required to dual-fuel engines and to bunkering operations, MarineLink Maritime News reported on 12 November 2026.
The research argues ethanol may provide a practical alternative for the expanding fleet of methanol-capable ships while supplies of low-emission methanol remain constrained. The summary of the study highlights compatibility with existing ship systems as central to the finding.
Operational implications
According to the study, existing dual-fuel engines designed for methanol can accept ethanol with only modest modifications. The report also notes that adjustments to bunkering infrastructure would be limited, implying that ship operators and fuel suppliers might avoid major new investments to deploy ethanol bunkers.
Market context
The study positions ethanol as a stopgap option while low-emission methanol availability is tight. It does not, in the summary provided, set out timescales or quantify the volumes of ethanol that would be required to replace constrained methanol supplies.
Authors of the study describe a growing population of methanol-capable ships, and they suggest that using ethanol could expand immediate fuel options for that fleet. The paper frames ethanol as an alternative pathway rather than a full replacement for methanol in decarbonisation strategies.
The analysis is careful to limit its claims to technical compatibility and short-term supply relief. It stops short of addressing regulatory, lifecycle-carbon or economic comparisons in the summary, leaving those areas for further scrutiny.
Wider industry reaction and the next steps for testing, certification and regulatory approval were not detailed in the summary. Stakeholders will require full study access and subsequent trials before any significant shift in bunkering practice can be expected.
In the short term the study offers shipping operators an additional option to consider for vessels already prepared for methanol use, while the longer-term role of ethanol in maritime decarbonisation will depend on further technical work and market developments.
