ISO introduces standards for methanol as marine fuel

In Greece, Safety4Sea reports the International Organization for Standardization released a comprehensive framework to standardize the use of methanol as a marine fuel, addressing safety, quality, and sustainability in response to the maritime industry’s push for low-emission alternatives. Developed with input from ship owners, operators, classification societies, and technical bodies, the document defines methanol grades A, B, and C, covering all production methods and uses, including marine engines and fuel cells.

The new specifications address chemical properties such as purity and allowable impurities while drawing on existing benchmarks from organizations like the International Methanol Producers and Consumers Association and ASTM. These standards also extend to land-based systems mirroring maritime applications.

While methanol offers significant sustainability benefits, its low flash point of 11°C highlights safety risks. ISO emphasizes the importance of strict safety measures, advising users to develop handling protocols and adhere to regulatory limits. Additional resources, such as safety data sheets, are recommended for detailed precautions.
