ISO issues standards for methanol as a marine fuel
New Global Standards for Methanol as Marine Fuel to Promote Cleaner Shipping
The International Organization for Standardization (ISO) has released guidelines for using methanol as a marine fuel. This new document is meant to create clear rules for using methanol on ships worldwide. It was put together with the help of ship owners, operators, classification societies, national standards bodies, and other technical experts. The goal is to make sure everyone follows the same standards when using methanol as a fuel.
Three Types of Marine Methanol
The new guidelines introduce three types of methanol for marine use:
- Marine Methanol Grade A (MMA)
- Marine Methanol Grade B (MMB)
- Marine Methanol Grade C (MMC)
These categories cover methanol made from all kinds of production methods. They can be used in different types of marine engines, such as diesel engines and fuel cells, as well as other marine equipment. The standards also apply to land-based uses that are similar to marine applications.
Focus on Quality and Safety
The document provides detailed information on what type of methanol is suitable for marine environments. It describes things like purity, appearance, impurities, and important chemical properties. The guidelines also mention existing industry standards from groups like the International Methanol Producers and Consumers Association (IMPCA) and ASTM. These groups have rules about testing and measuring fuel quality.
One key concern in the document is safety. Methanol has a low flash point—around 11°C—which means it can catch fire easily if not handled properly. The guidelines stress the importance of following safety rules and setting up the right safety measures before using methanol. Even though the document does not cover all safety and health issues, it points readers to safety data sheets and other resources to find more information.
Why This Matters
These new standards are expected to be important for the future of the shipping industry. More and more, the world is looking for cleaner and more sustainable fuel options. Methanol is seen as a better choice for the environment compared to traditional fuels. By having a global standard, the ISO hopes to support the shift to greener energy in shipping, helping to reduce pollution and support cleaner oceans.
