Methanol gasoline, which is gasoline containing 15% methanol, is being produced around the world as an alternative fuel. While it provides benefits like being renewable and having a higher octane rating than gasoline, there are also challenges to address regarding its corrosiveness, production costs, and toxicity. Further testing is still needed to ensure the stability and safety of higher concentration methanol blends, especially regarding their effects on vehicle performance and emissions. IHI-E&C International Corporation is involved in methanol gasoline and other alternative fuel technologies.
