An alternative fuel; a colorless, nearly odorless, volatile alcohol used in transportation as a vehicle fuel by itself or blended with gasoline (M85 – a blend of 85% methanol and 15% gasoline); a liquid alcohol fuel with vapor heavier than air; primarily produced from natural gas. It is not commonly used because automakers are no longer supplying methanol-powered vehicles. In the future, methanol could possibly be the fuel of choice for providing the hydrogen necessary to power fuel cell vehicles.
