What are Alcohol Fuels?
Ethanol and methanol are alcohol fuels. While both have been explored for motor vehicle use, it’s ethanol that’s really the alcohol fuel of choice today. Ethanol is a water-free, high-octane alcohol that is produced by sugar or starch fermentation. Ancient fermentation processes are still used to create ethanol from grain or renewable agricultural feedstocks. A yeast enzyme is introduced to change the sugar into ethanol. Ethanol is most commonly found blended in reformulated gasoline at 5% or 10% concentrations. Methanol is typically made by reforming natural gas, a fossil fuel.
