Ethanol is ethyl alcohol, which contains the same type of alcohol found in spirits, used as most commonly as motor fuel. Ethanol is available in a variety of blend levels. For instance, E10 is the most popular blend around the world – it contains 10% ethanol and 90% unleaded petrol. A flexible-fuel vehicle (FFV) would use higher ethanol concentration blends. The Australian government currently limits the amount of ethanol in petrol to 10%. There are currently three major facilities in Australia that produce fuel ethanol from grain, wheat/starch, and molasses, with total combined output only circling around 440 million litres per year.
