Knowra Ethanol fuel Ethanol fuel Ethanol fuel is ethyl alcohol used as an energy source, either alone or blended with gasoline. It is commonly produced by fermenting plant-derived sugars or starches.
Alcoholic fermentation : A metabolic process in which microorganisms convert sugars into ethanol and carbon dioxide. Yeast fermentation produces much of the ethanol used in fuel.
Flex-fuel vehicle : A vehicle designed to operate on gasoline or blends containing high proportions of ethanol. Flex-fuel vehicles can use E85 where compatible fuel is available.
Life-cycle greenhouse gas emissions : Greenhouse gas emissions summed across a product's production, distribution, use, and disposal. Ethanol's climate benefit depends on feedstock, processing energy, and land-use change.
Gasoline : A volatile petroleum-derived mixture used mainly as fuel in spark-ignition engines. Gasoline is ethanol's principal blending partner and the baseline for energy-density comparisons.
Henry Ford : An American industrialist who founded the Ford Motor Company and shaped mass automobile production. Ford designed the Model T to run on gasoline, ethanol, or blends of both.
Distillation : A separation process that uses differences in volatility to enrich one component of a liquid mixture. Fuel ethanol is distilled from fermented mixtures before further dehydration.
E10 : A fuel blend containing up to 10 percent ethanol and at least 90 percent gasoline by volume. E10 is a common low-level ethanol blend for conventional gasoline vehicles.
Indirect land-use change : Changes in land use caused indirectly when demand for a commodity displaces existing production elsewhere. Biofuel demand can shift farming and land conversion beyond the fields growing fuel crops.
Methanol fuel : Fuel made from methanol, a one-carbon alcohol used in engines and fuel blends. Methanol is a related alcohol fuel with different toxicity, production routes, and engine properties.
Model T : The Ford automobile produced from 1908 to 1927 that helped popularize mass car ownership. Its early capability to use ethanol reflects fuel choices before gasoline became dominant.
