Many car dealers in Utah now carry inventories of vehicles that run on biodiesel. Several car models, such as Audi, BMW, Chevrolet, Daimler Chrysler, Ford, and General Motors, can run on biodiesel. Biodiesel is a clean-burning, domestically produced, renewable substitute for petroleum diesel. The use of biodiesel as fuel will improve vehicle energy, security, and air quality and contribute to environmental cleanliness.

Biodiesel is produced by converting organic fats and oils into fatty acid methyl esters (FAME) through a chemical process called transesterification. Biodiesel can be produced from vegetable oil, animal fats, and waste cooking oil. The main oils used in the production of biodiesel include soybean, palm, and rapeseed.

The transesterification process involves the exchange of the alkoxy group of an ester compound by another alcohol, producing a reaction that is catalyzed when an acid or base is added. The transesterification process features the separation of the ester and glycerol layers after the reaction time. The heavier glycerol settles out and may be used in other industries, including cosmetics and pharmaceuticals.

Biodiesel fuel has a number of advantages over fossil fuels. Consider the following:

  • Biodiesel produces fewer greenhouse gasses than fossil fuels. The carbon dioxide produced in the burning of biodiesel fuel is offset by the carbon dioxide absorption of the plants that produce the oil used in the production of biodiesel.
  • Biodiesel provides greater fuel security for those countries with little or no oil reserves. Countries that are bereft of oil need to import their oil, a move that may result in trade imbalance or deficit. A country dependent on oil imports is subject to supply disruption and unstable pricing. When a country is able to produce its own biodiesel, it will be less vulnerable to the whims and price fluctuations of the oil-producing nations.
  • Biodiesel does not produce particulates. This improves fuel lubricity and the cetane number of the fuel that will result in shorter ignition delay periods. Improved lubricity protects the engine’s moving parts from premature wear.
