Biodiesel Fuel

With ever-rising fuel prices and an increasing dependence upon foreign oil, research into alternative fuel has become extremely important. Ethanol has quickly become a well-researched and known additive for conventional gasoline engines. For diesel engines, however, alternative fuels are just becoming more intensely researched. A potential replacement for petroleum diesel fuel that has come to the forefront in recent years is biodiesel. Biodiesel is a renewable fuel comprised of esters derived from vegetable oils. The vegetable oils can be from almost any oilbearing seed, such as soybean, corn or sunflower. The oil reacts with an alcohol such as methanol, but ethanol, another valuable product from crop production, can be used as well.

Long Meadow Ranch confirmed today that it had formally adopted a policy of exclusively employing biodiesel fuels in all of its farming equipment after more than two years of experimentation. Biodiesel is an alternative fuel produced from plant oils and animal fats that can supplant the use of conventional petroleum-based fuels in most diesel engines.

There are also several disadvantages to using biodiesel fuels. Overall, biodiesel has lower energy content than diesel fuel, causing a reduction in fuel economy. Current production costs keep biodiesel slightly more expensive than diesel fuel. The cold flow properties of biodiesel prevent it from being used in colder climates or in winter conditions. The flow characteristics of biodiesel have been shown to not work well in some diesel fuel injection systems. Though significant reductions in other emissions exist, biodiesel produces higher nitrous oxide emissions. The exact cause of this phenomenon is not exactly known. This greenhouse gas is becoming more strictly regulated by the government and more research needs to be completed to better understand how it is produced so it can be more effectively controlled.
