What is Biodiesel? • Scientifically: mono-alkyl esters of long chain fatty acids derived from vegetable oils or animal fats which conform to ASTM D6751 specifications for use in diesel engines. Biodiesel refers to the pure fuel before blending with diesel fuel. • A biofuel produced from any fat or oil through a refinery process called Transesterification http://www.biodiesel.org/resources/biodiesel_basics/

Typical Soybean Oil Methyl Ester Profile • The average molecular weight of soybean oil methyl esters is 292.2 g Source: http://www.biodiesel.org/pdf_files/fuelfactsheets/Weight&Formula.PDF
Biodiesel is… • Biodegradable • Nontoxic • Environmentally friendly (renewable) • Domestically Produced http://www.biodiesel.org/resources/biodiesel_basics/ http://www.afdc.energy.gov/afdc/fuels/biodiesel_benefits.html
Environmentally Friendly • Registered by Environmental Protection Agency (EPA) • Meets the standards of the 1990 Clean Air Act Amendments • Resources originate in United States • Less dependent on volatile politics of other countries supplying petroleum resources • Has a positive energy balance • Started at 3.2 in 1998, grew to 4.56 with better farming, planned for 5.44 by 2015. • http://www.biodiesel.org/pdf_files/fuelfactsheets/Benefits%20of%20Biodiesel.Pdf
Domestically Produced • Biodiesel has added $4.287 billion to the Gross Domestic Product (GDP). • Biodiesel has the potential to support more than 78,000 jobs by 2012. • Will reduce demand for imported oil from politically unstable regions. • http://www.biodiesel.org/pdf_files/fuelfactsheets/Benefits%20of%20Biodiesel.Pdf
Can be mixed with Petroleum based diesel fuel; mixtures named by % of biodiesel B-20 = 20% Biodiesel & B-100 = 100% Biodiesel • Can be used in existing diesel engines • Safer than other fuels (non-toxic, less explosive, less smell) • Operates in any kind of basic engine • Provides lubrication benefits • Reduction in harmful emissions ADVANTAGES http://energysources4thefuture.yolasite.com/biodiesel.php

How is the USA currently using biodiesel? • Largest biodiesel market: fleet vehicles (100) • Also, public transportation services – e.g. South Orange Village Shuttles 100% Biodiesel
Future Goals • Increase availability and use of biodiesel in all vehicles. Offer incentives to vehicle manufacturers to support higher blends (almost all current support B5). • Provide incentives for fleets to convert to Biodiesel and/or Biodiesel Blends. • Work with soybean industry to increase yield of soybean crops. http://biodiesel.org/
