Biodiesel: A Healthy And Flexible Alternative to Petroleum Diesel Biodiesel: A General Definition Biodiesel is not raw vegetable oil. It is produced by a chemical process that removes glycerin from the oil. Biodiesel is a domestic, renewable fuel for diesel engines derived from natural oils such as soybean oil or recycled cooking oil that meets the specifications of ASTM D 6751. Biodiesel is registered with the U.S. EPA as a legal fuel and has completed rigorous Tier I and Tier II Health Effects Testing. Biodiesel can be used in any concentration with petroleumbased diesel fuel in existing diesel engines with little or no modification. Biodiesel Production 100 lbs. of soybean oil + 10 lbs. methanol = 100 lbs. soy biodiesel (B100) + 10 lbs. of glycerin Describing Biodiesel Blends • B100 = 100% Biodiesel • B20 = 80% Petroleum Diesel / 20% Biodiesel – 1500 gallons B100 + 6000 gallons petroleum = B20 Transport Load • B5 – 95% Petroleum Diesel / 5% Biodiesel Biodiesel is a simple and effective alternative to Petroleum Diesel Reduces harmful emissions Runs in diesel engines with no modifications. Uses existing fueling infrastructure. Meets Federal Standards Reduces petroleum dependence. How Does Biodiesel Perform Compared to Petroleum Diesel Fuel? • High Cetane (>50 vs. 42) • Comparable BTU content (120,000 BTU/gal vs. 126,000) • High lubricity (> 6000g vs 3100g SLBOCLE) • Readily mixes with diesel • Flashpoint exceeds 300 F OEM Warranty OEM Warranty (cont.)

Public Reaction What to do with what we have? Diesel Power is THE prime mover for school buses.

Creates a tax credit for biodiesel • • All taxable gallons allow the credit to be claimed in both taxable and tax-exempt markets • • • $1 per gallon tax credit for each gallon of pure biodiesel made from virgin oils derived from agricultural products and animal fats $.50 per gallon tax credit for each gallon of pure biodiesel made from other oils Tax-exempt fleet fuel programs Off-road diesel markets (dyed diesel) Heating oil, Boiler Fuel, Power Generation Streamlines the use of biodiesel at the terminal rack • The tax structure and credit will encourage petroleum blenders to blend biodiesel as far upstream as possible, which under the RFS or Minnesota’s 2% volume requirement will allow more biodiesel to be used in the marketplace Who is using biodiesel?
