West Chester University’s Alternative Fuel Vehicle Program Compressed Natural Gas BioDiesel B20 University Garage West Chester University West Chester, PA.
Alternative Fuels Overview On April 24, 1998 WCU celebrated the grand opening of its compressed natural gas refueling center, becoming the first Pennsylvania college or university east of Pittsburgh to start a CNG vehicle program, and bringing WCU in compliance with the Clean Air Act Amendments of 1990 and the National Energy Policy Act of 1992. §WCU replaced traditional Diesel fuel with BioDiesel B20 in April, 2008. §West Chester University has 22 CNG capable vehicles with more on the way! §WCU has 6 trucks and 12 pieces of grounds equipment operating on BioDiesel B20.
Alternative Fuels Facts l Compressed Natural Gas (CNG) l Ethanol (E85) l Liquefied Natural Gas (LNG) l Propane - Liquefied Propane Gas (LPG) l BioDiesel l Electric (EV) and Hybrid Electric (HEV) Commonly Used Alternative Fuels for Transportation include:
Why use Alternative Fuels? For cleaner air For less dependence on foreign oil For lower cost fuel What is Compressed Natural Gas (CNG)? CNG is 92% Methane, but also contains Ethane, Propane, Butanes, Pentanes, Hexanes, CO2 and Nitrogen.
Where Does WCU Get its CNG? It’s the same gas piped right from the street mains used to supply our homes for heat, hot water heaters, and stoves. WCU has a “Fast Fill” pumping facility that compresses the natural gas from a street pressure of about 20 psi to approximately 4000 psi. Refuels vehicles in a matter of minutes. WCU has a “Slow Fill” unit that can refuel vehicles overnight.
What Else Should I Know? l Every kind of vehicle is available with some type Alternative Fuel Engine l Some alternative fuels are available only in some regions l There are special grants and tax incentives available to promote the use of Alternative Fuel Vehicles
How much does CNG cost? §CNG costs about 30% less per Gasoline Gallon Equivalent (GGE) than gasoline. §Costs associated with dispensing equipment and additional vehicle costs associated with CNG are funded in part by grants available from governmental agencies.
WCU Fuel Consumption WCU’s use of Gasoline and Diesel fuels has been offset by the increased use of cleaner burning CNG and BioDiesel B20 ! § 20012008 Difference §Gasoline3728929381-7908 §Diesel/B2054625032-430 §CNG173710321+8584 §Total Pumped4448944734+245 WCU used more than 10,000 Gasoline Gallon Equivalency of CNG in FY 2008. From 2001 to 2006, WCU increased the number of vehicles using diesel type fuel, and decreased the amount of diesel type fuel being used.
How Clean is CNG? CNG vehicles demonstrate an 80% reduction in ozone forming emissions. CNG vehicles emit*: 90 – 97% less Carbon Monoxide (CO) 50 – 75% less Hydrocarbons (HC) 35 – 60% fewer Oxides of Nitrogen (NOx) 90 – 97% less Particulate Matter 97 – 99% less Benzene 25 % less Carbon Dioxide 100% reduction of Lead and Sulfur emissions *Compared with Reformulated Gasoline. *Percentages vary with type of vehicle.
What is BioDiesel? BioDiesel (Methyl Esters) can be made from many different feed stocks: Soybean and Rapeseed are most common Restaurant waste oils (waste trap oil) Animal fats can also be used Manufactured as “B100”, but generally marketed as “B20”, which is 80% traditional diesel mixed with 20% BioDiesel ASTM D6751 standard approved to insure quality
Higher Cetane Rating Higher Lubricity No Sulfur Lower Particulate Emissions Less Exhaust Smell Renewable Resource No Modifications to Post-1980 era Engines – Just Pour and Go! BioDiesel Benefits are: What Else Should I Know? BioDiesel has a shorter shelf life than traditional diesel Higher “cloud point” – less forgiving in temps below 32 deg. Fahrenheit Concerns about farm cropland being used for Fuel production instead of Food production Farmland not being “rested” between crops.
