  1. West Chester University of Pennsylvania Founded 1871 Pennsylvania State System of Higher Education (PASSHE) Fourteen Universities owned and operated by the Commonwealth of Pennsylvania Approx. 15,100 degree seeking students: 2,266 graduate and 12,834 undergraduate (Fall 2011) More than 800 full and part time faculty More than 600 full and part time support staff 403 acres located 25 miles west of Philadelphia

  2. J. Royston Gathings 821 S. Matlack St., West Chester, PA 19382 West Chester University has been a leader in the region for more than a decade in using Compressed Natural Gas (CNG) fueled vehicles as an environmentally friendly alternative to traditional gasoline cars and light trucks.

  3. 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.

  4. Station was moved from center of campus to present location on March 13th, 2008.

  5. ANGI International Fast Fill StationANGI Int’l of Janesville, WI Ingersoll-Rand Model 20H40NG Air Cooled 4 Stage Reciprocating Compressor 30 hp Electric Motor Inlet Pressure 16 psi /Discharge Pressure 4,100 psi Approx. 40 SCFM ANGI Built Dispenser w/ MicroMotion Mass Flow and Density Sensor Storage built in McKeesport, PA

  6. FuelMaker Time Fill Unit Available in 3000 and 3600 psi configuration Available with one and two fill hoses WCU staff modified unit to include an hour meter for monitoring use – approx. .9 gge/hour

  7. WCU has 22 vehicles capable of running on CNG, reflecting 26% of its total fleet of 82 vehicles.

  8. Full Size GM Bi-Fuel CNG Pickup 6.0 Liter V8 BiFuel Gas/CNG Available both 2 and 4 wd With both Gasoline and CNG tanks full, this truck traveled 180 miles on CNG and more than 630 miles.

  12. Did You Know……. CNG storage cylinders, manufactured to Federal Motor Vehicle Safety Standard (FMVSS) 304 and American National Standard Institute (ANSI) NGV 2 have a useful life of 15, 20 or 25 years from the date of manufacture, depending upon the manufacturer’s specifications. Once the cylinder reaches the end of its useful life as stated on the cylinder label, or if a cylinder is damaged, it must be defueled and disposed of in accordance with the cylinder manufacturers’ guidelines or CGA guidance documents. Compressed Gas Association

  13. Did you know…..? • CNG is 92% Methane, but also contains Ethane, Propane, Butanes, Pentanes, Hexanes, CO2 and Nitrogen? • That natural gas is lighter than air? • The flammability range of natural gas is relatively narrow? • The auto-ignition temperature of natural gas is nearly twice that of gasoline? • CNG has a published octane rating of 120 or 130, depending on who you believe. • Generally considered non-carcinogenic • The cost per BTU of CNG is currently less than any other alt fuel? • The largest source of hydrogen is methane gas?Natural gas reforming is the most common method of creating hydrogen.

  14. How Clean is CNG? The U.S. Environmental Protection Agency (EPA) estimates that light duty natural gas vehicles emit 60 to 90 percent fewer smog-producing pollutants and 30 to 40 percent fewer greenhouse-gas emissions. In some big cities, according to NaturalGas.org, emissions can actually be cleaner than the surrounding air. An average dedicated natural-gas vehicle emits about 70 percent less carbon monoxide and 87 percent less NOx (nitrogen oxides) than a similar gasoline-engine vehicle.

  15. WCU Fuel ConsumptionWCU’s use of Gasoline and Diesel fuels has been offset by the increased use of cleaner burning CNG and BioDiesel B20 ! • 20012008 Difference • Gasoline 37289 29381 -7908 • Diesel/B20 5462 5032 -430 • CNG 1737 10321 +8584 • Total Pumped 44489 44734 +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.

  16. Initial investment in infrastructure was costly, but long term savings for the University are being realized.

  17. Historically, natural gas has consistently been 20 to 45 percent less costly than its gasoline gallon equivalent (gge). As an example, when gasoline was peaking at over $4.00/gallon during summer 2008, PECO Energy’s published rate on July 31st, 2008 for selling CNG retail at its facility in Coatesville, PA was $2.30/gge, a savings of more than $1.70/gallon. Natural Gas is at a 10 year low!!!

  22. Challenges of CNG • Acceptance – Using CNG isn’t harder, it’s just different. • Costs of Ownership • Infrastructure – vehicle and refueling • Parts Availability - Longevity • Training and technical resources for technicians and station operators.

  23. Challenges of CNG • Learning curve for manufacturers • Marketing • Regulatory – Testing and inspection of cylinders, relief valves, compressor equipment, conversion installations. • Liability
