  1. CNGIs It Right For You ? Energy Vision Workshop September 2010 David Lynch

  2. What is Changing ? • Speed of Change • Concern for the Environment

  3. Where Have We Been?

  4. Alternative Fuel Properties CharacteristicsDiesel Biodiesel MeOHEtOHNGLPG Structure C18H36 C1 8H35O2 CH3OH C2H5OH CH4 C3H8 Cetane No. 40+ 40+ 10 10 -- 5 Octane No. -- -- 95 95 120 95 Energy (LHV) btu/gal(x1000) 128 119 57 76 85(LNG) 84 btu/cu. ft 1000(CNG) Energy Storage 1 1.1 2.3 1.7 1.7 (LNG) 1.6 (relative vol.) 3.7 (CNG)

  5. Where Have We Been? • Spark Ignited Gasoline • Add the lead • Get the lead out -- 100 Octane to 87/91/93 • Electronically Controlled Engines • Add EGR • Add the catalytic converter • Fuel Injection • Direct fuel injection • Turbocharging • ????????

  6. Where Have We Been? • Diesel • High Speed Diesel • Turbocharging • Aftercooling • Electronic Controls • EGR • Particulate Traps • SCR (Diesel Fluid) • Tomorrow – Electronically Boosted Turbocharging • ??????

  7. Where Have We Been? • Natural Gas Engines • 120 Equivalent Octane Rating • Turbocharging • Aftercooling • Electronic Controls • EGR • Stoichiometric Mixture • Three Way Catalyst • Biomethane Compatible

  8. What is changing? • Higher vehicle pricing for new technology • Higher cost of Ultra Low Sulfur diesel fuel • SCR for 2010 • Total Cost of Operation

  9. What are your alternatives? • Get out your checkbook • Conserve diesel fuel however you can • Change vehicle specifications • Truck specs for fuel economy • Consider other alternatives

  10. Consider the Natural Gas Alternative • Things have changed • Natural gas not for everyone BUT makes sense for an expanding customer base • Natural gas as the lower cost alternative

  11. Large, Domestically Available Supply Supplied FromUS and Canada Imported 98% Natural Gas • Less than .01% used for transportation in U.S. • 10 million NGVs would use about 3% • World NG reserves estimated at 3x that of oil • Huge advances being made in bio-methane • landfill gas (LFG), dairy farms, wastewater treatment plants • NGVs offer solution to dependence on foreign oil • U.S. imports up to 70% of its oil at a cost of $ 350 billion a year Source – Clean Energy 2009

  12. 2010 Natural Gas Truck and Bus Engine • 8.9 litre Stoichiometric Cooled EGR engine • Ratings from 250 to 320 hp • ISL G replaced L Gas Plus and C Gas Plus engines in 2007 • Low emissions • First heavy duty engine for bus and truck certified to 2010 EPA and CARB NOx standards • 0.20 g/bhp-hr NOx • 0.01 g/bhp-hr PM • Three Way Catalyst Aftertreatment • Diesel like Performance, Reliability, Durability • Over 30% more torque at idle vs. previous engine • Improved fuel economy- +5% vs. C Gas Plus • Manufactured in Cummins Engine Plant- Rocky Mount, North Carolina

  13. Natural Gas Applications TRUCK BUS REFUSE SPECIALTY

  14. Conclusions • The economics of vehicle operations are shifting • Several sources of funding makes Natural Gas a Bargain. • Some businesses will profit from the opportunity.

  15. Change is Inevitable “except from a vending machine”
