Natural Gas Fuel Proper/es !  Rela/vely low energy density compared with conven/onal transporta/on fuels !  Therefore must be compressed (CNG) or liquefied (LNG) in order to have sufficient energy for vehicle use !  Energy Density: o  Petro-­‐Diesel o  Bio-­‐Diesel o  Ethanol 36 MJ/L 33 MJ/L 23 MJ/L o  LNG (20 psig)
21 MJ/L o  CNG (3000 psig) 7.5 MJ/L CNG and LNG CNG – Compressed Natural Gas !  Natural gas stored on the vehicle at high pressure in special reinforced containers o  Public sta/ons – historically dispensed at 3,000 psi (regula/ons changing to allow 3,600 psi dispensing) o  Private sta/ons – op/on to dispense at up to 3,600 psi LNG – Liquefied Natural Gas !  Natural gas cooled to -­‐162 °C, becomes liquid !  Must be kept at this low temperature to remain liquid !  NGVs that use LNG incorporate systems to vaporize the liquid to a gaseous state for use in the engine o  Therefore suited to vehicles with high daily mileage o  LNG has greater energy density than CNG = improved range o  Liquid form requires less weight and space for equivalent fuel storage than CNG Natural Gas Safety Natural gas is: !  Lighter than air (unlike propane) !  Non-­‐toxic !  Inherently safer than liquid fuels such as gasoline or diesel: o  Due to narrow flammability range and higher igni/on temperature o  Will not pool or seep into the ground o  Both CNG and LNG dissipate quickly in the event of an accident or leak o  Will not corrode other materials or contaminate soil or groundwater o  Odourized by local distribu/on company for ease of detec/on (CNG only) ATCO Gas Support !  Opportunity evaluaDon: o  Provide informa/on and resources o  Assist with determining appropriate solu/on fit (CNG or LNG) o  High-­‐level economic analysis for CNG applica/ons !  Support detailed economic analysis and project implementa/on !  Public access sta/ons can be u/lized for pilot project assessment !  Distribu/on system /e-­‐in for CNG sta/ons CNG / LNG Fit Decision Decision Considerations

CNG Refuelling Fast fill staDon •  Fill /mes comparable to gasoline or diesel •  Sta/on cost increases as fill /me decreases •  Heat of compression may impact fuel storage and therefore range Time fill staDon !  Ideal for fleets that can refuel overnight !  Decreased sta/on infrastructure cost vs. fast fill Images courtesy Cummins Westport Inc.
