CNG 101
Keith GruetzmacherNovember 5, 2013
Terminology
• NGV – a vehicle that uses CNG or LNG fuel• CNG – natural gas @ 3600 psi, 70oF• LNG - natural gas @ 3.6 psi, -260oF• Bi-Fuel – uses natural gas or gasoline/diesel• Dual Fuel – uses both natural gas and
gasoline/diesel
• GGE: Gasoline Gallon Equivalent• The amount of natural gas containing the same
amount of energy as a gallon of gasoline. (125 ft3 or 1.25 Therms)
• 4 GGE = 5 Therms• DGE: Diesel Gallon Equivalent• The amount of natural gas containing the same
amount of energy as a gallon of Diesel (140 ft3 or 1.4 Therms)
• 5 DGE = 7 Therms
Terminology (continued)
Safety Benefits• Lighter than Air• Ignition Temperature = 1080° F• Flammability Range 5%-15% (gas to air mixture)• Non toxic• CNG is approved for all tunnels and bridges• Major Standard – NFPA 52 “Vehicular Gaseous
Fuel Systems Code”
Natural Gas Properties Safety Benefits
• Storage containers are designed, manufactured and tested to rigid specifications
• Bonfire test• Pressure test for 18,000 cycles of pressurization
and depressurization• Gunfire test• Crash test – cylinders dropped several feet• Cylinders include a pressure relief device

Compelling case forvehicle conversions
• Economic• Price stability and cost less• Incentives & funding• No pilferage• American Jobs Creation• Improved Balance of Trade
• Environment - Cleaner Air• Reduction in Greenhouse Gases -23%• Reduction is Diesel Particulate Matter- 27% • Improved Work Environment for Employees
• Energy Security Improved - North American fuel reducesAmerica’s dependence on Foreign Oil
Benefits
• Reduction in Noise – engines are quieter then diesel engines
• Increased Vehicle/Equipment Product Availability• Increased station equipment, station
installers/suppliers• Increases in Supply – Various US Shale Plays• Increased Industry Support
Benefits
Peoples Gas has seen tremendous growth
• NGV Therm Sales have increased by 544% and 182% in 2011 and 2012, respectively
• Number of customers has more than doubled in 2 years• 2010-5/207, 2011-8/300, 2012-12/412, 2013-21/601
• Have the potential to double the number of customers within the next year
• Have signed a new customer who at full build-out could potentially use more gas than the total of 2012
