Saddle Creek Transportation: A Case for Natural Gas as a Transportation Fuel

Saddle Creek Transportation has enjoyed the benefits of natural gas as a transportation fuel for over two -and- a -half years, and are continuing to increase their number of natural gas powered trucks. Watch our latest video to find out why they are so excited about their natural gas program.

Cost Effective

  • Less volatile fuel prices, creates long-term cost benefits over diesel
  • State and Local Government programs may provide incentives in your area to offset costs

Cleaner

  • Eliminates need for all diesel exhaust treatment systems
  • 20%-25% GHG reduction
  • Almost no particulates
  • Substantial reduction in VOCs, SO2 and NOx- No smell or smoke and quieter than diesel

Proven

  • Proven, safe and reliable technology
  • Vehicles, equipment and fuel all readily available
  • Thousands of vehicles already on the road logging miles and savings

Compressed CNG

  • Physical Form: Gas stored at high pressure at 3,600 psi
  • Volume vs Diesel: 4x
  • Cost: Lower cost to produce and store
  • Refueling: Easy
  • System Pressure: 60 - 4,500 psi
  • Hold Time: Unlimited (no fuel loss)
  • Storage: Carbon fiber wrapped cylinders
  • Conclusions: New, lightweight large capacity CNG tanks enable long-haul trucking applications.

Liquefied LNG

  • Physical Form: Liquid produced cryogenically at -260F
  • Volume vs Diesel: 2x
  • Cost: Higher cost to process, liquefy and store
  • Refueling: Requires special handling equipment
  • System Pressure: 60 - 230 psi
  • Hold Time: Limited (fuel will vent if not used)
  • Storage: Vacuum-insulated stainless steel tanks
  • Conclusions: LNG's high energy density makes it relevant to trucking and off-road applications where space is at a premium.

CNG Conversion Formulas

Pounds of CNG Fuel Lbs. of CNG @ 3,600 PSI = Water Volume (cu. in.) multiplied by 0.0079
Lbs. of CNG @ 3,000 PSI = Water Volume (cu. in.) multiplied by 0.0069
Standard Cubic Feet (SCF) SCF @ 70°F and 3,600 PSI = Water Volume (cu. in.) divided by 5.861
SCF @ 70°F and 3,000 PSI = Water Volume (cu. in.) divided by 6.657
Diesel/Gasoline Gallon Equivalents Gasoline Gallon Equivalent (GGE) = SCF of Natural Gas divided by 123
Diesel Gallon Equivalent (DGE) = SCF of Natural Gas divided by 139
