NGV Infrastructure Introduction

  1. 1. Natural Gas Fueling (CNG & LNG)Infrastructure Design, Development & Fleet Deployment S
  2. 2. What is Natural Gas?S Natural Gas is primarily methane gas which can be drilled for exclusively or produced as a by product of oil explorationS Natural gas used in transportation fuel has been treated to eliminate Carbon Dioxide (CO2), Hydrogen Sulfide (H2S) and moisture (H2O) as well as any other impurities found in the raw feedstock. This ensures the fuel delivery system in the vehicle operates properly and does not fail due to contaminationS Liquefied Natural Gas (LNG) is methane gas that has been chilled to -260 degrees F and stored at pressures under 100 psigS Compressed Natural Gas (CNG) is pipeline quality gas that has been compressed and stored at pressures of 3600 psig or greater
  3. 3. Why Natural Gas?S Domestic gas supplies are substantial and secure which decrease our dependence on foreign oil and stabilizes natural gas priceS Current spread between oil futures and natural gas futures, along with long term supply estimates, indicate long term price stabilityS Natural Gas Vehicles (NGV’s) require less maintenance and run cleaner than conventional gasoline or diesel fueled vehiclesS Allow fleets to meet strict emissions regulations in densely populated areasS FUEL COST SAVINGS!
  4. 4. The Math Works-CNGS 1 gallon gasoline $3.61 = Gasoline Gallon Equivalent for CNG = $2.09* S Gasoline in Naples, FL – CNG in Pompano Beach, FL – Retail PricesS 1 gallon diesel $3.98 = Diesel Gallon Equivalent for CNG = $2.09* S Diesel in Naples, FL – CNG in Pompano Beach, FL – Retail PricesS Example: S ABC Trucking operates 20 heavy duty diesel delivery trucks S Each truck drives 150 miles per day and averages 5 MPG; 5 days per week S They currently use $620,880 of fuel per year @ $3.98 per gallon S If they convert to CNG their fuel savings per year could be $294,840 S Cost to convert 20 trucks to CNG: 20 trucks x $25k per conversion = $500,000 S Payback on conversion cost with NO grant money $500K/295K = 1.7 Years S Assumes all fueling is done at public stations S 7 year vehicle life cycle – Net fuel savings = $1,475,000
  5. 5. The Math Works-LNGS 1 gallon gasoline $3.61 = Gasoline Gallon Equivalent for LNG = $1.58* S Gasoline in Naples, FL – LNG based on existing contract for fleet in TexasS 1 gallon diesel $3.98 = Diesel Gallon Equivalent for natural gas = $1.58* S Diesel in Naples, FL – LNG based on existing contract for fleet in TexasS Example: S ABC Trucking operates 20 heavy duty diesel delivery trucks S Each truck drives 150 miles per day and averages 5 MPG; 5 days per week S They currently use $620,880 of fuel per year @ $3.98 per gallon S If they convert to LNG their fuel savings per year could be $374,400 S Fueling system lease $120,000 per year S Cost to convert 20 trucks to CNG: 20 trucks x $25k per conversion = $500,000 S Payback on conversion cost with NO grant money $500K/255K = 2 Years S Fueling done onsite with leased fueling system S 7 year vehicle life – Net fuel savings = $1,272,000
  6. 6. CNG Fueling InfrastructureS Can be mobile or skid mounted units for ease of relocation, deployment and installationS Can be permanent “Gas Station” style installationsS Can be “slow fill” or “fast fill” systemsS Systems consist of similar components regardless of design, only variance is size and fueling capacity
  7. 7. Fast Fill Design-CNGS System consists of meter, dryer, compressor, priority panel, storage, dispenser and credit card readerS Dispensing systems similar to traditional retail fueling stations for gasoline and dieselS Fast fill fueling accomplished through use of storage vessels and dispensersS Can have multiple islands for multiple vehiclesS Addition of credit card reader can make transaction seem like traditional station
  8. 8. Fast Fill Design-CNGS Examples of fast fill station layout:
  9. 9. Slow Fill Design-CNGS Dispensing systems in slow fill applications consist of multiple individual fueling connections which allow the system to fill all vehicles at one time as a wholeS No storage is used in slow fill applicationsS Costs can be lower depending on system design and sizeS No cost effective individual vehicle fuel measurement is readily available at this time
  10. 10. Slow Fill Design-CNGS Examples of slow fill station design and layout:
  11. 11. LNG Fueling InfrastructureS Can be mobile or skid mounted units for ease of relocation, deployment and installationS Can be permanent “Gas Station” style installationsS Slow fill system configurations are not typical with LNG as pumps are sized to deliver the volume required for a fleet’s requirementsS Systems consist of similar components regardless of design; only variance is storage size and pump capacity
  12. 12. Fast Fill Design-LNGS System consists of storage vessel, cryogenic pump, control panel, dispenser and credit card readerS Dispensing systems can be similar to traditional retail fueling stations for gasoline and dieselS Fast fill fueling accomplished through use of high speed cryogenic pump, storage vessel and dispensersS Can have multiple islands for multiple vehiclesS Addition of credit card reader can make transaction seem like traditional station
  13. 13. Fast Fill Design-LNGS Examples of fast fill station layout:
  14. 14. L-CNG Fueling InfrastructureS Integrates LNG and CNG systems into one hybrid design to utilize LNG as a fuel source while filling both LNG and CNG vehiclesS Solution for natural gas fueling needs where natural gas pipeline is not available for typical CNG stationS Uses in today’s market: Hydraulic fracturing, Oil and gas drilling, remote fleet conversions, industrial applications
  15. 15. Maintenance Shop InfrastructureS NFPA 52 codes require NGV maintenance facilities incorporate safety measures to reduce the potential for accidental fire or explosion S Continuous ventilation or automated ventilation activated by gas detection system S Air exchange rates of 1cu. ft./min S Electrical circuits installed in accordance with NEC Class I Div II requirements; Typically 18” envelope below ceiling is classified area S Audible and visual alarm installation required S Heating system style may need retrofit to eliminate open flame style heaters; Recommend radiant heating systems
  16. 16. Natural Gas EnginesS What is Bi-Fuel? S Commonly referred to as “switchable” systems; Engines that run on gasoline or natural gas, but not simultaneously; Engine will run on 100% gasoline or 100% natural gasS What is Dual Fuel? S Dual fuel systems are diesel engines that run on a mixture of natural gas and diesel; Natural gas is injected into the diesel engine to replace a certain amount of diesel; Can still run on 100% diesel; Cannot run on 100% natural gasS What is Dedicated Fuel? S Dedicated natural gas engines are only designed to burn natural gas as a fuel; These cannot burn diesel or gasoline
  17. 17. Natural Gas Engines (Cont’d)S Light Duty Solutions S Direct new OEM natural gas vehicles factory equipped for natural gas fuel S Conversion of older engines as per EPA guidelinesS Medium Duty Solutions S International Navistar DT466 T444E repowered to Phoenix 7.6L and 7.3L S Landi Renzo/Baytech CNG conversion of GM and Isuzu engines S VariousS Heavy Duty Solutions S Cummins Westport ISL G, ISX12, ISX S American Power Group conversions S Various
