About Clean Cities



  Mission
  To advance the energy, economic, and environmental security of the United
  States by supporting local decisions to reduce petroleum use in transportation.

  Goal
  Reduce petroleum use by 2.5 billion gallons per year
         • Replacement
         • Reduction
         • Elimination

                                                                  Eliminate
  Accomplishments
         • Saved nearly 3 billion gallons of petroleum since 1993
         • Put more than 775,000 alternative fuel vehicles (AFVs) on the road
         • Installed more than 6,600 alternative fueling stations

Basics



  Natural Gas
  •     Hydrocarbons, predominantly methane (CH4)
  •     High octane rating

  •     Nontoxic, noncorrosive, and noncarcinogenic
  •     Not a threat to soil, surface water, or groundwater
  •     Lower ozone-forming emissions than gasoline

  •     Extracted from gas and oil wells
  •     Existing pipeline distribution system

Basics: CNG and LNG


  Compressed Natural Gas (CNG)
  •     Stored in onboard tanks under high
        pressure
  •     Fuel economy similar to gasoline
  •     1 GGE = 5.7 lb CNG


  Liquefied Natural Gas (LNG)
  •     Kept at cold temperatures
  •     Stored in double-wall, vacuum-insulated
        pressure vessels
  •     Heavy-duty vehicles
  •     1 GGE = 1.5 gal LNG

Basics: Natural Gas Vehicles


  Dedicated Natural Gas Vehicles (NGV)
  •     Run only on natural gas
  •     Better performance
  •     Lower emissions
  •     Increased cargo capacity


  Bi-fuel NGVs
  •     Two fueling systems
          o    Natural gas
          o    Gasoline
  •     Fueling flexibility


  Dual-fuel NGVs
  •     Run on diesel and natural gas
  •     Heavy-duty vehicles only

 Basics: Natural Gas Vehicles



A: Gas fill valve                 E: Regulator
B: Cylinders                      F: Natural gas solenoid valve
C: Master manual shut-off valve   G: Fuel-injection system
D: High-pressure fuel line

    Use: Fleet Applications

Light-Duty NGVs
•    Suitable for light-duty needs in private and
     government fleets
•    Honda Civic GX


Medium-Duty NGVs
•    Vans and shuttles
•    Airports and taxi fleets


Heavy-Duty NGVs
•    Refuse haulers
•    Transit buses
•    School buses
•    Long-haul trucks
•    Street sweepers
•    Snowplows                                      Natural Gas Vehicles for America
                                                    www.ngvamerica.org
•    Short-haul delivery trucks

    Clean Cities / 10
Use: Fueling Stations


  Offsite, Public Access
  •     Utilize an existing public station
  •     Operated by retailer, utility, or fleet
  •     Anchor fleet or pool of multiple fleets


  Onsite, Private Access
  •     Exclusive use by fleets
  •     Time-fill stations always private access


  Onsite, Public Access
  •     Often located outside of restricted areas
  •     Benefit from economy of scale
  •     Promotes public use of NGVs
  •     Must have fast-fill capabilities for public




Clean Cities / 11
Use: Station Ownership and Operation

  Fleet-Owned and -Operated
  •     Fleet works with vendors on station development
  •     Fleet owns and operates station


  Outsourced to Independent Provider
  •     Outside development, ownership, and operation
  •     Fleet provides demand threshold
  •     Long-term price agreement
  •     Public access possible


  Fleet-Owned, Contractor-Operated
  •     Reduces fleet risk
  •     Fleet relies on experienced operator
  •     Usually a 5-7 year contract




Clean Cities / 12
Use: CNG Fueling


  Time-Fill Fueling
  •     Good for centrally-based fleets with consistent schedules
  •     CNG is dispensed slowly, often overnight
  •     Lower cost investment


  Fast-Fill Fueling
  •     Fueling takes place in minutes
  •     Necessary for public-access stations
  •     Good for vehicles with little downtime


  Combo-Fill Fueling
  •     Time-fill and fast-fill
  •     More flexibility in fueling




Clean Cities / 13
Use: LNG Fueling


 Mobile Fueling
 •     Tanker truck with metering and dispensing equipment
 •     Provides temporary fueling option


 Starter/Containerized System
 •     Complete fueling station, including storage tank, dispensing,
       metering, and required containment
 •     Turn-key solution


 Custom Station
 •     Larger storage tanks
 •     Multiple dispensers
 •     LNG and/or CNG dispensing




Clean Cities / 14
Use: Getting Started


  Questions to Ask
  •     How many vehicles will be fueled each day?
  •     How much fuel will each vehicle need?
  •     When and how often will vehicles need to be fueled?
  •     What are the site development requirements?




Clean Cities / 15
Use: Getting Started

  Prepare Fleet Inventory and Replacement Schedule
  •     Identify vehicle replacement potential
  •     Determine station sizing plan


  Explore Your Options
  •     Contact vehicle vendors
  •     Contact equipment vendors
  •     Meet with station developers


  Visit Existing Sites
  •     Fast-fill and time-fill
  •     Private and public


  Ask Questions
  •     Clean Cities coordinators
  •     Station developers
  •     Vendors
