1 Clean Cities / 1 COALITION NAME Natural Gas Vehicles Overview Presenter Title Date

2 Clean Cities / 2 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 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

3 Clean Cities / 3 Clean Cities Coalitions Nearly 100 coalitions in 45 states 775,000 AFVs using alternative fuels 6,600 fueling stations

4 Clean Cities / 4 Natural Gas Hydrocarbons, predominantly methane (CH 4 ) 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

5 Clean Cities / 5 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: CNG and LNG

6 Clean Cities / 6 Basics: Natural Gas Vehicles

7 Clean Cities / 7 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

8 Clean Cities / 8 Basics: Natural Gas Vehicles A: Gas fill valve B: Cylinders C: Master manual shut-off valve D: High-pressure fuel line E: Regulator F: Natural gas solenoid valve G: Fuel-injection system Adapted from Compressed Natural Gas: A Suite of Tutorials.

9 Clean Cities / 9 Benefits and Considerations Public Health and Environment Lower greenhouse gas (GHG) emissions Lower particulate pollution Lower carcinogens Energy Security Plentiful in U.S. Existing infrastructure Driving Range Shorter than gasoline Comparable power and speed Deployment Proven and established 114,000 natural gas vehicles in U.S. in 2008

10 Clean Cities / 10 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 Short-haul delivery trucks Use: Fleet Applications Natural Gas Vehicles for America

11 Clean Cities / 11 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 Use: Fueling Stations

12 Clean Cities / 12 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 Use: Station Ownership and Operation

13 Clean Cities / 13 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 Use: CNG Fueling

14 Clean Cities / 14 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 Use: LNG Fueling

15 Clean Cities / 15 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? Use: Getting Started

16 Clean Cities / 16 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 Use: Getting Started
