Clean Cities / 11 Vehicles: Where to Find Available Models?

Clean Cities / 12 Vehicles: CNG Tanks and Safety Images: NREL Image Gallery #18210, #00089, #03755 Helpful Resource: When properly operated and maintained, natural gas infrastructure and vehicles are unlikely to present any danger to drivers or passengers. NFPA 52, the Vehicular Gaseous Fuel Systems Code, spells out specific safety requirements for natural gas vehicles (NGVs) and their fueling facilities.

Clean Cities / 13 Case Study #1: Kansas City Public Schools Invests in CNG Buses Just the Numbers CNG School Buses: 50 Fuel Cost Savings: $20,000 to $30,000 per month Petroleum Displacement: 15,000 gallons of diesel fuel per month “Our primary motivation for doing this was fuel costs. They're high, and getting higher, and we're facing budget cuts. Also, CNG is a clean fuel and benefits the environment.” —George Taylor, Director of Transportation Replaced 47 of its 120 buses with a transit-style bus with a CNG engine; also converted three Type A buses to CNG $3.6 million in grant funding for the buses, a fueling station, a mobile refueler, and maintenance facility modifications Image and More Information: AFDC Case Study Search, Kansas City Kansas Public Schools Invests in CNG Buses,

Clean Cities / 14 Case Study #2: Groot Industries Shows Natural Gas Refuse Truck Benefits Just the Numbers CNG Refuse Trucks: 20 Fuel Cost Savings: 40% Simple Payback: 3 to 6.2 years (depending on fuel, vehicle, and infrastructure cost) Independent solid waste management company serves 250,000 customers Committed to natural gas due to emissions and noise benefits Purchased refuse trucks with the Cummins ISL-G CNG engine Funded by American Recovery and Reinvestment Act and the State of Illinois Image and More Information: Argonne National Laboratory, Case Study – Compressed Natural Gas Refuse Fleets,

Clean Cities / 15 Case Study #3: LNG Allows for Cleaner Refuse Collection in Sacramento Just the Numbers LNG Refuse Haulers: 113 LNG Fuel Use: 1 million gallons per year GHG Reductions: 1,900 tons per year (11%) “It has never been easier to migrate to NGVs. The network of natural gas fueling stations and the natural gas engine offerings are currently experiencing tremendous growth.” ─Keith Leech, Fleet Manager Replaced 113 side- and rear-loader refuse haulers with LNG Partners: Sacramento Clean Cities, local air district, local fleets, and vehicle and engine manufacturers Reductions in life cycle GHG emissions, maintenance costs, and noise Image and More Information: AFDC Case Study Search, LNG Allows for Cleaner Refuse Collection in Sacramento,

Clean Cities / 24 ? Based on my fleet inventory and replacement schedule, what is the vehicle replacement potential? What vehicle, equipment, and station development vendors exist? Are there fueling stations in my area? Are they public or private? Can I visit? What support can my local Clean Cities coalition provide? 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 maintenance facility and fueling infrastructure site development requirements? What federal, state, and local incentives are available? Getting Started: Questions to Ask Image: NREL Image Gallery #28005 Helpful Resource: The AFDC Laws and Incentives Search provides information about available state and federal incentives for NGVs and infrastructure.
