  1. Objectives • Explain how to implement green fleets • Learn about incentives for utilizing idle reduction technologies and strategies • Learn about the availability and cost of idle reduction technologies and strategies • Identify the advantages of idle reduction technologies and strategies • Understand the performance of vehicles with idle reduction technologies

  2. Greening of Fleets • Why use green fleets? • Reduce operating costs • Reduce greenhouse gas emissions • Improve corporate image

  3. How to Implement Green Fleets • Get buy-in • Create long-term objectives • Avoid setting reduction goals in absolute numbers • Anticipate obstacles • Move slowly • Improve vehicle use • Track and report progress

  4. Idle Reduction in Fleets • Petroleum and emissions reduction strategy • Idle = speed at which ICEs rotate under no throttle or load • Tachometer displays engine speed • Smooth engine operation for vehicle acceleration from stop and adequate oil pressure

  5. Transportation and convenience idling • Technologies, policies, practices to reduce engine idle time • Strategies and technologies to reduce both transportation and convenience idling Figure 1: The engine tachometer showing a vehicle’s idle speed. Source: NAFTC.

  6. Idle Reduction Strategies • Any reduction in idle time = fuel savings • Avoid traffic by planning trips • Fleet guidelines to reduce idle time • Reductions = immediate savings

  7. Idle Reduction Technologies • New technologies, improved fuel economy and reduced emissions • Light-, medium-, and heavy-duty vehicle fuel savings • Idle shutoff functions, mild hybrid technologies • APUs for long haul trucks • TSE implementation

  8. Incentives for using Idle Reduction in Fleets • Incentives • Partnership initiatives and pooled resources • Financial subsidiaries • Informational tools • Initial cost vs. federal and state incentives • American Recovery and Reinvestment Act (ARRA) • Clean Cities Program

  9. Tax Incentives • Federal and state incentives for alternative fuels and advanced technology vehicles • Implementation of idle reduction equipment • Funding and partnership opportunities for idle reduction technologies

  10. For a list of qualifying tax exempt idle reduction equipment, visit http://www.epa.gov/smartway/technology/excise-tax.htm.

  11. Federal Grant Funding • Federal government = largest grant provider • U.S. Department of Energy (DOE) • U.S. Department of Transportation (DOT) • Environmental Protection Agency (EPA) • U.S. Department of Agriculture (USDA)

  12. State Grant Funding • State Energy Office (SEO) • National Association of State Energy Officials directory • Alternative Fuels Data Center map • To find state-specific information, visit www.afdc.energy.gov/afdc/laws/state

  13. Idle Reduction Laws • Generally limit the time a vehicle is idling • No idle zones • Schools • Individual rules for each city/area

  14. To search local idle restrictions, visit http://www.afdc.energy.gov/afdc/vehicles/idle_reduction_laws.html.

  15. Idle Reduction Availability and Cost • Light-Duty • Block Heaters • Utilize grid power to maintain engine temperature • Heavy-duty vehicles • Reduce problems associated with cold starts

  16. Light- and Medium-Duty • Mild Hybrids • Idle shutoff function • Utilizes small battery pack and MG • Small amounts of energy • Onboard energy storage

  17. Light-Duty • New Idle Shutoff Technologies • Reduced energy needed to restart engine • One way clutch technology • Micro-hybrid systems

  18. Heavy-Duty • HOS requirements • Average truck idles for more than 1,900 hours annually • Truck idling consumes more than three billion gallons of diesel annually

  19. Heavy-Duty • Truck Stop Electrification (TSE) • Electrified parking spots at truck stops • Enable drivers to meet rest requirements without idling Figure 2: Long haul truck utilizing single system electrification. Source: IdleAir.

  20. To find an electrified truck stop in your region, the DOE hosts a site locator searchable by zip code. It can be found by visiting http://www.afdc.energy.gov/afdc/locator/tse.

  21. Heavy-Duty • Truck Stop Electrification (TSE) • Single-system vs. dual-system • Single-system offers HVAC, electricity, internet, cable • Unit is placed in passenger window • Dual-system requires onboard equipment • Driver plugs truck into outlet to power onboard equipment

  22. Heavy-Duty • Onboard Equipment • Powered by external electrical source or existing fuel system • More efficient than allowing the engine to idle

  23. Heavy-Duty • Onboard Heating • Direct-fired = small furnaces • Consume only a small amount of fuel per hour • Coolant heater = heat transfer system • Can be used to heat cabin and warm engine in cold climates

  24. Heavy-Duty • Onboard Cooling • Thermal storage, battery-electric air conditioners • Thermal storage: energy is stored during normal operation, used at a later time to cool cab • Battery-electric air conditioners: powered by onboard batteries that are charged at truck stops • Both produce zero local emissions

  25. Heavy-Duty • Auxiliary Power Units • Small vehicle-mounted systems • Electrical generator powered by an internal combustion engine • Powers accessories, HVAC • Heat recapture from ICE • Rechargeable battery packs

  26. Strategies • Determine appropriate warm-up time • Know the equipment being utilized in your vehicle • Turn engine off

  27. Cost • Tax benefits for hybrid vehicles • Heavy-duty vehicle modification incentives • Fuel cost savings will help cover any initial investment over time

  28. Idle Reduction Advantages • Reduced fuel consumption • Fewer vehicle emissions • Lower operating costs • Increased engine life • No-cost implementation of strategies

  29. Things to Consider • Possible capital investment • Personal convenience may be compromised

  30. Idle Reduction Performance • Extended engine life • Extended idling adds unnecessary wear to engine components • Fuel savings helps offset capital costs • Exemptions for added weight from APUs, etc. • “Green” branding of fleets

  31. Performance Summary Better fuel economy, an idling vehicle not in motion achieves 0 mpg Reduced emissions Similar performance to conventional vehicles May lead to extended engine life

  32. Test Your Knowledge • True or False: There are idle reduction strategies available for fleet managers that require little to no cost to implement. • An average long-haul truck spends over______ hours idling per year. • There are two types of idling. They are: ______________ and ______________. • True or False: States and cities are not allowed to implement laws limiting the idling time or location of idling vehicles.
