Alternative Fuel Fleets

TRB's Airport Cooperative Research Program (ACRP) Synthesis 85: Alternative Fuels in Airport Fleets is designed to assist airport operators in analyzing complex procurement, operational, and environmental decisions when considering alternative fuels in airport fleets. Airports own and contract fleets to transport passengers, staff, and goods by on- and off-road vehicles. Although most transportation fuels are consumed by aircraft, using alternative fuels in airport fleets is one opportunity airports have to control emissions and fuel costs and potentially reduce maintenance. The report compiles information on eight alternative fuels, including biodiesel, renewable diesel, compressed natural gas, renewable natural gas, liquefied natural gas, liquefied petroleum gas, hydrogen, and electricity. Ethanol and hybrid-electric vehicles (HEVs) are not included in this report because the driving experience and refueling operations associated with ethanol and HEVs are well understood and documented elsewhere.

Written primarily for fleet management personnel with purchasing, maintenance, or operations responsibilities, Alternative Fuels: Emissions, Economics, and Performance provides essential information for those who are considering adding alternatively-fueled vehicles to their fleets. Readers will gain a solid understanding of the fundamentals of alternative fuels and the factors that need to be considered when evaluating their use. No prior knowledge of alternative fuels is necessary. Basic information on the various alternative fuels and objective data on the costs of converting, fueling, and operating alternatively-fueled vehicles is covered in this book. Fuel cost, performance, reliability, and availability are addressed. The book also discusses the 1990 amendments to the Clean Air Act and the 1992 Comprehensive National Energy Policy Act. A summary of Texas' state law, considered to be representative of state legislation on alternative fuels and a glossary of key terms, are also included. Eight chapters cover: Review of Engine Technology; Characteristics of Alternative Fuels; Conversion of Spark Ignition Engines; Conversion of Compression Ignition Engines; Refueling Facilities; Legislation and Policies; and Cost Considerations. The book is also an ideal introduction to the topic for legislators, administrators, educators, and anyone interested in learning more about alternate fuels.
