The New York State Energy Research and Development Authority (NYSERDA), under its Alternative Fuels for Vehicles Fleet Demonstration Program (AFV-FDP), established a demonstration of light-duty dedicated propane vehicles operated by the New York State Office of Parks, Recreation and Historic Preservation (OPRHP). The fleet of five converted trucks began operation in 1993 with the cooperation of the New York Propane Gas Association, which provided the propane systems, and Texaco Research & Development which funded annual emissions testing. The vehicles accumulated 122,000 kilometers (76,000 miles) of operation on propane during the demonstration. Data were collected on fuel consumption, driveability, acceleration, maintenance, and emissions. This paper reports on the transition to propane fuel operations, the findings of the emissions tests, and the service and support experiences during the demonstration.

This book presents the fundamentals needed to understand the physical and chemical properties of alternative fuels, and how they impact refueling system design and the modification of existing garages for safety. It covers a wide range of fuels including alcohols, gases, and vegetable oils. Chapters cover: Alternative Fuels and Their Origins Properties and Specifications Materials Compatibility Storage and Dispensing Refueling Facility Installation and Garage Facility Modifications and more

With the vitality and economic growth of the U.S. being linked to affordable transportation, the use of alternative fuels is beginning to play a larger role. The use "alternative fuel" has been used to describe any fuel suggested for use in transportation vehicles other than gasoline or diesel. Since 1998, more than half of the petroleum the U.S. economy requires has been supplied by imports. In addition, the climatological and scientific community has warned that increasing concentrations of greenhouse gases in the atmosphere will cause global change. Alternative Fuels examines the accepted alternative fuels, providing historical background, physical and chemical properties, production technology, and forecasts for each fuel. Alternative transportation fuels addressed include: methanol, ethanol, propane, natural gas, biodiesel, hydrogen, and electricity. Chapters include: The Argument for Alternative Fuels Methanol Ethanol Propane Natural Gas Electricity and more
