Transportation fuels and vehicles : background paper for the spirit of innovation in transportation conference held at the John A. Volpe National Transportation Systems Center, Cambridge, Massachusetts June 24-25, 1999.
Environmental concerns are currently the primary driver of innovation in the area of Transportation Fuels and Vehicles. Road vehicle emissions are a significant determinant of urban air quality and produce a very substantial quantity of carbon dioxide, with potentially serious implications for global climate change. Long-term petroleum availability and the efficiency of the transportation system are also imporant considerations. The dominant role of highway vehicles in both passenger and freight trasnportation in the U.S. makes the exploration of alternative fuel-propulsion systems particularly important. It is questionable whether the impressive rate of vehicle emission reduction and efficiency increases of recent decades can be extended without major innovation in the fuel-vehicle system.
