Considerable research effort has been devoted to the analysis of energy cycle emissions of hydrogen and alternative fuels for use in transportation. In this research program, previous studies of lifecycle emissions and energy use are compared and differences explicitly specified. Energy use and emissions of air pollutants and greenhouse gases are analyzed for each alternative fuel pathway. This research features the incorporation of alternative fuel vehicles into the current Advanced Vehicle Cost and Energy Use model (AVCEM) and Lifetime Emissions Models (LEM), as well as the Social Cost Calculator (SCC).
