Track 4: Environmental Analysis
Considerable research effort has been devoted to the analysis of energy cycle emissions of hydrogen use in transportation. In this research program, previous studies of lifecycle emissions and energy use will be compared and differences explicitly specified. Energy use and emissions of air pollutants and greenhouse gases will be analyzed for each pathway (including "business as usual"). Included in the analyses will be various feedstocks and fuels made off-board (alcohols, petroleum-based hydrocarbons, and hydrogen), and hydrogen produced on-board.

Project 1: The Private and Social Lifetime Cost of Fuel Cell, Hybrid, and Conventional Vehicles
In this research, the costs, energy use, and air pollutant and greenhouse emissions of hydrogen pathways will be analyzed and compared to other transportation energy and technologies.

Project 2: Lifecycle GHG Emissions Analysis
The task of developing and evaluating strategies to reduce emissions of urban air pollutants and greenhouse gases is complicated. There are many ways to produce and use energy, many sources of emissions in an energy lifecycle, and several kinds of pollutants (or greenhouse gases) emitted at each source.

Project 3: Environmental Analysis Associated with Hydrogen Pathways
This research will explore a number of typical or potentially promising hydrogen pathways (e.g., the coal to hydrogen pathway, the natural gas to hydrogen pathway, and the biomass to hydrogen pathway) from a lifecycle perspective.

Project 4: The Indirect Global Warming Potential of NOx Emissions
Although direct greenhouse gases (GHGs) have been researched and modeled extensively, indirect species, which influence climate by altering levels of direct species, have received relatively little attention. In this work, we estimate the CO2 equivalent impact of one of the most important, complex, and poorly understood indirect GHG, oxides of nitrogen (NOx). These results are of great interest to policy makers, as human activities (energy and fuel use) are a significant source of NOx emissions.
