In order to fully evaluate energy and emission benefits of advanced vehicle technologies and new transportation fuels, well-to-wheels (WTW) analysis becomes necessary, since energy losses and emissions occur during the fuel production stage as well the vehicle operation stage. With DOE support, Argonne National Laboratory has been developing the Greenhouse gases, Regulated Emissions, and Energy use in Transportation (GREET) model for WTW analyses since 1995. The GREET model enables analysts to evaluate WTW energy and emission effects of various vehicle/fuel systems by including fuel production activities and vehicle operation activities. In addition, the GREET model helps examine energy and emission effects of producing different materials such as steel and aluminum for vehicle production.
With the GREET model, Argonne has analyzed WTW energy and emissions of advanced vehicle/fuel systems for Department of Energy and industries. Argonne applied the GREET model to analyze energy use and emissions of propulsion systems such as hybrid electric vehicles and fuel-cell vehicles and fuels such as gasoline, diesel, hydrogen, and biofuels. In particular, Argonne has examined emissions of greenhouse gases and criteria pollutants and energy use for petroleum and fossil energy use for various vehicle/fuel options. This presentation summarizes updated results of Argonne’s well-to-wheels energy and emission evaluations with the GREET model for biofuels and other fuels such as coal to liquids.
