GLRPPR Sector Resource: The Greenhouse Gases, Regulated Emissions, and Energy Use in Transportation (GREET) Model

Title:
The Greenhouse Gases, Regulated Emissions, and Energy Use in Transportation (GREET) Model

Abstract:
To fully evaluate energy and emission impacts of advanced vehicle technologies and new transportation fuels, the fuel cycle from wells to wheels and the vehicle cycle through material recovery and vehicle disposal need to be considered. Sponsored by the U.S. Department of Energy's Office of Energy Efficiency and Renewable Energy (EERE), Argonne has developed a full life-cycle model called GREET (Greenhouse gases, Regulated Emissions, and Energy use in Transportation). It allows researchers and analysts to evaluate various vehicle and fuel combinations on a full fuel-cycle/vehicle-cycle basis. GREET was developed as a multidimensional spreadsheet model in Microsoft Excel. This public domain model is available free of charge for anyone to use. For a given vehicle and fuel system, GREET separately calculates: Consumption of total energy (energy in non-renewable and renewable sources), fossil fuels (petroleum, natural gas, and coal together), petroleum, coal and natural gas; Emissions of CO2-equivalent greenhouse gases - primarily carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O); Emissions of six criteria pollutants: volatile organic compounds (VOCs), carbon monoxide (CO), nitrogen oxide (NOx), particulate matter with size smaller than 10 micron (PM10), particulate matter with size smaller than 2.5 micron (PM2.5),and sulfur oxides (SOx). GREET includes more than 100 fuel production pathways and more than 70 vehicle/fuel systems. These vehicle/fuel systems cover all major vehicle technologies in the market and R&D arena: Conventional spark-ignition engines; Direct-injection, spark-ignition engines; Direct injection, compression-ignition engines; Grid-independent hybrid electric vehicles; Grid-connected (or plug-in) hybrid electric vehicles; Battery-powered electric vehicles; Fuel-cell vehicles.
