EERE Releases Well-to-Wheels and Life Cycle Cost Analysis of Light-Duty Vehicles
June 13, 2013
The U.S. Department of Energy’s Office of Energy Efficiency and Renewable Energy (EERE) recently released peer-reviewed documentation detailing the updated well-to-wheels greenhouse gas (GHG) emissions and petroleum energy usage as well as the life cycle cost analysis for advanced technology vehicles that could be deployed in approximately 2035.
EERE’s Sustainable Transportation Office, consisting of Vehicle Technologies, Fuel Cell Technologies, and Bioenergy Technologies, updated and documented the records, which document the assumptions and results of analyses based on several fuel/vehicle pathways, including advanced internal combustion engine vehicles and other advanced vehicles (hybrid electric, plug-in hybrid electric, battery electric, and fuel cell electric vehicles). The fuels assumed for the GHG analysis included gasoline with 10% ethanol blended in (E10), diesel, E85 from corn and corn stover, "drop-in" gasoline from biomass, natural gas, electricity (U.S. grid electricity, U.S. renewable electricity), and hydrogen from a variety of feedstocks. The analyses used the latest versions of applicable models (maintained by Argonne National Laboratory, the National Renewable Energy Laboratory, and Sandia National Laboratories) and assumptions for technology advances based on DOE technical and cost targets that have been extensively reviewed by technical experts.
EERE pursues a broad portfolio of transportation technologies with the potential to significantly reduce GHG emissions and petroleum consumption to reduce the nation’s reliance on foreign oil and diversify the national energy portfolio.
