Abstract Highlights of selected research and development efforts at Oak Ridge National Laboratory funded by the Vehicle Technologies Program, Biomass Program, and Hydrogen and Fuel Cells Program of the Department of Energy, Office of Energy Efficiency and Renewable Energy; and the Department of Transportation. ORNL's Sustainable Transportation Program performs research and development leading to new vehicle and transportation system technologies. Highway transportation-light-, medium-, and heavy-duty vehicles-accounted for approximately 23% of U.S. greenhouse gas emissions and about 64% of all petroleum used in the United States in 2009. Energy use in highway transportation is expected to increase almost 21% by 2035 - from 11.1 to 13.4 million barrels per day oil equivalent. ORNL researchers are focusing on clean, efficient, and intelligent paths to reducing transportation fuel consumption and emissions, and achieving improved energy security. The research and development portfolio includes alternative fuels, more efficient vehicle components, lightweight materials, transportation electrification, and intelligent transportation systems and operations. Support of the Vehicle Technologies Program was highlighted by achievement of the U.S. DRIVE Partnership engine efficiency goal, use of neutron imaging techniques to study emission control devices and lithium distribution in battery electrodes, and advancing electric vehicle charging technologies including solar-assisted charging and wireless charging. Researchers are investigating innovative electric motor designs that reduce or eliminate the need for rare-earth permanent magnets, which are subject to market fluctuations in availability and cost. ORNL has worked with the Fuel Cell Technologies Program for several years on a nitrided material for use in fuel cell bipolar plates. In FY 2011, a collaborative effort with General Motors to explore manufacturability of the material by GM's existing stamping and welding practices was successful. A new multiyear project began to develop a stationary hydrogen storage system; preliminary engineering design has demonstrated that the integrated steel and prestressed concrete storage vessel can sustain 5,000 psi pressure based on industry codes and standards.
