    EWGP--a work in progress....
    (2007-03-09) Fischer, John E
    The need for energy affects almost every aspect of modern society. Indeed, the advent of coal as a widely-used energy source is sometimes viewed as the spark that started the Industrial Revolution. However, we are about to enter a new era due to increased competition from developing nations for the world's dwindling energy supplies and to the growing recognition that our current energy usage is unsustainable and is affecting the world's climate. It is apparent that research on energy-related issues will become increasingly important in the coming years.

    Carbide-Derived Carbons with Tunable Porosity Optimized for Hydrogen Storage
    (2007-05-16) Fischer, John E; Gogotsi, Yury; Yildirim, Taner
    Relevance: Improvements in gravimetric and volumetric capacity were realized by processes which increase pore volume, heat of adsorption and powder density. Volumetric capacity was more than doubled by rolling peels with PTFE binder and pellet pressing. Even larger gains may be achieved with bulk precursors. Approach: A suite of post-processing strategies were developed and optimized for specific precursors. Technical Accomplishments and Progress: Excess H2 adsorption over 4.3 wt.% and 0.034 kg/L was demonstrated in as-produced CDC having a moderate SSA and pore volume @ (77K, 55 atm). Max heat of H2 adsorption up to 11 kJ/mol (with average values ~ 8 kJ/mol) demonstrated. Proposed Future Research: Further science-based modification of CDC porosity, microstructure and chemistry for improved H2uptake.

    The Advanced Energy Initiative: Challenges, Progress, and Opportunities
    (2007-03-09) Milliken, JoAnn; Yuzugullu, Elvin; Stanford, Joseph
    This talk will address hybrid vehicles and battery technology, ethanol as a fuel, and hydrogen fuel cells, the ability of these technologies to reduce oil dependence and the challenges for each approach, and the progress made. Stationary power generation, solar buildings, and portable power fuel cells will also be discussed. The presentation will be at a programmatic level and will touch on the applied research and technology development opportunities under the Advanced Energy Initiative.

    The Global Energy Challenge
    (2007-03-09) Crabtree, George
    The expected doubling of global energy demand by 2050 and its impact on supply, security, environment and climate challenge our traditional patterns of energy production, distribution and use. New routes are needed for the efficient conversion of energy from chemical fuel, sunlight, and heat to electricity or hydrogen as an energy carrier and finally to end uses like transportation, lighting, communication and information processing. Opportunities for efficient new energy conversion routes based on nanoscale materials will be presented, with emphasis on the sustainable energy technologies they enable.
