Energy Science and Technology Topical Conference: Energy underpins many, if not all, aspects of life. With the ever-increasing demand for energy comes the concern over the inevitable end of our carbon-based fossil fuels. Our “science and technology” have provided solutions to many of our past “crises,” however, will we be able to meet the expected incredible needs in our constantly developing and expanding world? The topic of energy certainly has close links with all activities of AVS - from biological science to surface chemistry and catalysis to electronic materials, and manufacturing challenges. There are immense R&D opportunities for our science and technology community to continue to provide solutions. This special seminar will focus on the issues related to energy for sustainable mobility. Representatives from car companies will discuss their concepts of vehicles that will transport us in the future. They will address challenges in the areas of system performance and manufacturability, as well as consumer expectations. In addition, experts from the areas of hydrogen and biomass fuels will present a focus on which fuel will be the most responsible, economical, and environmentally sound for these new vehicles. To round off the session, the perspective of the U.S. Department of Energy on these very challenging issues will be presented.
