The Energy Problem § Fossil fuels provide about 85% of the world’s energy. Although reserves are adequate for the next 50 to 100 years, there are two reasons to seek alternative energy sources now: § The largest reserves of one of the most important fossil fuels, petroleum, reside outside the U. S. in politically unstable regions of the world. § The production and release of carbon dioxide into the atmosphere pose the risk of global warming. Workshop: October 21 -25, 2002 Report: March 2003 Dr. John Stringer, EPRI, Chair Dr. Linda Horton, ORNL, Co-Chair § All of the alternatives to fossil fuels, even when summed together, today make at best marginal contributions to energy production. § The BESAC report highlighted 37 proposed research directions, most of which already were represented in the BES portfolio of activities 7
Basic Research Needs for the Hydrogen Economy § There exists an enormous gap between present state-of-the-art capabilities and requirements that will allow hydrogen to be competitive with today’s energy technologies: § Production: 9 M tons 40 M tons (vehicles) § Storage: 4. 4 MJ/L (10 K psi gas) 9. 72 MJ/L § Fuel cells: $3, 000/k. W $35/k. W (gasoline engine) § Major R&D efforts will be required: § Simple improvements of today’s technologies will not meet requirements § Technical barriers can be overcome only with high risk/high payoff basic research § Research is highly interdisciplinary, requiring chemistry, materials science, physics, biology, engineering, nanoscience, computational science. § Basic and applied research should couple seamlessly. Workshop: May 13 -15, 2003 Report: Summer 2003 This was the first comprehensive study devoted entirely to the basic research needs associated with a future hydrogen economy.
