  7. 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. • 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 Workshop: October 21-25, 2002 Report: March 2003 Dr. John Stringer, EPRI, Chair Dr. Linda Horton, ORNL, Co-Chair

  8. 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: 9M tons  40M tons (vehicles) • Storage: 4.4 MJ/L (10K psi gas)  9.72 MJ/L • Fuel cells: $3,000/kW $35/kW (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.

Highlighted areas will include improved and new materials and processes for hydrogen generation and storage, and for future generations of fuel cells for effective energy conversion.

  10. Basic Research for Hydrogen Production, Storage and Use Workshop • 125 Participants: • Universities • National Laboratories • Industries • DOE: SC and technology offices • Other Federal Agencies - including OMB, OSTP, NRL, NIST, NSF, NAS, USDA, and House Science Committee staff Remarks from News Reporters: American Institute of Physics Bulletin of Science Policy News Number 71 “Dresselhaus remarked that there were some “very promising” ideas, and she was more optimistic after the workshop that some of the potential showstoppers may have solutions.” “… solving the problems will need long-term support across several Administrations. Progress will require the cooperation of different offices within DOE, and also the involvement of scientists from other countries, …” C&E News June 9, 2003 “MOVING TOWARD A HYDROGEN ECONOMY” DOE Workshop Brings Together Scientists to Prioritize Research Needs for Switching to Hydrogen Economy.

  15. Planned BES Solicitation for Basic Research inSupport of the President’s Hydrogen Fuel Initiative • Approximately $21.5 million will be awarded in FY 2005, pending appropriations. • Separate solicitations for universities and FFRDCs are planned to be issued in May 2004. Preapplications are required. Tentative timeline: • July 15, 2004 Preapplications due • September 1, 2004 Decisions on preapplications sent to PIs • January 1, 2005 Full proposals due • June - July 2005 Awards made • The solicitation will request preapplications for innovative basic research proposals to establish the scientific basis that underpins the physical, chemical, and biological processes governing the interaction of hydrogen with materials. • Five high-priority research directions will be the focus of the solicitations: • Novel Materials for Hydrogen Storage • Membranes for Separation, Purification, and Ion Transport • Design of Catalysts at the Nanoscale • Solar Hydrogen Production • Bio-Inspired Materials and Processes • The distribution of funds between universities and FFRDCs awards and among the five focus areas will depend on the outcomes of the merit review process (http://www.sc.doe.gov/bes/peerreview.html).
