Analysis of Exergy and Carbon Flows in Natural and Human Systems

Exergy is the useful portion of energy that allows us to do work and perform energy services. It declines as energy is converted from one form to another and can be all destroyed if the ultimate product is ambient heat. This talk will present an analysis of data collected on the destruction of exergy and the flow of carbon in global energy systems. These data have been summarized in a set of exergy and carbon flow charts. The major destructions of exergy, the exergy efficiency of human energy processes, and the processes most associated with atmospheric carbon emissions will be described. Using this data, one can uncover the energy transformations where improvements in exergy efficiency will have the greatest impact in reducing CO2 emissions, and then identify opportunity areas for further energy research.

Dr. Richard Sassoon is the Managing Director of the Global Climate and Energy Project where he coordinates and oversees all day-to-day operations of the Project. GCEP is a unique partnership between academia and industry led by Stanford with the mission of conducting fundamental research on technologies that will permit the development of global energy systems with significantly lower greenhouse gas emissions. At GCEP, he also leads its efforts in the area of energy systems analysis. Prior to joining GCEP, Dr. Sassoon was Senior Scientist and Assistant Vice President at Science Applications International Corporation, where he worked with the U.S. Department of Energy in strategic planning and management of its environmental research programs. He has also spent many years researching the area of photochemical solar energy conversion and storage systems. Dr. Sassoon received his B.Sc. in Chemistry from Leeds University, and his Ph.D. in Physical Chemistry from the Hebrew University of Jerusalem in Israel.
