Overview

The climate and environmental impacts of ever-increasing atmospheric CO₂ require that CO₂ mitigation options be seriously and broadly pursued. Indeed, recent legislation will require California to dramatically reduce its CO₂ emissions in the coming decades. Efforts to increase energy efficiency and to expand non-fossil energy sources will help in this endeavor, but these approaches alone may be insufficient or too costly for the State to fully meet its emissions reduction goals. Therefore, the capture and sequestration of CO₂ emanating from fossil fuel combustion must also be considered as a mitigation tool for California, and a variety of such options are being investigated at Lawrence Livermore National Laboratory. Among these are low-cost means of chemically reacting CO₂ out of waste gas streams to form benign, storable or useable products. Specific applications to the energy, oil, and cement industries will be discussed.

Speaker Biography

Greg H. Rau, Ph.D. has for the past 25 years been actively engaged in biogeochemical research, especially using ¹³C and other naturally-occurring isotopes to address questions about carbon and nutrient cycling. More recently he has been investigating ways to exploit the natural chemical reactivity of carbon dioxide as a means of cost-effectively capturing and storing anthropogenic CO₂. One of these methods has been recently patented, and several others are pending. His Ph.D. was awarded from the University of Washington, and this was followed by postdoctoral experience at UCLA and at NASA-Ames Research Center. He is a longtime member of the American Geophysical Union and of the American Society of Limnology and Oceanography, and is a Fellow of the American Association for the Advancement of Science. A Senior Researcher with the Institute of Marine Sciences at the University of California, Santa Cruz since 1986, he is also affiliated with the Energy and Environment Directorate, Lawrence Livermore National Laboratory. Dr. Rau is fifth-generation native of Washington State, and lives with his wife, Vreni, in Castro Valley, California.
