Dr. David Dzombak: "Geologic Sequestration of CO2: Evaluating and Monitoring Seal Rock Integrity"

Start Date/Time: Thursday, January 27, 2011, 1:30 PM
Ending Date/Time: Thursday, January 27, 2011, 2:50 PM
Location: Kane 110

The leading technology under development for management of CO2 separated and captured from large emission sources, such as electric power plants, is carbon capture and geologic sequestration (CCS). Worldwide, only a few large scale tests of CCS have been conducted. In the US, the DoE has established seven regional partnership programs for large-scale testing of CCS, including evaluations of the rate of leakage from the storage reservoirs. This talk will present an overview of CCS and the challenge of risk assessment in relation to deployment of the technology. Potential mechanisms for leakage from CO2 storage reservoirs and performance objectives under consideration will be discussed. Results of research on seal rocks overlying saline reservoirs will be presented and the implications for assessment and monitoring of seal rock integrity in CCS will be discussed.

Dr. Dzombak is the Walter J. Blenko, Sr. Professor of Environmental Engineering in the Department of Civil & Environmental Engineering at Carnegie Mellon University and Director of the Steinbrenner Institute for Environmental Education and Research. He received a BA in Mathematics from Saint Vincent College, BS and MS degrees in Civil Engineering from Carnegie Mellon University and a PhD in Civil Engineering from MIT. He is a registered Professional Engineer in the Commonwealth of Pennsylvania, a Diplomate of the American Academy of Environmental Engineers, a Fellow of the American Society of Civil Engineers, and a member of the National Academy of Engineering. His research interests include water chemistry, fate and transport of chemicals in surface and subsurface waters, wastewater treatment and reuse, contaminated soil and sediment remediation, abandoned mine drainage remediation, and geologic sequestration of carbon dioxide.
