Recent Advances in CO2 Storage Science and Engineering
Chemical Engineering Theatre G20
The University of Melbourne, Parkville
Special Seminar: Prof Sally Benson
Geological storage of carbon dioxide has the potential for significant reductions in greenhouse gas emissions. While the fundamental scientific underpinnings of CO2 storage build on a century-long exploration of the physics of multiphase flow in porous media, there are aspects that remain unexplored and warrant further investigation. In this talk, I will review recent experimental and theoretical research on multiphase flow of CO2 and brine in heterogeneous rocks, pore and continuum scale studies of the stability of residually trapped CO2, and monitoring CO2 migration using pressure transient data. The implications of the finding from advances in CO2 storage science will we discussed for real-world projects.
Presenter: Dr Sally M Benson
Co-Director, Precourt Institute for Energy
Director, Global Climate and Energy Project
Professor, Energy Resources Engineering, Stanford University
Sally M Benson joined Stanford University in 2007. She holds three appointments at Stanford: professor of energy resources engineering in the School of Earth, Energy & Environmental Sciences; co-director of the Precourt Institute for Energy, the campus-wide hub of energy research and education; and director of the Global Climate and Energy Project (GCEP). An internationally recognized scientist, Benson is responsible for fostering cross-campus collaborations on energy and guiding the growth and development of a diverse research portfolio.
Prior to Stanford, Benson was at Lawrence Berkeley National Laboratory, a leading research center supported by the U.S. Department of Energy and managed by the University of California. There she held a variety of key positions, including deputy director of operations and director of the Earth Sciences Division.
A groundwater hydrologist and reservoir engineer, Benson is regarded as a leading authority on carbon capture and storage, and emerging energy technologies. In 2012, she served as a convening lead author of the Global Energy Assessment, a multinational project coordinated by the International Institute for Applied Systems Analysis.
Benson and her GCEP colleagues have conducted a groundbreaking series of net energy analyses calculating the energetic costs of wind turbines, solar photovoltaics and grid-scale renewable energy storage. She also leads a research laboratory that studies geologic carbon dioxide (CO2) sequestration in saline aquifers. In 2005, she served as a coordinating lead author of a special report on CO2 capture and storage published by the Intergovernmental Panel on Climate Change (IPCC). Professor Benson contributed to the reports of the IPCC, which was awarded the Nobel Peace Prize in 2007.
The author or co-author of over 160 scientific publications, she has delivered more than 200 invited talks and has testified at U.S. Congressional hearings on climate change technology and CO2 sequestration.
Benson received a B.S. in geology from Barnard College at Columbia University, and an M.S. and Ph.D. in materials science and mineral engineering from the University of California-Berkeley.
