CO2 Capture and Storage Via In Situ Carbonation in Peridotite
Tuesday November 24th
Room 417 Schermerhorn Hall
Summary: Inspired by natural, geological examples in which CO2 from the atmosphere and from ground water combines with magnesium and calcium from exposed mantle peridotite to form solid carbonate minerals, my colleagues and I are developing ways to accelerate this process. Our goal is to achieve CO2 uptake rates of billions of tons per year, a significant amount given current human emissions of around 30 billion tons of CO2 per year, primarily as a result of fossil fuel use.
Peter Kelemen is Arthur D. Storke Memorial Professor of Earth and environmental sciences. His fields of interest include CO2 capture and storage via in situ mineral carbonation in peridotite and basalt; melting and reactive melt transport in the Earth's mantle and lower crust; igneous processes in forming the Earth's crust; ductile deformation and evolution of the lower crust; subduction zone geotherms and the mechanisms for intermediate depth earthquakes. Professor Kelemen attended Dartmouth as an undergraduate and completed his graduate studies at the University of Washington. He is based at the Lamont-Doherty Earth Observatory where his research oftens involves collaborating with geophysicists whom he credits with having led him into the world of geodynamics.
Future talks are scheduled for Tuesdays from 12:15-1:00pm in Room 417 Schermerhorn Hall. Attendees are welcome to bring their lunch.
All are welcome to attend!
