Seminar: Putting away CO2 for good – carbon sequestration in Icelandic basalts

Reducing atmospheric CO2 emissions to fight climate change is one of the prime challenges of our times.

Carbon capture and storage (CCS) can contribute towards decarbonization of the global economy. The success of this solution depends on the ability to safely and permanently store CO2. This study demonstrates for the first time the permanent disposal of CO2 as environmentally benign carbonate minerals in basaltic rocks. It was found that over 95% of the CO2 injected into the CarbFix site in Iceland was mineralized to carbonate minerals in less than two years. This method could be used at many continental sites and in the off-shore basaltic ocean floor.

Martin Stute from the Lamont-Doherty Earth Observatory & Barnard College will be presenting on this topic in an exclusive seminar at Adelaide’s Flinders University.

Martin Stute is a Professor of Environmental Science at Barnard College, Co-chair of the Environmental Science Department, faculty member of Columbia’s Department of Earth & Environmental Science and Adj. Senior Research Scientist at the Lamont-Doherty Earth Observatory, Columbia University. He is an isotope hydrologist using environmental tracers to study the dynamics of aqueous systems. His research focuses on the reconstruction of past climate conditions from groundwater, global water resources issues, in particular related to Arsenic, dating of groundwater on all time scales, and the interface of water and energy including gas production by hydraulic fracturing  and CO2 sequestration. He currently teaches classes in Hydrology, Environmental Data Analysis, a client based workshop in Sustainable Development, and the joint Columbia/Barnard Environmental Science Senior Research Seminar.
