Carbon Capture and Reliable Storage

  • Associate Professor, Chemical and Biological Engineering Department, Colorado School of Mines

The scale by which CO2 must be mitigated worldwide dwarfs the existing chemical industry, making utilization of CO2 as a chemical feedstock a minor component of the portfolio of mitigation options. Carbon capture and storage is one strategy that could potentially mitigate gigatons of CO2 emissions per year, provided geological storage of CO2 is feasible. The scale and energy requirements associated with CO2 separation processes will be presented. Strategies based upon catalytic membrane separation processes in particular, will be of focus. Regeneration of CO2 is known to be a significant component of sorption-based separation processes and is absent when using membrane technologies. This work involves the adsorption, dissociation, and sub-surface diffusion of N2 in Group V-based metals, including vanadium, niobium, and their alloys with ruthenium. Experimental N2 flux measurements have been carried out to validate the theoretical predictions. Application of separation of N2 to use as a feedstock for ammonia synthesis will be presented.

Jennifer Wilcox is an associate professor in the Chemical and Biological Engineering Department, Colorado School of Mines. Her PhD is in Chemical Engineering, from the University of Arizona (2004), and her BA in Mathematics is from Wellesley College (1998). She received an ARO Young Investigator Award (Membrane Design for Optimal Hydrogen Separation), an ACS PRF Young Investigator Award (Heterogeneous Kinetics of Mercury in Combustion Flue Gas), and an NSF CAREER Award (Arsenic and Selenium Speciation in Combustion Flue Gas). Within her research group, she focuses on trace metal and CO2 capture. Her research involves the coupling of theory to experiment to test newly designed materials for sorbent or catalytic potential. She has served on a number of committees including the National Academy of Sciences and the American Physical Society to assess CO2 capture methods and impacts on climate. She is the author of the first textbook on Carbon Capture, published in March 2012.
