Towards Sustainable Energy: Carbon Capture, Utilization and Storage (CCUS) Ah-Hyung Alissa Park Thursday, May 1st; 1pm; Barus & Holley 168 Department of Earth and Environmental Engineering, Department of Chemical Engineering, and Lenfest Center for Sustainable Energy, Columbia University, New York, NY 10027 Lenfest Professor in Applied Climate Science and Associate Director of the Lenfest Center for Sustainable Energy, Phone: 212-854-8989 Fax: 212-854-7081 E-mail: Historically, the atmospheric concentration of CO2 fluctuated naturally on the timescales of ice ages. Concerns, however, stem from the recent dramatic increase in CO2 concentration, which coincides with global industrial development. This rise is mainly due to the high use of fossil fuels. In order to meet the ever-increasing global energy demands while stabilizing the CO2 level in the atmosphere, it is widely believed that current carbon emissions must be reduced by at least a factor of three. The containment of CO2 involves three steps: separation, transportation, and storage. Until now, these technologies have been developed independently of one another, which has resulted in complex and economically challenging large-scale designs. The future direction of carbon management technologies now focuses on the integration of CO2 capture and storage schemes as well as CO2 conversion/utilization. In this seminar, two novel carbon capture, utilization and storage (CCUS) technologies will be introduced. Nanoparticle Organic Hybrid Materials (NOHMs) are a new class of organic-inorganic hybrids that consist of a hard nanoparticle core functionalized with a molecular organic (e.g., polymeric) corona that possesses a high degree of chemical and physical tunability. NOHMs are non-volatile and stable over a very wide temperature range, which make them interesting materials for various energy and environmental applications. The second set of CO2 capture materials is derived from Mg- and Ca-bearing minerals and industrial wastes. The main advantage of carbon mineralization is that it is the most permanent and safe method of carbon storage, since the gaseous CO2 is fixed into a solid matrix of Mg-bearing minerals (e.g., serpentine) forming a thermodynamically stable solid product. These carbon sequestration technologies can be integrated into the existing or new energy conversion systems in order to improve their overall sustainability. Short Bio: Ah-Hyung (Alissa) Park is the Lenfest Professor in Applied Climate Science of Earth and Environmental Engineering & Chemical Engineering at Columbia University. She is also the Associate Director of the Lenfest Center for Sustainable Energy. Park received her Bachelors and Masters from the University of British Columbia, both in Chemical Engineering and joined Columbia University in the fall of 2007 after completing her Ph.D. in Chemical Engineering at the Ohio State University. Her research interests include carbon capture and storage, sustainable energy conversion systems, and particle technology. Park received a number of professional awards and honors including the NSF CAREER Award in 2009 and the James Lee Young Investigator Award in 2010. She is currently leading the NSF-funded Research Coordination Network on Carbon Capture, Utilization and Storage (
