CBE Seminar: “Creating a New Circular Carbon Economy via Carbon Capture, Utilization and Storage” (Alissa Park, UCLA)

Abstract:

To meet the ever-increasing global energy demands while addressing climate change, the development of carbon capture, utilization and storage (CCUS) technologies is one of the critical needs. In particular, there have been significant efforts to develop innovative CO 2 capture materials and CO 2 conversion technologies to create a new circular carbon economy based on renewable energy. The next-generation CO 2 capture materials, which are often water-free or water-lean, have unique structural and chemical properties that allow their applications in a wide range of reactive separation systems. Nanoparticle Organic Hybrid Materials (NOHMs) are organic-inorganic hybrids that consist of a hard nanoparticle core functionalized with a molecular organic corona that possesses a high degree of chemical and physical tunability. It has recently been discovered that NOHMs have interesting electrolyte properties that allow the CO 2 capture to be pulled by the in-situ CO 2 conversion reactions. The development of these unique nanoscale hybrid materials will not only advance CO 2 capture materials design but also introduce unique research opportunities in various sustainable energy and environmental fields. This seminar will discuss the challenges and opportunities of different CO 2 capture and conversion pathways including Negative Emission Technologies (e.g., Direct Air Capture) that can allow the development of circular carbon and hydrogen economy using renewable energy.
