NETL researchers highlighted the Lab’s robust research to develop effective membranes for post-combustion carbon dioxide (CO2) capture at the North American Membrane Society’s 28th Annual Meeting. The meeting, held May 11-15 in Pittsburgh, attracted the world’s top scientists pursuing groundbreaking membranes research. Workshops, plenary lectures, technical sessions and poster exhibits focused on this year’s theme, “Membrane Separations for Emerging Water, Energy and Health Applications.” For energy applications, membrane technologies use permeable or semi-permeable materials to selectively separate and transport CO2 from flue gases. The relative simplicity of membrane-based CO2 capture processes offers reduced capital and maintenance costs as compared to other separation technologies. NETL’s membranes research focuses on the development of low-cost, durable membranes with improved permeability and selectivity, thermal and physical stability, and tolerance to contaminants in combustion flue gas.
