Air Liquide is developing a novel polyimide-based membrane material, PI-2, for application in their hybrid process that combines cold membrane operation with cryogenic separation to reduce the overall cost of capturing carbon dioxide (CO2) from flue gas. The focus of the project is to advance the high CO2 permeance PI-2 material to commercial-scale, 6-inch bundles for testing with actual flue gas in a 0.3-megawatt-electric (MWe) test unit at the National Carbon Capture Center (NCCC).
