Current tonnage O₂ production by cryogenic process is expensive and energy intensive because it operates at very low temperature and at elevated pressures. Dense mixed oxygen ionic and electronic conducting (MIEC) ceramic membranes offer potential to separate O₂ from air with a significant reduction of O₂ production cost. In this presentation, the speaker will give an overview of the progress of his group in the area of ceramic membranes for oxygen separation including early fundamental studies, recent scaling up and future directions.
