Ceramic-based oxygen transport membranes for clean and efficient energy generation

By Sapna Gupta

Worldwide energy use is growing tremendously as developing economies progress, yet coal and natural gas remain important in the required energy demand and production. Gasification and oxy-combustion are two processes that can allow higher-efficiency power production with a carbon dioxide-enriched byproduct stream convenient for carbon capture. However, both processes use large amounts of oxygen, which predominantly comes from cryogenic air separation plants.
