Abstract: Carbon Capture Utilization and Storage (CCUS) is an important strategy in order to mitigate greenhouse gas emissions enabling a circular economy. Since CO2 emissions typically occur at high temperature processes, ceramic gas separation membranes can provide the necessary separation and purification steps, which are key aspects in CCUS. The presentation introduces different types of ceramic membranes able to separate CO2, O2, H2 or other relevant gases from gas mixtures such as flue gases or synthesis gas. In particular membrane reactors are a promising option because of its energy efficiency enabling the combination of chemical reactions and gas separation (process intensification) [1]. The working principles are ionic transport (CO32-, O2-, H+) or molecular sieving in dense or porous membranes, respectively. State-of-the-art processing of membrane components as well as potential applications towards CCUS are described. To reach a high performance of the membrane systems thin film membranes, active surface layers and thermochemical and -mechanical stable supports with designed porosity are required. The production and characterization of membrane structures is explained using the example of sequentially tape cast and laminated supported membranes. References[1] W. Deibert, M.E. Ivanova, S.
