Advanced ceramic materials with tailored properties are at the core of established and emerging energy technologies. First, ceramic materials possess outstanding thermomechanical properties combined with a high chemical stability which makes them irreplaceable for high-temperature applications as in gas turbines. Second, ceramic materials can also have high ionic and/or electronic conductivity with some catalytic activity. By adjusting both composition and microstructure, they are used in solid oxide fuel and electrolysis cells, membranes for oxygen and hydrogen transport as well as lithium/sodium solid-state batteries. New opportunities for materials design, the importance of processing and material integration into devices as well as the need for long-term testing under realistic conditions are highlighted in the present talk.
