Abstract: The establishment of a technical carbon cycle to address climate change highlights the urgent need for renewable syngas production, driving investigation into solar-thermic carbon dioxide decomposition as a promising solution. This process, operating above 1000°C, yields carbon monoxide crucial for syngas generation, along with excess oxygen that requires removal. Oxygen transport membranes offer a potential solution. However, their viability hinges on the use of mixed ionic electronic conductors capable of withstanding extreme temperatures over prolonged periods. This presentation delves into the critical aspect of material selection for oxygen transport membranes, offering insights into current advancements and methodologies for evaluating feasibility.Specifically, we address challenges inherent in ceria/zirconia and calcium titanate-based materials, emphasizing their long-term thermal, mechanical, and chemical stability. These properties are intricately linked to ionic conductivity and non-stoichiometry, crucial factors determining the success of oxygen transport membrane technology. Through a thorough examination of these challenges, we aim to enhance our understanding of material requirements and contribute to the development of more resilient and efficient solutions for renewable syngas production.
