Fraunhofer Institute for Mechanics of Materials IWMInnovative materials for the energy transition: Optimization of perovskite anodes in solid oxide electrolysis cells
Research, validation, and implementation of power-to-X concepts
Completed research project
Project description
The aim of the project was to develop, demonstrate, and implement solutions that use renewable electrical energy to produce materials-based energy sources and chemical products for applications in the leading industrial markets of energy, transport/traffic, and chemicals in an economical, flexible, and socially responsive manner. Using an integrated transdisciplinary approach, the potential of different technology options was assessed, then obstacles to their implementation were identified. From the outset, the innovation process encompassed technological progress, social change, and economic potential. The technological fields of action included the essential key competencies of electrolysis, catalysis, and materials and process design. The project involved conducting a continuous sustainability assessment and evaluating the opportunities for system integration under the current and expected future social and regulatory conditions. Based on a systematic roadmapping process, successful developments over the entire 10-year period were consolidated and brought to technical realization for at least three new technologies.
The specific field of research was high-temperature co-electrolysis for synthesis gas production, which involved developing a deeper understanding of the catalysis processes with the aim of identifying potential for optimization. Co-electrolysis produces valuable synthesis gas from water and CO₂. This technology could play a key role in the energy transition by efficiently storing and utilizing surplus renewable energy.
Fraunhofer IWM subproject:
- Atomistic simulation for the optimization of perovskite materials as anodes in solid oxide electrolysis cells (SOECs)
- High-precision materials-based physics simulations for the investigation of point defects in the crystal lattice – a decisive factor for the catalytic activity of the electrodes
- Close cooperation with partners in experimental research to synthesize novel anode materials as well as to visualize and analyze atomically resolved structural information
- The results show promising ways to improve the performance of these materials in order to make SOECs more durable and efficient.
Transfer of project results to the following Fraunhofer IWM R&D services for companies:
The project results can be applied to materials optimization for solid oxide electrolysis cells (SOECs) by using the simulation methods developed for defect assessment and catalysis improvement. In addition, the findings can be implemented in service life prediction and hydrogen research, particularly for optimizing materials for high-temperature and power-to-X applications.
