Project goals

• Development and provision of a thermoelectric modular system that can be adapted to a wide range of applications
• Thermoelectric generator (TEG) based on ceramic materials with optimum system integration for use in the high temperature range
• Increasing the efficiency and economy of the overall system by means of adapted heat transfer systems for the thermal management of the thermo-electrical individual components

Expected advantages of the ceramic TEG modular system with optimised heat exchangers compared to conventional, commercially available TEG modules

• Ceramic materials allow operation in the high-temperature range and therefore make it possible to tap previously unused industrial waste heat sources for direct conversion into electrical energy
• Cost-effective and less environmentally harmful use of materials
• Thermal optimisation of the entire system by means of adapted heat exchangers delivers maximum efficiency and the best possible yield
• A heat exchanger TEG composite system that can be adapted to various industrial processes provides a robust, reliable, noiseless and vibration-free energy supply unit for very small consumers
• Autonomous operation of essential or safety-relevant components of a technical plant
