Improvement of heat exchange by means of metallized zeolites

The heating season in Germany has started again and in terms of a sustainable energy supply, concepts for an effective heat utilization are needed. In this context, thermal storage facilities, which are flexible in use and have high storage capacities, are moving into focus. Thermal storage systems based on zeolite materials offer great potential, but have so far suffered from a lack of efficient heat transfer between storage material and heat exchanger. In the framework of the ZeoMet project (FKZ 100346109) funded by the Saxon Ministry of Economic Affairs, Labour and Transport, the Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP has found a new way to coat zeolite granulate, so that an efficient heat transfer is made possible.

Currently, the scientists of the Fraunhofer FEP are engaged in investigations on the scale-up when using different granulate grain sizes and properties in order to be able to react to specific requirements of different storage applications. Interested companies are invited to contact the responsible scientists. They will gladly explain the possibilities and potentials of the technology and get into deeper discussions in order to ensure that future work is both practice-oriented and relevant to industry.
