Storage Technology

Three different technologies come into play when storing thermal energy. Sensible heat storage systems alter the temperature of their storage medium while charging or discharging. The heat transfer is perceptible (sensible). In latent heat storage systems, the temperature of the medium remains constant; during charging and discharging, it undergoes a phase change, usually between solid and liquid. Thermochemical storage systems utilise the heat transfer resulting from reversible chemical reactions or sorption processes.

Our work focuses on:

• In the field of sensible heat storage, we develop innovative storage containers and concepts as well as charging devices. We also work on novel, highly efficient insulation materials.
• For latent and sorptive heat and cold storage, we develop and improve individual storage materials and components and integrate thermal storage into complex energy systems.
• We investigate storage materials and systems for heating and cooling systems, efficient household appliances, industrial waste heat utilisation, and automotive applications.
