In the joint project MoWiE (modular heat storage systems for the industrial use), a robust and efficient latent heat storage module for industry is being developed and tested in a waste-to-energy power plant together with the partners DLR-Institute of Engineering Thermodynamics, SIK Peitz, Progroup Power 1 GmbH and Knauf Interfer Aluminium.

The aim is to develop a modular high-temperature latent heat storage unit with a focus on scalability for flexible adaptation to various industrial processes as well as its construction and integration into an existing production process. The realization takes place in four phases: First, the existing production process is analyzed by Progroup and simulated as well as validated by the DLR-Institute of Low-Carbon Industrial Processes. Based on this, a storage module is predesigned by the DLR-Institute of Engineering Thermodynamics and designed in detail by SIK; in addition, surrogate models of the PCM storage system are developed as realistically as possible and suitably integrated into the virtual system simulation. The demonstration module is then built by SIK, integrated into the Progroup process and tested. As an associated partner, Knauf Interfer Aluminium designs and provides the integrated heat-transfer finned tubes. Finally, the results from real operation allow conclusions to be drawn about the performance stability of the system on the one hand and the adaptation to a multi-modular storage system on the other.
The result of the project is a cost- and energy-efficient design of innovative storage modules and a simulation-based methodology for optimized process integration.
