The evaluation panel of SCCER has emphasized the importance of the integration of thermal energy storage in the Swiss industry. Latent heat storage technologies can offer more compact thermal storage at a constant temperature level, in comparison to conventional, sensible thermal storage technologies. The focus of this project is the development of latent heat storage solutions for the Swiss industry based on the Phase Change Slurry (PCS) concept. Such systems promise higher energy densities both as refrigerants and as storage media while presenting much better heat transfer characteristics than conventional latent heat storage technologies. This technology is expected to deliver high thermal power and high temperature stability in a compact design that can operate with conventional components.
