Storing heat

In the various research networks, researchers are working on improving the components and structure of known technologies, for example, using new and less costly materials. One particular focus is on latent heat storage and sorption storage systems. The main application areas are storage for conventional and solar thermal power plants, for current-regulated CHP plants, seasonal storage for buildings, and storage facilities that simplify the management of heating networks.

Organic PCM 5.9.2016

Phase change material is crystallised

With micro-encapsulated or emulsified organic phase change materials, the solidification temperature is frequently below the melt temperature. This so-called undercooling is a hindrance for many applications. By means of systematic investigations, the researchers achieved a fundamental understanding of the physical principles. Based on the experimental findings, models developed that make it possible to forecast the crystallisation properties. ... more

Thermochemical storage 21.4.2016

Metal hydrides store faster with graphite

Many metal alloys can reversibly bind large amounts of hydrogen, forming metal hydrides. The chemical reaction releases large amounts of heat. Metal hydrides are therefore suitable not only for hydrogen storage but also as thermochemical heat storage. Metal hydride storages achieve extremely high charging and discharging performances by a combination of metal hydrides with thermally conductive graphite in a composite material. ... more
