Focus of the funding initiative

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.

Salthydrates 14.3.2016

Cooling of buildings using new salthydrates

In the project PC-Cools_V two new phase change materials (PCM) on a salthydrate basis with a narrow melting range around 21°C and around 15°C are developed. The latter was intended for the implementation in central cold storages whereas the PCM melting at 21°C was designed for a decentral, room integrated storage application, especially cooling ceilings. ... more

Industrial waste heat utilisation 12.9.2017

Foundry using waste heat of the furnace

In energy-intensive industries, e.g. foundry industry or cement industry, the use of waste heat for example as process or space heating energy reduces the consumption of primary energy.  In the Project “IAST” researchers are testing an energy storage system for discontinuous industrial waste heat of a furnace at a foundry. The implementation and commissioning is expected to start at the end of 2014. ... more

Thermochemical solid heat accumulators 1.2.2016

Heat storage in smallest volume

Thermochemical heat storage can achieve low cost because of its higher specific energy density as compared with conventional heat storage materials. However, the thermal conductivity of the material is limited. Therefore, scientists at the Fraunhofer UMSICHT developed new thermochemical storage materials. The researchers intend to increase the thermal conductivity of solids, specifically through the addition of special additives. ... more

PCM storage 12.4.2017

Cheaper slurries for cooling processes

In order to reduce the cost of PCM storages, scientists develop new slurries and materials for cold storages. The aim of the project KOLAN is to develop an emulsion with a very high heat capacity. At a temperature difference of 6 Kelvin it should store about four times more heat than water. ... more
