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.

Heat storage system in a mine 4.7.2017

Storing heat in mines

What happens to mines that are no longer in use? Could they be used to store heat? Researchers at the International Geothermal Centre are hoping to find out whether mines could be put to this use and are conducting tests in the former Prosper-Haniel hard-coal mine in the Ruhr region to investigate whether it is suitable for heat storage. .

Industrial waste heat utilisation 12.4.2017

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

Absorption-storage system 12.4.2017

Drying with open sorption processes

A junior research group investigated heat and material transfer to an aqueous solution of lithium chloride. Such salt solutions can be used for air conditioning in buildings or waste heat. At the same time it serves as an energy storage. In addition to the salt solutions young researchers testing and synthesizing new sorbents. Also system simulations for building heating and air conditioning are planned in addition to drying applications. ... more

Sorption heat storage 12.4.2017

Sorptive heat storage using activated carbon

Activated carbon can be produced from a large variety of carbonaceous source materials. Different methods have also been established for the process steps of carbonization and activation for use in commercial applications. In the project HyAcitv researchers optimize activated carbons and in a further step, molded articles are produced for use in open sorption systems. The application of these moldings is demonstrated in a laboratory storage system. .

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
