TCM Storage System Prototype in Container for integration in a single familiy house

The picture is showing a TCM storage system with 3 moduels in combination with a heat pump system and 2 m³ buffer storage installed in a container as complete storage system. The container is shipped to a single familiy housein Warsaw and installed next to the house to store surplus of solar thermal energy from summer and provide space heating in winter

Overview Task 58 for Material and Component Development for Compact Thermal Storage Systems

The figur shows the overview and contents of the IEA SHC Task 58 for material and component development for compact heat storage. The task is divided into 4 subtasks dealing with the definition of boundary conditions, development of TCM and PCM materials, test methods and component design of compact heat storage systems.

The 4 large thermal energy storage technologies of IEA ES Task 39

Schematic presentation of the 4 large thermal energy storage technologies that are included in the IEA ES Task 39: Tank thermal energy storage (TTES), pit thermal energy storage (PTES), borehole thermal energy storage (BTES) and aquifer thermal energy storage (ATES).

IEA ES Task 39 experts at the Meldorf PTES under construction

The IEA ES Task 39 expert group in from of the pit thermal energy storage of Meldorf (DE) under construction.

Power to Heat

Example of a high-temperature heat storage in a food industry. Excess electricity is stored as heat and used in the production process at a later time.

Pit thermal energy storage in Dronninglund (DK)

The pit thermal energy storage of 60,000 m3 in Dronninglund, Denmark, stores heat coming from a solar thermal field and a heat pump.

Pit thermal energy storage in Aalborg

Interior of the 54.000 m3 tank thermal energy storage during the construction. It is one of four TTES serving as buffer storage for the power plant of Aalborg Forsyning in Denmark.
