It is described a thermal energy storage and recovery device (100, 200) comprising (a) a container (105) having a first fluid terminal (110, 210) for inserting a heat transfer medium into the interior of the container and a second fluid terminal (120, 220) for extracting the heat transfer medium from the interior of the container, (b) a heat storage material for receiving thermal energy from the heat transfer medium when the device is in a first operational mode and for releasing thermal energy to the heat transfer medium when the device is in a second operational mode, and (c) a plurality of enclosures (130) each being filled at least partially with a part of the heat storage material, wherein the enclosures are spatially arranged within the container in such a manner that a flow of the heat transfer medium is guidable between the first fluid terminal and the second fluid terminal and a direct thermal contact between the heat transfer medium and the enclosures is achievable as the heat transfer medium flows between the first fluid terminal and the second fluid terminal. Further, a thermal energy storage and recovery system being equipped with such a device is described. Furthermore, a method for storing thermal energy within such a device and a method for recovering thermal energy from such a device are described. |
