<p>It is described a thermal energy storage and recovery device (400), which comprises (a) a heat exchanging arrangement having a first end (412a) and a second end (413a), wherein the heat exchanging arrangement (110) is configured for guiding a flow of a heat transfer fluid between the first end (412a) and the second end (413a), (b) a heat storage material which is thermally coupled to the heat exchanging arrangement in such a manner that along a physical extension of the heat exchanging arrangement a thermal interaction region is formed for thermally coupling the heat transfer fluid with the heat storage material, (c) a fluid terminal (415a), which is connected to the heat exchanging arrangement via a branch duct (415b) of the heat exchanging arrangement, wherein the branch duct (415b) is located between the first end (412a) and the second end (413a), and (d) a control device, which is coupled to the fluid terminal (415a) and which is configured such that a flow of fluid through the fluid terminal (415a) is controllable in such a manner that within the heat exchanging arrangement a spatial temperature profile along at least a portion of the thermal interaction region is adjustable. Further, there are described a method for adjusting a temperature profile along a heat exchanging arrangement of a thermal energy storage and recovery device (400) and a thermal energy storage and recovery system comprising such a thermal energy storage and recovery device (400).</p> |
