A heat storage (100) for a thermal energy storage plant (10) comprises: a hollow housing (170) comprising an inlet (101) and an outlet (102), a granular material (160) for storing heat housed in the hollow housing (170) between the inlet (101) and the outlet (102), the hollow housing (170) defining a fluid passage for the circulation of a heat transporting fluid between the inlet (101) and the outlet (102) and through the granular material (160). The granular material (160) subject to the gravity force forms at least one free surface (161, 162) respectively facing the inlet (101) or the outlet (102) the at least one free surface (161, 162) including a border (A, B) in contact with the hollow housing (170) and being inclined with respect to the gravity direction, the respective inlet (101) or outlet (102) being with respect to the gravity direction at a higher level than a lowest point (A) of the at least one free surface (161, 162). 用于热能存储设备(10)的热存储装置(100)包括：中空壳体(170)，其包括入口(101)和出口(102)；用于存储热量的颗粒材料(160)，所述颗粒材
