Abstract (en)
[origin: EP3865804A1] A thermal energy storage (100) for a thermal energy storage plant comprising a hollow housing (110) a granular material (120) for storing heat housed in the hollow housing (110). At least a storage grate (20) retains the granular material (120) inside the hollow housing (110), the storage grate (20) extending between a first end (11) and a second end (12), the first end (11) being closer to the bottom side (114) than to the top side (113), the storage grate (20) including at least a first grate section (20a) including the first end (11) and a second grate section (20b) including the second end (12), each grate section (20a, 20b) of the storage grate (20) comprises at least a first plurality of struts (51, 41, 42), the struts (51, 41, 42) being configured and arranged in each grate section (20a, 20b) in such a way that the mechanical strength of the first grate section (20a) is higher than the mechanical strength of the second grate section (20b).
