Inventors include Van Der Wegen, Gerardus Johannes Leonardus; Verbist, Guy Lode Magda Maria; Kruijer, Alfred Arnold; Muehleisen, Natalie Nicole; and Filho, Fernando Frana De Mendona.
The application for the patent was published on June 26, 2026, under issue no. 26/2026.
Abstract: In accordance with one aspect of the present invention, there is provided a material for thermal energy storage comprising one or more metallic species selected from metals and/or metal alloys encapsulated in a structural host material, wherein the metallic species has a melting point in the range of from 300 to 900°C and wherein the structural host material comprises at least 90% by mass of a hardened inorganic binder comprising one or more of a hydraulic binder, an alkaline activated material and a phosphate binder. In accordance with another aspect, the invention provides a method of manufacturing said material for thermal energy storage, the method comprising the steps of: - providing a mixture of the metallic species in solid state, and dry unreacted binder capable of reacting with a specified liquid; - adding the specified liquid to the mixture thereby generating a paste of the binder containing the metallic species; - casting the paste in a desired shape; and - allowing the paste to harden, comprising reacting with the specified liquid, whereby the paste is transformed into a structural host material which encapsulated the metallic species. In accordance with still another aspect, there is provided a method of heating a process stream by electric power, comprising: - directly or indirectly electrically heating a quantity of the material for thermal energy storage; and - passing a process stream in direct or indirect heat exchange with the quantity of the material, thereby heating the process stream with heat from the quantity of material.
