US 2018/0003445 A1 · HIGH TEMPERATURE THERMAL ENERGY STORAGE, A METHOD OF BUILDING AND A METHOD OF OPERATING SAID STORAGE

Abstract

High temperature thermal energy storage, distinctive in that the storage comprises: a thermally insulated foundation, at least one self-supported cassette arranged on said foundation, which cassette is a self-supporting frame or structure containing a number of concrete thermal energy storage elements, some or all of said elements comprising embedded heat exchangers, a pipe system, the pipe system comprising an inlet and an outlet for thermal input to and output from the storage, respectively, and connections to said heat exchangers for circulating fluid through said heat exchangers for thermal energy input to or output from said thermal energy storage elements, and thermal insulation around and on top of the at least one self-supported cassette with concrete thermal storage elements. The invention also provides a method of building and methods of operating the storage.
