Patent number: 11867096Abstract: An energy storage system converts variable renewable electricity (VRE) to continuous heat at over 1000° C. Intermittent electrical energy heats a solid medium. Heat from the solid medium is delivered continuously on demand. An array of bricks incorporating internal radiation cavities is directly heated by thermal radiation. The cavities facilitate rapid, uniform heating via reradiation. Heat delivery via flowing gas establishes a thermocline which maintains high outlet temperature throughout discharge. Gas flows through structured pathways within the array, delivering heat which may be used for processes including calcination, hydrogen electrolysis, steam generation, and thermal power generation and cogeneration. Groups of thermal storage arrays may be controlled and operated at high temperatures without thermal runaway via deep-discharge sequencing. Forecast-based control enables continuous, year-round heat supply using current and advance information of weather and VRE availability.Type: GrantFiled: February 20, 2023Date of Patent: January 9, 2024Assignee: Rondo Energy, Inc.Inventors: John Setel O'Donnell, Peter Emery von Behrens, Chiaki Treynor, Jeremy Quentin Keller, Matthieu Jonemann, Robert Ratz, Yusef Desjardins Ferhani
