Abstract: To produce power using the cold in a stored fluid in a cold condensed state (for example, LNG or liquid air), the fluid is initially pumped, heated, and expanded to generate a first amount of power and form initially expanded fluid, which is then re-condensed, re-pumped, re-heated, and re-expanded to generate a second amount of power, where the initially expanded fluid is re-condensed against the pumped fluid from the initial pumping. The technique can be used to store excess energy in the cold condensed fluid using excess energy generation capacity for subsequent recovery when energy is either deficient or otherwise more expense to generate.

Abstract: 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.
