Abstract: An energy storage system (TES) 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. Heat delivery via flowing gas establishes a thermocline which maintains high outlet temperature throughout discharge. The delivered heat which may be used for processes including power generation and cogeneration. In one application, the energy storage system provides higher-temperature heat to a solid oxide electrolysis system to maintain in an electrolysis operating temperature range during operation and nonoperation, thereby increasing the efficiency of the temperature control.

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. High-voltage DC power conversion and distribution circuitry improves the efficiency of VRE power transfer into the system.

Abstract: A bottoming cycle power system includes a turbo-expander operable to rotate a turbo-crankshaft as a flow of exhaust gas from a combustion process passes through the turbo-expander. A turbo-compressor is operable to compress the flow of exhaust gas after the exhaust gas passes through the turbo-expander. An open cycle absorption chiller system includes an absorber section operable to receive the flow of exhaust gas from the turbo-expander and to mix the flow of exhaust gas with a first refrigerant solution within the absorber section. The first refrigerant solution is operable to absorb water from the exhaust gas as the exhaust gas passes through the first refrigerant solution. The absorber section is operable to route the flow of exhaust gas to the turbo-compressor after the flow of exhaust gas has passed through the first refrigerant solution.

Abstract: A bottoming cycle power system includes an expander disposed on a crankshaft. The expander being operable to receive a flow of exhaust gas from a combustion process and to rotate the crankshaft as the exhaust gas passes through. An absorption chiller system has a generator section having a first heat exchanger to receive the flow of exhaust gas from the expander and to remove heat from the exhaust gas after the exhaust gas has passed through the expander. An evaporator section has a second heat exchanger to receive the flow of exhaust gas from the generator section and to remove heat from the exhaust gas after the exhaust gas has passed through the generator section. A compressor is disposed on the crankshaft and connected to the flow of exhaust gas. The compressor is operable to compress the exhaust gas after the exhaust gas has passed through the second heat exchanger.

Abstract: A waste heat recovery apparatus includes a heat exchanger, an expander, a condenser, a first tank, a reflux portion, a first passage portion, and a second passage portion. The heat exchanger is configured to generate steam. The expander is configured to recover heat energy of the generated steam as power. The condenser is configured to condense the steam passing through the expander. An inlet portion of the condenser is arranged above an outlet portion of the expander. The first tank is configured to store the working fluid liquefied by the condenser. The reflux portion is configured to reflux the liquid-state working fluid in the first tank to the heat exchanger. The first passage portion connects the outlet portion of the expander and the inlet portion of the condenser to each other. The second passage portion connects the first passage portion and the first tank to each other.
