摘要： Methods and systems for generating power (and optionally heat) from a high value heat source using a plurality of circulating loops comprising a primary heat transfer loop, several power cycle loops and an intermediate heat transfer loop that transfers heat from the high-temperature heat transfer loop to the several power cycle loops. The intermediate heat transfer loop is arranged to eliminate to the extent practical the shell and tube heat exchangers especially those heat exchangers that have a very large pressure difference between the tube side and shell side, to eliminate shell and tube, plate type, double pipe and similar heat exchangers that transfer heat directly from the primary heat transfer loop to the several power cycle loops with very high differential pressures and to maximize the use of heat transfer coils similar in design as are used in a heat recovery steam generator commonly used to transfer heat from gas turbine flue gas to steam or other power cycle fluids as part of a combined cycle power plant.

摘要： A first turboexpander generator defines a portion of a first conduit flow passage. The first turboexpander generator is configured to decrease a temperature or pressure of a process stream flowing through the first turboexpander generator by generating electrical power from the process stream. A second turboexpander generator defines a portion of a second conduit flow passage. The second turboexpander generator is configured to decrease a temperature or pressure of a process stream flowing through the second turboexpander generator by generating electrical power from the process stream. The first and second conduit flow passages are arranged to carry fluid flow in parallel to one another. The first and the second turboexpander generator are substantially identical in critical dimensions and performance.

摘要： A technique increases the round-trip efficiency (“RTE”) of a pumped thermal energy storage system by changing the coefficient of performance (“COP”) and efficiency of the cycles by changing the temperature ratios of each, which is accomplished by using two separate low temperature reservoirs (“LTRs”) that are at different temperatures. More particularly, the disclosed technique accomplishes this by using a low-temperature thermal reservoir during the charging process that is at a higher temperature than the generating cycle's low-temperature thermal reservoir. The low-temperature thermal reservoirs are “decoupled” and “independently existing”, in that their temperature and utilization are independent of one another. In general, decoupled and independently existing reservoirs may also be different in their independent reservoir media, reservoir location, and heat exchangers.

摘要： A power plant comprises a steam system, a first electrolyzer, a heat storage system, and a heat exchanger configured to exchange thermal energy between the steam system, the first electrolyzer and the heat storage system. A method of operating an electrolyzer in a combined cycle power plant comprises operating a steam system to convert water to steam, operating an electrolyzer in a standby mode, the electrolyzer configured to convert water and electricity to hydrogen and oxygen when the electrolyzer is in an operating mode, circulating water from the steam system through a heat exchanger, circulating a first heat transfer medium between the electrolyzer and the heat exchanger, and circulating a second heat transfer medium between the heat exchanger and a thermal storage container.

摘要： A turbine engine assembly includes a core engine that generates an exhaust gas flow, a condenser where water is extracted from the exhaust gas flow, an evaporator where heat is input into the water that is extracted by the condenser into a first steam flow, a steam turbine where the first steam flow is expanded and cooled, and a superheater where additional heat is input into the first steam flow that is exhausted from the steam turbine to generate a second steam flow. The second steam flow is injected into a core flow path of the core engine.

摘要： Systems and methods for generating and a controller for controlling generation of geothermal power in an organic Rankine cycle (ORC) operation in the vicinity of a wellhead during hydrocarbon production to thereby supply electrical power to one or more of in-field operational equipment, a grid power structure, and an energy storage device. In an embodiment, during hydrocarbon production, a temperature of a flow of wellhead fluid from the wellhead or working fluid may be determined. If the temperature is above a vaporous phase change threshold of the working fluid, heat exchanger valves may be opened to divert flow of wellhead fluid to heat exchangers to facilitate heat transfer from the flow of wellhead fluid to working fluid through the heat exchangers, thereby to cause the working fluid to change from a liquid to vapor, the vapor to cause a generator to generate electrical power via rotation of an expander.

摘要： Integrated Energy Systems (IESs), such as for use in capturing atmospheric carbon dioxide, and associated devices and methods are described herein. A representative IES can include a power plant system having multiple modular nuclear reactors, a desalination plant, a brine processing plant, and a direct air capture plant. The nuclear reactors can generate electricity and/or steam for use by the desalination plant and the direct air capture plant. The desalination plant can use the electricity and/or steam to produce brine from seawater or brackish water. The brine processing plant can receive the brine from the desalination plant and process the brine to produce sodium hydroxide. The direct air capture plant can use the sodium hydroxide as a liquid sorbent in a direct air capture process to capture carbon dioxide from atmospheric air.
