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 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： 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.

摘要： 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 steam cracking furnace system for converting a hydrocarbon feedstock into cracked gas, thereby increasing the efficiency of the temperature control.

摘要： The present disclosure provides pumped heat energy storage systems that can be used to store and/or extract electrical energy. A pumped heat energy storage system of the present disclosure can store energy by operating as a heat pump, whereby net work input can be used to transfer heat from the cold side to the hot side. A working fluid of the system is capable of efficient heat exchange with heat storage fluids on a hot side of the system and on a cold side of the system. Such pumped energy storage systems can be beneficially integrated with steam plants to provided heating to the steam cycle.
