摘要： Systems and methods for generating electrical power in an organic Rankine cycle (ORC) operation include one or more heat exchangers incorporated into mobile heat generation units, and which will receive a heated fluid flow from one or more heat sources, and transfer heat therefrom to a working fluid that is circulated through an ORC unit for generation of power. In embodiments, the mobile heat generation units comprise pre-packaged modules with one or more heat exchangers connected to a pump of a recirculation system, including an array of piping, such that each mobile heat generation unit can be transported to the site and installed as a substantially stand-alone module or heat generation assembly.

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： 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.

摘要： Embodiments of systems and methods for generating power in the vicinity of a drilling rig are disclosed. During a drilling operation, heat generated by drilling fluid flowing from a borehole, exhaust from an engine, and/or fluid from an engine's water (or other fluid) jacket, for example, may be utilized by corresponding heat exchangers to facilitate heat transfer to a working fluid. The heated working fluid may cause an ORC unit to generate electrical power.

摘要： A method of operating a thermal energy storage system comprises operating a pump to circulate a heat transfer fluid from cold storage through a heating system to hot storage, supplying electric power from an electric power grid external to the thermal energy storage system to power an electric heater in the heating system that heats the heat transfer fluid as it circulates through the heating system to hot storage, regulating a flow rate of the heat transfer fluid through the heating system so that the heat transfer fluid enters hot storage at a specified temperature, and regulating the supplying of electric power from the electric power grid to the electric heater to balance supply of and demand for power on the electric power grid and maintain a frequency, a voltage, or a frequency and a voltage of electric power on the electric power grid at specified values.

摘要： In a method of hybrid power generation in an environment with a gas pressure below the earth's atmospheric pressure, liquid water is extracted from a subsurface water ice deposit by pumping superheated-supercritical fluid heated by a heater through an extraction well into the subsurface water ice deposit in order to form a liquid water reservoir. Liquid water is pumped from the liquid water reservoir through the extraction well to the buffer tank. The liquid water is pumped from the buffer tank into a high pressure feeder system (HPFS) and a low pressure feeder system (LPFS), which are each also heated by the heater. The HPFS outputs supercritical water and the LPFS outputs flash steam into a combined injector and the mixture is injected into a turbine at near environmental pressure. This mixture explosively expands into superheated steam and passes through the turbine, powering an electrical generator.

摘要： Plastic-powered power generator. In an embodiment, the plastic-powered power generator comprises a primary reactor with an air-fuel distribution assembly configured to supply fluidized polymer, air, and oxidizer to a primary reactor chamber, and an ignition system configured to ignite a mixture of the fluidized polymer, air, and oxidizer. The primary reactor chamber extends into a secondary reactor, to, when ignited, heat air flowing through the secondary reactor from a blower to a heat exchanger. The heated air flow converts fluid, in a coil within the heat exchanger, into steam, which can drive a turbine to generate electrical power.
