摘要： The present disclosure relates to techniques for extracting heat energy from geothermal briny fluid. A briny fluid can be extracted from a geothermal production well and delivered to a heat exchanger. The heat exchanger can receive the briny fluid and transfer heat energy from the briny fluid to a molten salt. The molten salt can be pumped to a molten salt storage tank that can serve as energy storage. The briny fluid can be returned to a geothermal source via the production well. The briny fluid can remain in a closed-loop system, apart from the molten salt, from extraction through return to the geothermal production well.

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： 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 techniques may be used for incorporating direct air carbon dioxide capture capabilities into a working fluid condensing process of a geothermal power plant. An example technique may include causing, using fans, air to flow across condenser coils of a condensing unit, through which power cycle working fluid is circulated, and through a direct air capture (DAC) filtration component, which separates carbon from the air, capturing heat from a geothermal working fluid, and using the heat as thermal energy input to the DAC filtration component or using electrical energy generated from the geothermal power plant as electrical energy input to power the condensing unit and the DAC filtration component. The example technique may include gathering the carbon separated from the air to be injected into a geothermal reservoir or repurposed for another industrial process.

摘要： A geothermal system includes an outer vessel having a sidewall that is in contact with surrounding ground material. A geothermal pile is disposed within an interior volume of the outer vessel, wherein a first heat conducting liquid at least partially fills a space between an inner surface of the sidewall of the outer vessel and an outer surface of the geothermal pile when in an installed condition. A conduit disposed within an interior space of the geothermal pile conducts a second heat conducting liquid along a flow path within the geothermal pile toward a bottom end thereof and then back to an outlet at a top end thereof. During operation, heat is transferred from the surrounding ground to the second heat conducting liquid via the first heat conducting liquid within the space between the inner surface of the sidewall of the outer vessel and the outer surface of the geothermal pile.

摘要： Systems and generating power in an organic Rankine cycle (ORC) operation to supply electrical power. In embodiments, an inlet temperature of a flow of gas from a source to an ORC unit may be determined. The source may connect to a main pipeline. The main pipeline may connect to a supply pipeline. The supply pipeline may connect to the ORC unit thereby to allow gas to flow from the source to the ORC unit. Heat from the flow of gas may cause the ORC unit to generate electrical power. The outlet temperature of the flow of the gas from the ORC unit to a return pipe may be determined. A bypass valve, positioned on a bypass pipeline connecting the supply pipeline to the return pipeline, may be adjusted to a position sufficient to maintain temperature of the flow of gas above a threshold based on the inlet and outlet temperature.

摘要： A system and method of harvesting geothermal energy in a subterranean formation includes providing an injection wellbore that extends into the subterranean formation, positioning a plurality of selectively opening sleeves in the injection wellbore spaced apart the subterranean formation, providing at least one producing wellbore that extends into the subterranean formation in a predetermined location proximate to the injection wellbore, and fracturing the subterranean formation in a plurality of locations proximate to the plurality of selectively opening sleeves to enhance a fluid pathway between the injection wellbore and the at least one producing wellbore. Fluid is injected down the injection wellbore at a first temperature, and the fluid is produced from the at least one producing wellbore at a second temperature higher than said first temperature.

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： A method of generating electricity from geothermal energy utilizing an in situ closed loop heat exchanger deep within the earth using a recirculating heat transfer fluid to power an in situ modular turbine and generator system within a vertical, large bore, deep, tunnel shaft. The shaft length and diameter are dependent on the shaft temperature and sustaining heat flux. The method further includes methods of deep shaft boring and excavating, liner placement and sealing, shaft transport systems, shaft Heating, Ventilation, and Air Conditioning, and operations and maintenance provisions. The method has few global location restrictions, maximizes thermal efficiency as to make power generation practical, has a small site surface footprint, does not interact with the environment, is sustainable, uses renewable energy, and is a zero release carbon and hazardous substance emitter.
