摘要： An energy collection apparatus includes an upper body and a lower body. The upper body has a first storage compartment, and is arranged to connect to an external energy generator. The lower body downwardly extends from the upper body, and has a second storage compartment. The energy collection apparatus is securely supported in a deep sea level above seabed so that when sea water enters the first storage compartment and the second storage compartment, geothermal energy and pressure difference between the sea water in the first storage compartment and the second storage compartment create upthrust steam at a top portion of the first storage compartment, the upthrust steam being guided to reach the external energy generator for further use.

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 geothermal installation for collecting heat for the generation of electricity is provided. The installation includes a fluid transport system comprising at least one fluid injection bore extending from a thermoelectric generator located at or near the Earth's surface to a depth below the Earth's surface sufficient such that energy collected can produce electricity. In particular, a depth of at least 500 m, preferably at least 1500 m, and more preferably at least 3000 m is sufficient to see benefits. The fluid injection bore is connected at the said depth, respectively to a plurality of micro-tunnels which extend outwardly substantially horizontally or diagonally downwardly from a horizontal plane passing through the said depth, preferably interconnected in at least one array. The micro-tunnels in turn are connected with fluid return bores which return a heat transfer fluid to the thermoelectric generator. The fluid transport system is adapted for the flow therethrough to and from the thermoelectric generator of the heat transfer fluid.

摘要： Methods and systems for producing thermal or electrical power from geothermal wells. Power is produced from a working fluid circulating in a closed loop within a geothermal well. Geothermal steam or brine at depth transfers heat at higher temperature than at the surface to the working fluid. The working fluid is then used to produce power directly or indirectly. The geothermal production fluid may be stimulated through use of gas lifting or submersible pumps to assist in bringing such fluids to the surface or through the use blockers to encourage the downhole steam advection and brine recirculation through the resource in a connective loop. The working fluid may be compatible with existing direct heat or power generation equipment; i.e., water for flash plants or hydrocarbons/refrigerants for binary plants.

摘要： A process for generating power from a warm saline steam (1) obtained from geothermal sources. The process involves extracting a warm saline stream (1) from an underground geothermal formation (2), reducing the temperature of the saline stream (1) by passing the stream through a thermal power unit (5) in which thermal energy present in the stream is extracted. The process also involves converting latent osmotic energy present in the stream into electricity by passing the stream through an osmotic power unit (7) comprising a semi-permeable membrane (8). The output stream (13) derived from passage through the osmotic power unit is injected into a second, different underground formation.

摘要： A heat pump includes a first chamber, a second chamber fluidly coupled with the first chamber, a first and a second spray devices. The first and second chambers contain working fluid flowable between the first and second chambers via a flow passage between the first and second chambers, and a first and a second space above a portion of the working fluid that is within the first and second chambers. First spray device is coupled with the first chamber to heat or cool the first space in the first chamber. Second spray device is coupled with the second chamber to heat or cool the second space in the second chamber. At least one of the heating and cooling of the first space may cause at least one of a compression or expansion of the second space, which may drive a power-extraction unit coupled with the second chamber.

摘要： The present disclosure relates to a system for storing and time shifting at least one of excess electrical power from an electrical power grid, excess electrical power from the power plant itself, or heat from a heat generating source, in the form of pressure and heat, for future use in assisting with a production of electricity. An oxy-combustion furnace is powered by a combustible fuel source, plus excess electricity, during a charge operation to heat a reservoir system containing a quantity of a thermal storage medium. During a discharge operation, a discharge subsystem has a heat exchanger which receives heated CO2 from the reservoir system and uses this to heat a quantity of high-pressure, supercritical CO2 (sCO2) to form very-high-temperature, high-pressure sCO2 at a first output thereof. The very-high-temperature, high-pressure sCO2 is used to drive a Brayton-cycle turbine, which generates electricity at a first output thereof for transmission to a power grid. The Brayton-cycle turbine also outputs a quantity of sCO2 which is reduced in temperature and pressure to a heat recuperator subsystem. The heat recuperator subsystem circulates the sCO2 and re-heats and re-pressurizes the sCO2 before feeding it back to the heat exchanger to be even further reheated, and then output to the Brayton-cycle turbine as a new quantity of very-high-temperature, high-pressure sCO2, to assist in powering the Brayton-cycle turbine.
