Abstract: A geothermal plant, for extracting energy from a geothermal reservoir located below the ocean bottom, includes a floating platform; a riser that extends from a well drilled into the geothermal reservoir, to the floating platform; an electrical pump having a mechanical actuation part located in a bore of the riser, and an electronic part located outside the riser, wherein the electrical pump is configured to pump a geothermal liquid from the geothermal reservoir to the floating platform; and a power plant located on the floating platform and configured to use a steam produced by the geothermal liquid to generate electrical power. The electrical pump is placed at a depth of the riser where the geothermal liquid is in a single-phase.

Abstract: A heat-pipe type heat extraction integrated with combined cooling power and heating exploitation-utilization integrated geothermal system includes an underground heat pipe, a steam pump, a first absorption bed, a second absorption bed, a first condenser, an electronic expansion valve, an evaporator, a liquid storage tank, a balance valve, a steam turbine, an generator connected to the steam turbine, a second condenser, a heat utilization device connected to the second condenser, a pressurizing pump connected to the second condenser, and relevant linkage valve assemblies. The system controls a flow direction and a flow rate after heat pipe steam is extracted from the ground through the steam pump and the regulating valves on the refrigeration side and the power generation side, so as to select the refrigeration/electric heating single-mode heat utilization or adjust flow distribution during refrigeration/electric heating dual-mode combined use.

Abstract: A method for estimating a location on the ocean bottom for drilling a well for exploring a geothermal reservoir, includes receiving data sets indicative of the geothermal reservoir and ocean conditions above the geothermal reservoir, selecting plural factors represented in the data sets and indicative of the geothermal reservoir, associating each factor of the plural factors with one or more criterion that indicates a desirability of drilling the well at the location of the geothermal reservoir, assigning to each factor an individual score based on the one or more criterion, aggregating the individual scores into a single overall score, and selecting the location of the geothermal reservoir when the single overall score is larger than a given threshold.

Abstract: Provided are methods and systems for converting a passive cooling system into an active hydronic ground cooling system. In an aspect, an existing passive cooling device can be first discharged of working fluid. An existing pipe of the passive cooling system can then be cut to a predetermined height. A top portion of the existing pipe can be threaded and fitted with a cap base. Tubing can then be installed within the existing pipe. A cap can be attached to the cap base. The tubing can be attached to a chiller system and filled with coolant. Similar procedure can be applied to convert a thermopile or traditional pipe pile to into an active cooling system.

Abstract: A geothermal pile for harvesting electricity from a gradient of temperature between ambient air and an underground area is provided. The geothermal pile includes an elongated thermally-conductive body, a thermoelectric cell and an electrical output. The elongated thermally-conductive body has a first end and a second end opposite the first end. The second end is configured to be introduced, in use, into an underground area. The thermoelectric cell is provided at the first end so as to be exposed to ambient air when the second end is introduced into the underground area. The thermoelectric cell is in thermal contact with the second end of the elongated thermally-conductive body and is configured to generate electricity from a gradient of temperature between a first temperature of the ambient air and a second temperature of the underground area. The electrical output is electrically connected to the thermoelectric cell.

Abstract: A system for extracting geothermal heat energy: includes a geothermal well formed in surrounding crust material and extending from a well top part down to a depth where the surrounding crust material has elevated geothermal temperatures. The geothermal well includes a heat medium contained within geothermal well walls. The heat medium is heated at a well bottom part by heat extracted from the surrounding crust material, evaporating and rising to carry heat energy towards the well top part. A heat extractor, extracts heat energy from the heat medium at the well top part. At least one heat conductive path extends outwardly from the geothermal well into the crust material to conduct geothermal heat from the crust material surrounding the path towards the well bottom part.

Abstract: A ladder-structural gravity-assisted-heat-pipe geothermal energy recovery system without liquid-accumulation effect, comprises a ladder-structural gravity-assisted heat pipe, a condenser, and a liquid tank. The ladder-structural gravity-assisted heat pipe comprises a return pipe, an outer pipe and an inner pipe. The return pipe is provided in a space between the outer pipe and the inner pipe and communicated with the liquid tank, and the space between the outer pipe and the inner pipe is divided to form a ladder structure. A liquid working medium flows from the liquid tank through the return pipe into each section sequentially, absorbs heat from a high-temperature rock through a wall of the outer pipe, vaporizes into a gaseous working medium, gets into the inner pipe, and rises to the condenser to condense and flows to the liquid tank to circulate. Such design greatly improves the heat transfer efficiency in geothermal energy recovery using ultra-long heat pipes.
