Disclosed herein are system, apparatus, article of manufacture, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for using a thin-bed hot sedimentary aquifer (HSA) in geothermal energy generation applications. An example embodiment operates by pumping, via an extraction well, heated water from an extraction depth of an HSA. The HSA is identified based on a permeability satisfying a threshold permeability range and could even have a thickness equal to or less than about 100 meters. The example embodiment further operates by extracting, via a power generation unit, heat from the heated water to generate power and transform the heated water into cooled water. Subsequently, the example embodiment operates by injecting, via an injection well, the cooled water at an injection depth of the HSA. A first portion of the extraction well and a second portion of the injection well are disposed within the HSA.

Disclosed herein are various embodiments of systems for drilling and operating a well which may have dual uses. The well may be drilled and operated as a geothermal well using a hybrid approach where a heat transfer fluid is injected into a hot rock formation but is not removed, and heat is extracted using a closed loop method. The geothermal well is then evaluated for use as a carbon dioxide sequestration well. In other embodiments, the well is drilled as a carbon dioxide sequestration well and then evaluated for its potential for generating geothermal energy using a hybrid approach where supercritical carbon dioxide is injected into a hot rock formation but is not removed, and heat is extracted using a closed loop method. Both horizontal and vertical wells are disclosed, in sedimentary rocks and in basement granite.

A system may provide for a plurality of modular power plants in operable communication with one another, each individual power plant being at least partially disposed within a new well or exhausted oil or gas well or conventional geothermal well or along the length of a well. Each modular power plant may be considered a node within the network and may include multiple means of interconnectivity such that temporary loss or failure of a single node does not interfere with the operability of the remaining modular power plants. The system may be constructed and arranged for a decentralized power grid for residential, commercial, or industrial applications including electric vehicle charging or the like.

The condenser includes a downward flow condensing cell having a first liquid distribution assembly a first heat exchange media disposed below the first liquid distribution assembly. The condenser also includes an upward steam flow cooling cell and a second liquid distribution assembly along with a second heat exchange media disposed below the second liquid distribution assembly.

Methods for thermalsiphoning supercritical CO.sub.2 within a geothermal formation includes providing a geothermal energy system that includes an underground hot rock reservoir, a production well, and an injection well that together form a fluid path suitable for circulating supercritical CO.sub.2. The supercritical CO.sub.2 flows by thermosiphoning. Thermosiphoning is maximized by maintaining a pressure between 1400-4000 psia, an injection temperature in a range from 50-200 C and a production temperature in a range from 150-600 where injection temperature and the production temperature differ by at least 50° C.

Methods for constructing and a building kit for use thereof are disclosed. The building kit includes a plurality of posts configured for embedding within square apertures of a foundation, wherein the posts have a cross-shaped cross-sectional shape, a plurality of cross-shaped cross-sectional shaped elongated members, a plurality of roof panels, wherein the roof panels include solar cells, and a plurality of wall panels having conforming shape to the cross-shaped cross-sectional shaped elongated members.

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.
