SYSTEM AND METHOD FOR ACHIEVING GREEN, LARGE-SCALE, LONG-DURATION ENERGY STORAGE BY ELECTRICALLY HEATING CONFINED UNDERGROUND AQUIFER

Resumen de: WO2026200833A1

The present invention provides a system and method for achieving green, large-scale, long-duration energy storage by electrically heating a confined underground aquifer. The system uses underground aquifers confined by lithological formations, faults, or hydrocarbon-bearing formations such as oil- or coal-bearing formations as a heat storage medium, heats the aquifers by means of energy sources such as electrical energy, new energy, thermal energy or nuclear energy, and stores the thermal energy underground for a long period of time. When needed, the thermal energy and steam kinetic energy are converted into electrical energy or other forms of energy for output via a heat exchange system. The present invention has the advantages of large-scale energy storage, high efficiency and stability, environmental friendliness, and low cost, is suitable for various geographical conditions, and has broad application prospects.

GEOTHERMAL AND GEOPRESSURE RECOVERY SYSTEMS

Resumen de: US20260298213A1

A geothermal power system includes a pressure exchanger fluidically coupled to a heat exchanger. A first fluid enters the pressure exchanger at a first inlet, and flows in a first fluid path to a first outlet. The first fluid flows from the first outlet to the heat exchanger, where the first fluid heats a second fluid. The first fluid flows from the heat exchanger to a second inlet of the pressure exchanger. The first fluid flows in a second fluid path through the pressure exchanger to a second outlet. A pressure of the first fluid reduces as the first fluid transits through the pressure exchanger along the first fluid path. A pressure of the first fluid increases as the first fluid transits through the pressure exchanger along the second fluid path. The first fluid flows from the second outlet to a turbine which drives a generator.

Resumen de: WO2026203884A1

The present invention enables the effects of scale prevention and suppression in a geothermal power plant to be evaluated more rapidly. Provided is a method for evaluating the effects of preventing and suppressing scale adhesion in a geothermal power plant (100), the effects of preventing and suppressing scale adhesion being evaluated using a scale sensor device (120) that detects the degree of scale adhesion to the surface of a sensing unit by immersing the sensing unit, which is formed by exposing the core of an optical fiber in one or more locations, in a geothermal fluid produced from a production well (101) of the geothermal power plant. The scale sensor detects the degree of adhesion of scale at the production well (101) and an injection well (102) of the geothermal power plant and at any location therebetween, and detects the degree of adhesion of scale at any location after, for example, adding a chemical agent for preventing and suppressing the formation of scale into the geothermal fluid, or after changing the production method.
