Systems for generating geothermal power in an organic Rankine cycle operation during hydrocarbon production based on wellhead fluid temperature

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.

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.

HEATING AND COOLING SYSTEM POWERED BY RENEWABLE ENERGY AND ASSISTED BY GEOTHERMAL ENERGY

A heating and cooling system powered by renewable energy and assisted with geothermal energy includes a solar cycling unit, a supercritical carbon dioxide (S—CO.sub.2) unit, and a refrigerant cycling unit. Solar energy obtained at the solar cycling unit may be used to power the S—CO.sub.2 cycling unit. To do so, the solar cycling unit utilizes a solar collector, a thermal energy storage, and a heat exchanger along with a first working fluid which is preferably molten salt or Therminol. Next, the energy generated at the S—CO.sub.2 cycling unit, which preferably circulates S—CO.sub.2 as a second working fluid, may be used to operate the refrigerant cycling unit. In the refrigerant cycling unit, Tetrafluroethene is preferably used as the third working fluid to produce required cooling effects. Additionally, geothermal heat exchangers may be integrated into the system for use during varying weather conditions.

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 CO.sub.2 from the reservoir system and uses this to heat a quantity of high-pressure, supercritical CO.sub.2 (sCO.sub.2) to form very-high-temperature, high-pressure sCO.sub.2 at a first output thereof. The very-high-temperature, high-pressure sCO.sub.2 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 sCO.sub.2 which is reduced in temperature and pressure to a heat recuperator subsystem. The heat recuperator subsystem circulates the sCO.sub.2 and re-heats and re-pressurizes the sCO.sub.2 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 sCO.sub.2, to assist in powering the Brayton-cycle turbine.

A system for the generation of mechanical or electrical energy from heat energy, where increasing a height or pressure in a liquid chamber of the system containing a liquid increases an efficiency of the system up to a hundred percent or increases such efficiency until a critical temperature or pressure of the vapor (gas) is reached at the bottom of liquid chamber or in the boiler of the system depending upon the increment in height, pressure and the type of liquid used in the system. An increase in height of the system for such increased efficiency can be adjusted to a smaller height by maintaining a series of liquid and gas chambers where the vapor flows through the series of chambers or by adding pressure valves. The heat energy from high to low temperature sources can be convened to mechanical and electrical energy.
