摘要： The present disclosure relates to a system for storing and time-shifting at least one of power from a power grid, excess electrical power, renewable power, or heat for future use in assisting with a production of an industrial product. The system may incorporate a reservoir subsystem containing a quantity of a thermal storage medium, and configured to be heated using at least one of a heat-generation system or a heat-transfer system. A heating subsystem may also be incorporated which is configured to heat the quantity of thermal storage medium during a charge phase of operation, and which includes at least one of a first furnace for heating the quantity of thermal storage medium during the charge phase of operation using at least one of excess electrical power or renewable power, or a second furnace for heating the thermal storage medium during the charge phase of operation using O2 and at least one other combustible component, to form one of a carbon-neutral or carbon-negative heat. A discharge subsystem transfers a first thermal product carrying at least one of carbon-neutral or carbon-negative heat created from at least one of the first or second furnaces, in the form of a heated gas, which is used to create a second thermal product in a subsequent heat-intensive industrial operation.

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.

摘要： The present disclosure relates to a method for storing excess energy from at least one energy producing source, as thermal energy, using an existing geologic formation. First and second storage zones formed in a geologic region may be used to store high temperature and medium high temperature brine. When excess energy is available from the energy producing source, a quantity of the medium high temperature brine is withdrawn and heated using the energy supplied by the energy source to form a first new quantity of high temperature brine, which is then injected back into the first storage zone. This forces a quantity of medium high temperature brine present in the first storage zone into the second storage zone, to maintain a desired quantity of high temperature brine in the first storage zone and a desired quantity of medium high temperature brine in the second storage zone.

摘要： A geo-energy production system and method is disclosed for extracting thermal energy from a reservoir formation, and for storing at least one of thermal waste heat or excess heat in a storage zone of the reservoir formation. The system may at least one compressed fluid injection well in communication with the storage zone for injecting an unheated, compressed working fluid into the storage zone. The system may also have at least one fluid injection well in communication with the storage zone for injecting a working fluid laden with thermal waste heat or excess heat, into the storage zone, the storage zone being located below a caprock layer of the reservoir formation and above a zone of native brine within the reservoir formation. The storage zone is at least partially circumscribed by a hot brine storage zone of the reservoir formation. The compressed working fluid further assists with a withdrawal of pressurized brine residing below and/or to the sides of the storage zone. At least one compressed CO2, N2, or air energy storage production well is used, which is in communication with the storage zone for removing compressed working fluid from the storage zone for use in power production.

摘要： The present disclosure relates to a system for storing and time-shifting at least one of electrical power, excess electrical power, or renewable electrical power, to create low-carbon heat for future use in assisting with a production of asphalt paving material. The system makes use of a first thermally insulated storage subsystem containing a quantity of an asphalt paving material manufacturing component, and a first furnace configured to heat the asphalt paving material manufacturing component using an available supplemental energy source. A second thermally insulated storage subsystem is used to store a quantity of asphalt binder, and a second furnace is used to heat the quantity of asphalt binder. An air blower is used to supply a quantity of air to the first furnace to assist in a heating during a heat-charge phase of operation of the system in which both the quantity of asphalt paving material manufacturing component and the quantity of asphalt binder are pre-heated.

摘要： A geo-energy production system and method is disclosed for extracting thermal energy from a reservoir formation. In one implementation the method may involve using a production well to extract brine from the reservoir formation. A plurality of working fluid injection (“WFI”) wells may be arranged in a vicinity of the production well to at least partially circumscribe the production well. A plurality of brine production (“BP”) wells may be arranged in a vicinity of the WFI wells to at least partially circumscribe the WFI wells. A working fluid may be injected into the WFI wells to augment a pressure in the reservoir formation, to thus drive a flow of the brine up through the production well and up through the BP wells, together with at least a portion of the injected working fluid. Methods are disclosed involving the use of parasitic-load time-shifting to (1) soak up excess power from an electricity grid, with the excess power being stored as pressure (bulk energy), and to (2) store excess solar thermal energy, allowing renewable energy sources to be available to dispatch power whenever demanded by the grid.

At least one of nitrogen (N2) and carbon dioxide (CO2) may be used to form a supplemental working fluid which may be injected into a supplemental working fluid injection well. The supplemental working fluid may be used to augment a pressure of the reservoir formation, to thus drive a flow of the brine out from the reservoir formation.
