Abstract: 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.

Abstract: 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.

Abstract: 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 When excess energy is available from the energy producing source, a quantity of the medium high temperature brine is withdrawn and heated using the energy supplied by the energy source to form a first new quantity of high temperature brine, which is then injected back into the first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.
