Power generation system using a thermochemical energy storage system or a thermal energy storage system

A method of charging a thermochemical energy storage (TCES) device or a thermal energy storage (TES) device integrated with a power generation system comprising:

• receiving, by a power generation system, a charge signal, the power generation system comprising a controller and a thermochemical energy storage (TCES) device or a thermal energy storage (TES) device, the TCES device or the TES device being configured to convert an electrical input into thermal energy or thermochemical energy;
• initiating, by the controller, a charging mode for the TCES device or the TES device based at least in part on the charge signal, the charging mode being initiated causes the electrical input to pass directly through an energy storage material;
• and
• terminating, by the controller, the charging mode based at least in part on a threshold temperature being reached or according to another signal from the controller.

A power generation system, comprising:

• a thermochemical energy storage (TCES) device or a thermal energy storage (TES) device that is configured to increase the thermal energy storage capacity or the thermochemical energy storage capacity by passing an electrical current directly through an energy storage material, wherein the thermal energy storage capacity or the thermochemical energy storage capacity is used to generate a heated gas;
• a heat engine that is directly or indirectly actuated by the heated gas discharging the TCES device or the TES device;
• a controller that is configured to operate the TCES device or the TES device in a charging mode or a discharging mode based at least in part on a signal;
• and
• the controller being configured to initiate the charging mode or the discharging mode based at least in part on identifying a power parameter from the signal, the charging mode instructing the TCES device or TES device to activate a transfer of heat from the energy storage material to the heated gas, the discharging mode instructing the TCES device or the TES device to discharge the heated gas.
