1. A system comprising:
a thermochemical energy storage module cyclically operable in a discharging cycle and in a charging cycle, the thermochemical energy storage module having a chamber in fluid communication with a first chamber port and a second chamber port;
in the discharging cycle, a gas mover fluidly coupled to the first chamber port to supply into the chamber a flow of gas containing volatile organic compounds having a first concentration, the volatile organic compounds being subjected to destructive thermal oxidation in response to thermal energy discharged by the thermochemical energy storage module so that discharge gas having a second concentration of the volatile organic compounds exits from the chamber by way of the second chamber port, wherein the second concentration is less than the first concentration;
a flow meter and a flow valve in fluid communication with the chamber; and
a controller coupled to the flow meter and to the flow valve to control a rate of the flow of the gas containing the volatile organic compounds based on a desired residence time for the flow of the gas.
