A closed-cycle thermal energy storage system includes a thermochemical reactor [] containing a solid thermochemical material, a heat exchanger [], a fan [] for creating forced convection of an air/water mixture circulating around the closed cycle, an evaporator/condenser [], and a pressure control system that includes a pressure sensor [], a controller [], and a pump []. The pressure control system actively controls the pressure of the air/water mixture to produce a desired temperature difference across the thermochemical reactor []. The adjustable pressure control system controls the pressure of the air/water mixture to a first pressure (e.g., between 10 mbar and 1 bar) during a hydration phase and a second pressure (e.g., between 1 bar and 10 bar) during a dehydration phase.
