Concentrating solar power (CSP) plants require suitable thermal energy storage (TES) systems to enable power generation during the night and cloudy days. Metal hydrides (MH) are attractive options for such TES systems, and a novel design of an MH-TES system is proposed for CSP plants. The novel design of the MH-TES system is simulated for operating cycles to demonstrate its technical feasibility. The process simulation demonstrated a consistent thermal and dynamic coupling between the paired MH beds. The performance analysis showed that the present MH-TES system can recover 96% of solar energy stored. Further, for the given operating conditions, the thermal energy storage density of this system is about 90 kWhth/m3, which is more than 3.6 times the U.S. Department of Energy SunShot target of 25 kWhth/m3. Moreover, it was found that the free volume, the half time of the cycle and the desorption average temperature of the HTMH were crucial factors for improving the performance of the metal hydride reactors.
