Abstract: Thermal Energy Storage systems using inorganic salts as Phase Change Materials (PCM) are ideal solutions for solar thermal direct steam generation power plants. However, the main limitation of these PCM is their low thermal conductivity. Though a composite PCM solution including graphite foam will increase the effective thermal conductivity of the storage material, the system performance is limited by the thermal contact resistance at the heat exchanger surface.
