The ETSAHP module includes a transparent or semi-transparent tube configured to receive heat input from solar energy, the tube having a hollow interior, a top section, and a bottom section opposite the top section, an adsorbent bed comprising a plurality of adsorbent beads and positioned at the top section of the tube and configured to absorb solar energy, an adsorbent bed cage configured to contain the adsorbent bed at the top section of the tube, a threshold configured to stabilize the adsorbent container within the tube, and a condenser/evaporator positioned at the bottom section of the tube and spaced apart from the adsorbent bed.

A single-phase fluid (SPF) storage is introduced for desalination of high-salt water using thermal energy from a concentrated solar power (CSP) unit. The SPF having a specific volumetric enthalpy higher than that of water at critical point in the operating ranges from 20 to 300 bar in pressure and 190 to 400 C in temperature is used as a new type of thermal energy storage (TES) medium and heat transfer fluid (HTF). It produces wet steam of a quality required by the desalination unit generating both steam for utilization of latent heat and condensate for sensible heat when its pressure is reduced to lower operating pressures. With a MED-TVC unit by using the steam as motive steam, the capacity of the CSP unit and SPF storage can be reduced as much as the energy recycled in the desalination unit.
