Recently, hydropower energy resources become an attractive means of generating electricity for, off-grid networks, especially in rural areas. This work aims to design a suitable prototype of an energy-storing system, which is called a Potential Steam Hydro Capacitor (PSHC). This system gives a manageable source of electricity, and partially provides drinkable water, at a low cost, as an alternative to comparatively high-cost electrical batteries. The system is composed of two solar collectors, connected in series. The working fluid in the first collector is Dead Sea Water (DSW); and in the second fresh water, a heat exchanger, a thermosiphon solar water heater, connected to a high column to pass the vapor to high altitude, and a condensation unit, on the roof of the building. The system succeeds in producing a considerable amount of fresh water at a height of 3.4 m. The potential energy produced, can operate a small turbine. The capability of the system, to convert thermal energy in the freshwater, to potential energy, was high, with an efficiency of 66.7%. adding solar concentrators to the system would increase the water collected.
