“…However, the development of this desalination system has not yet reached its full potential and proceeds continually while the newest scientific articles mentions the possibility of new applications that use this technology [16][17][18]. The numerical model of the thermal desalination unit [4,19] has been created in cooperation with the project engineers of an existing pilot plant using the kernel scripting module of Ebsilon [3,4,20]. A time series analysis of the extensive meteorological data of the given location [5] have been executed in order to determine the optimal design parameters for the plant and to calculate annual electricity and water production.…”

“…• Avoiding surplus power: In the best case, the generation of surplus power could be avoided through optimal design. The design of the CSP with the thermal desalination unit allows a flexible condensation pressures which shift the power generation to more water production [3,4]. Due to the fact, that water can be easily stored, the surplus electricity generation could be reduced to a certain extent.…”

“…This paper focuses on the integration of a concentrating solar power (CSP) plant with attached thermal seawater desalination [3,4] into a real demand scenario of a city in Egypt and the assessment to what extent the energy and water demand can be covered by this technology. Due to the availability of meteorological [5] as well as power and water demand data [6,7], the city of El Gouna is chosen.…”

The paper discusses a supply and demand scenario using renewable energy sources for the city El Gouna in Egypt as an example for a self-supplying community. All calculations are based on measured meteorological data and real power demand during the year 2013. The modeled energy system consists of a concentrating solar tower plant with thermal storage and low-temperature seawater desalination unit as well as an integrated photovoltaic plant and a wind turbine. The low-temperature desalination unit has been newly developed in order to enable the utilization of waste heat from power conversion processes by improved thermal efficiency. In the study, special attention is given to the surplus power handling generated by the photovoltaic and wind power plant. Surplus power is converted into heat and stored in the thermal storage system of the solar power plant in order to increase the capacity factor. A brief estimation of investment costs have been conducted as well in order to outline the economic performance of the modeled energy and water supply system.

“…The energetic and exergetic efficiencies for the multi-stage configuration were found to be greatly improved compared with the single-effect system. Wellmann et al [14,23] reported a multi-stage SLTD system driven by the waste heat of a CSP (concentrated solar power) plant. The desalination cost was calculated to be 0.4-0.85 USD/m 3 , depending on the electricity cost.…”
