Despite the tremendous improvements in conventional desalination technologies, its wide use is still limited due primarily to high energy requirements which are currently met with expensive fossil fuels. The use of alternative energy sources is essential to meet the growing demand for water desalination. In the last few decades a lot of effort has being directed in the use of different renewable energy (RE) sources to run desalination processes. However, the expansion of these efforts towards larger scale plants is hampered by several techno-economic challenges. Several medium-scale RE-driven desalination plants have been installed worldwide. Nevertheless, most of these plants are connected to the electrical grid to assure a continuous energy supply for stable operation. Furthermore, RE is mostly used to produce electric power which can be used to run desalination systems. This review paper focusses on an integrated approach in using RE-driven with an emphasis on solar and geothermal desalination technologies. Innovative and sustainable desalination processes which are suitable for integrated RE systems are presented. An assessment of the benefits of these technologies and their limitations are also discussed.

“…In fact, as shown in the previous papers [21,22], several researchers have investigated SHC, CPVT, MSF and MED subsystems one at the time. However, very few works are available in the literature investigating their integration in a single system.…”

“…In fact, the most common technologies for seawater desalination, i.e., the multi-stage flash (MSF) [18] and the multiple-effect distillation (MED) [19] systems, are both characterized by high unit energy consumptions, in the order of 30-50 kWhthermal and 3-5 kWhelectricity per m 3 of fresh water, thus resulting in high production cost; however, as the motive steam or hot water may be required at temperature as low as 75-90 °C, evident opportunities may be exploited to drive the process via heat cascades or low-temperature renewable energy sources [20]. All the above mentioned technologies (SHC, CPVT and MED) have been considered by the authors in recent works, where such novel systems were coupled with a biomass heater [21] and geothermal wells [22], designing and simulating a novel system able to simultaneously produce electricity, thermal energy for heating and cooling, and fresh water. These recent works only focused on the energy and economic analysis of the novel renewable polygeneration system proposed.…”

During the last years, special attention has been paid to renewable polygeneration technologies, able of simultaneously producing thermal, cooling, electrical energy and desalinated water from seawater. This paper focuses on an innovative polygeneration system driven by renewable energy sources, including the following technologies: hybrid photovoltaic/thermal collectors, concentrating parabolic trough (CPVT), a biomass heater, a single-stage absorption chiller and a multiple-effect distillation desalination system. The system is designed to cover the base load of an isolated small community. In previous papers, the dynamic simulation model about plant operation is discussed. In this paper, a detailed exergy, economic and environmental analysis of the plant is presented. In addition, the plant was optimized using different objective functions, applying the Design of Experiment (DoE) methodology which evaluates the sensitivity of the different objective functions with respect to the selected design parameters. The results show that an increase of the storage volume is generally negative, whereas increasing the solar field area involves an increase of the exergy destruction rate, but also an improvement of the CPVT exergy output provided; the final result is an increase of both the exergy efficiency and the economic profitability of the polygeneration system.

“…In [34,35], a poly-generation system based on PVTs, a LiBr-H 2 O chiller, and a MED distiller, with a back-up biomass heater was simulated and optimized in TRNSYS ® (http://www.trnsys.com/) with weather data from Naples, Italy. A similar scheme could be optimized in its design and operation if conventional energy sources are neglected [36].…”

Abstract:In this paper, the design of a system providing electricity by coupling photovoltaic/thermal (PVT) collectors and a wind turbine (WT), sanitary hot water (SHW) coming from the PVT and evacuated tube collectors (ETCs) and fresh water (FW) produced in two seawater desalting facilities (membrane distillation, MD, and reverse osmosis, RO), has been carefully analyzed by means of a dynamic model developed in TRNSYS ® . This analysis is compulsory to operate a lab-scale pilot plant that is being erected at Zaragoza, Spain. A new model-type has been included in TRNSYS ® in order to include the MD unit in the scheme. A sensitivity analysis of some free-design variables, such that the ETC surface, PVT and ETC tilt, water storage tank, batteries capacities, and mass flow rates delivered to the SHW service and/or feeding the MD unit has been performed in order to propose the definite design of the scheme. The proposed base case was able to produce up to 15,311 L per year in the MD system and cover an electric energy demand of 1890 kWh. Coverage of SHW, water (including RO and MD) and power is respectively 99.3%, 100% and 70%. However, daily and yearly assessment of FW, SHW and power produced with the optimized design gave a better coverage of water and energy demands for a typical single family home. The improved and definite design was able to increase its MD production in 35% and the electric energy in 7% compared with base case.
