“…For example, given Almerı´a's climate, it has huge potential for solar energy desalination facilities and EU-funded field trials are being conducted in Almeria to investigate the technical and economic limitations-the AQUASOL project based on multi-effect distillation of seawater (AQUASOL, 2005). However, Herold et al (1998) andAQUASOL (2005) note that solar desalination is not yet developed at an economical level to compete with existing reverse osmosis desalination and remains, at present, better suited to small scale facilities Judgement of the sustainability of a desalination-based future is also poorly understood in the context of future global changes. For example, it may be some time before the desalination facilities come online, by which time relative energy prices may have changed.…”

“…Herold et al [75] reported the Spanish experience with its small RO plant supplied by a PV power supply fitted at the Gran Canaria Island. Finally, Khaydarov and Khaydarov proposed a new solar-powered direct osmosis process driven by natural osmosis, installed in a village in the Aral Sea region (Uzbekistan) [76].…”

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.

“…Many of these systems are comprised of the renewable energy source, batteries, and a reverse osmosis system which is designed to operate at a constant set point. Using this concept, the Canary Islands Technological Institute developed a small battery-based photovoltaic reverse osmosis (PVRO) system [3,4]. Battery-based PVRO systems have also been commercialized by Spectra Watermakers [5].…”

Many remote communities lack access to a reliable water supply. They often have access to brackish groundwater or seawater, making reverse osmosis desalination a possible solution. However, reverse osmosis desalination is an energy-intensive process and many remote communities are off the electrical grid. Determining the most economic reverse osmosis system configuration and electrical power source for a given remote community is a challenge due to their unique resource availabilities. This paper presents an optimization-based approach to compare the economics of different small-scale reverse osmosis systems and power sources for remote communities. In this approach, physical models describe the performance of electrical power systems composed of photovoltaics, wind turbines, diesel generators, batteries, and hybrid systems. These power system models are coupled to a reverse osmosis system model to determine the water production. An optimization is performed to determine the most economic power system configuration, reverse osmosis system size, and water storage size that meets the desired water production reliability. The reliability is expressed as loss of water probability, which is computed using hourly environmental data. Here, this method is used to configure a reverse osmosis system for small communities. Results are presented for locations in Honduras, Eritrea, and Australia. Results show that the local climatic conditions greatly influence the economic attractiveness of different technologies. The variety of solutions found using this approach demonstrate the ability of the method to aid in the design of a power system and reverse osmosis system configuration for any location.
