“…The costs of electricity generation are estimated to 0.2051 USD/kWh and 0.2079 USD/kWh. The costs of water generation are from 0.8464 USD/m 3 to 0.3991 USD/m 3 for the two cases (Wellmann et al 2018). In optimum combination of site utility steam network with MED-RO desalination with the help of exergoeconomic analysis, it was found that the cost of fuel contributed the most at 88%.…”

Water and energy are two key factors in human life that always control the growth and development of human societies. Climate changes, increasing the population in urban areas and industrialization, have increased the demands for freshwater around the world. Estimates show that a small percentage of all freshwater produced in the world is from renewable sources. By developing the technology, lowering equipment prices and increasing attention to the environmental problems of fossil fuels, utilizing renewable energy is growing. By providing a wide variety of conventional desalination methods driven by various types of renewable energy technologies in the world, water and energy legislators should choose different methods to meet the needs based on the local potentials by paying attention to the desalination processes and power systems. In some cases, concentrated solar power for thermal desalination or electricity generated by the photovoltaic plants for membrane desalination systems can be used in arid areas. Definitely, the most problem of using renewable sources is their unsteady natures, which using storage systems or combining with other renewable sources can solve this problem. This chapter provides extensive information about renewables, desalination and performance analysis of power systems. Reverse osmosis technique is a practical process in desalination which 69% of desalination plants use this system. Solar energy is an important source of energy for hybrid systems. The geothermal has a steady performance at a specified depth. Ultimately, obtained results from energy and exergy analysis would have provided a better insight.

“…All thermal desalination plants require electrical energy to pump the different media (Micale et al., 2009). The dominant thermal desalination technologies are MSF and MED (Ghaffour et al., 2015; Trieb et al., 2007; Wellmann et al., 2018). Figure 2 shows the various seawater desalination technologies and their shares worldwide (Wellmann et al., 2018).…”

This study analyzes a technological concept for simultaneously generating power and desalinating water in a Middle East and North Africa country. An innovative, low-temperature, multi-effect desalination (LT-MED) process integrated with a concentrating solar power (CSP) plant was assessed and analyzed. A combined power and seawater desalination plant was modeled for the city of Aqaba by the Red Sea in Jordan. Parabolic-trough collectors using indirect steam generation with thermal energy storage connected with power and desalination blocks were designed. The designed plant was modeled and simulated using EBSILON Professional, a discrete energy balance simulation software, under several operating conditions, to analyze the results. An economic feasibility analysis of the combined CSP+LT-MED plant was also conducted. The simulation results showed the broad variability of the cogeneration system in terms of electricity generation and water production. The output power of the CSP plant without water production reached 58.7 MWel in June. The output power accompanied with distilled-water production with a mass flow rate of 170 m3/h was approximately 49.5 MWel. Furthermore, the number of desalination stages had the strongest influence on distillate production but limited the operational flexibility of the power plant due to the temperature gradients within the desalination stages. The distilled-water mass flow reached 498 m3/h for 10 stages. The research showed that the design successfully worked with up to €78.84 million, earned from selling the produced electricity. However, owing to highly subsidized water tariffs in Jordan (80% less than the actual cost), the integration of water desalination into the CSP plant was not economically feasible.

“…Several studies have found that renewable powered desalination is cost-effective primarily in remote locations (e.g., [9]). The possibility of driving desalination systems using heat engines powered by concentrating solar thermal production collectors has generally appeared less economically feasible than PV [16][17][18], but is viewed by some as a promising technology, especially in the medium term [8,19].…”

The Levant area of the Middle East suffers from both chronic water scarcity and high population growth. It is also a region highly dependent of fossil fuels. In order to address current and expected water demands, several countries in the region, including Israel, Jordan and the Palestinian Authority (PA), are depending increasingly on desalination, which is expected to intensify energy consumption and energy related emissions. Given that the region also benefits from high levels of solar irradiation nearly year-round, much attention has been given to the possibility of developing renewable energy in general and for desalination specifically. This paper presents partial results of a pre-feasibility study assessing the prospects of transfers of desalinated water from Israel and/or the PA, which have access to the Mediterranean Sea, to Jordan, in exchange for renewable solar-produced electricity from Jordan, which, unlike its neighbors, has an abundance of available open space suitable for solar production. The analysis shows that single-axis tracking photovoltaic (PV) systems appear to be the most economically feasible option. Moreover, the study shows that the proposed idea of international cooperation and water-energy exchanges, while facing political obstacles, could provide numerous economic, environmental and geopolitical benefits to all parties involved. As such, an arrangement such as that examined may be a more promising means of promoting both desalination and renewable energy than if each country unilaterally develops desalination and renewable energy in isolation from one another.
