“…Obtained results from this study declared that the cost of desalinated water evaluated for HP-HDH air-heated system and HP-HDH water-heated cycle varies from 4.61 $/m 3 to 5.49 $/m 3 and 6.00 $/m 3 to 7.14 $/m 3 , respectively (Lawal et al 2018). In another study, an exergoeconomic analysis of a forward-feed multi-effect mechanical VC desalination system has been performed.…”

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.

“…In addition, the maximum GOR of the system reached 13.5 using R-22 as a refrigerant at MR of 0.56. Lawal et al 141 presented an exergoeconomic study for the air heating system of the HDH desalination systems in which the heat pump cycle employed as a heating source. The results indicated that the exergy efficiency of WDS was 1.097%, and the fresh water cost varied from $4.61/m 3 to $5.49/m 3 .…”

Summary The lack of fresh water resources is one of the important reasons obstructing progress all over the world. To overcome this crucial situation, the water desalination system (WDS) is progressed, enhanced, and modified. The desalination plant is mostly powered by nonrenewable energy resources, mainly by fossil fuels that make it an expensive and high‐energy‐consuming technology. Therefore, it is indispensable to depend on renewable energy supplies to drive desalination systems. Recently, the total thermal energy desired to operate the humidification–dehumidification desalination systems can be gained from renewable/sustainable energy resources such as geothermal energy and solar energy. Among the different desalination techniques, the HDH is considered one of the most effective desalination techniques to manage the critical issue of shortage of drinking water. The current paper presents a comprehensive review of diverse types of HDH desalination systems as well as their fundamental components. The present work revealed that the seawater HDH system is a promising technology to produce fresh water, particularly for decentralized demand. The packed bed humidifier is the most utilized type in the HDH water desalination system than other types of humidifiers. Furthermore, the direct dehumidifier enhances the performance of HDH desalination system compared to the indirect one. The present study concludes that the hybrid energy systems have the highest gain output ratio, while the thermal energy systems have the lowest gain output ratio. Water heating with solar energy has a significant enhancement in system productivity compared with solar air heating. The HDH WDS incorporated with heat pump achieves appropriate system productivity and gain output ratio with the lowest cost per liter.
