“…In the average, producing 1000 cubic meters of fresh water by desalination technology consumes about 5 tons of crude oil which produces about 10 tons of carbon dioxide or about 5000 cubic meters of greenhouse gases [13,14]. The total global desalination capacity has witnessed a severe increase within the last few years, from 66.48 million cubic meters per day in 2011 to 86.6 million cubic meters per day in 2015 [7,15]. Therefore, serious forward steps toward integrating the desalination systems with the renewable and sustainable energy technologies will be required to mitigate the negative effects of the desalination systems.…”

Water and energy are indispensable entities for any flourishing life and civilization. The water and energy scarcities have emerged due to the dramatic growth in the population, standards of living, and the rapid development of the agricultural and industrial sectors. Desalination seems to be one of the most promising solutions to the water problem; however, it is an intensive energy process. The integration of the renewable energy into water desalination systems has become increasingly attractive due to the growing demand for the water and energy, and the reduction of the contributions to the carbon footprint. The intensive investigations on the conventional desalination systems, especially in the oil-rich countries have somewhat overshadowed the progress and implementation of the renewable energy desalination (RED) systems. The economic performance evaluation of the RED systems and its comparison with conventional systems is not conclusive due to many varying factors related to the level of technology, the source of energy availability, and the government subsidy. The small RED plants have a high capital cost, low efficiency and productivity which make RED systems uncompetitive with the conventional ones. However, the selection of the small RED plants for the remote arid areas with small water demands is viable due to the elimination of the high cost of the water transportation, and the connection to the electricity grid. The purpose of this paper is to review the technology, energy, and cost of the recent available desalination systems and their potential to be integrated with the renewable energy resources. This review suggests that the solar still distillation (SD) system, which is simply a natural evaporation-condensation process, is the most practical renewable desalination technique to be used in the remote arid areas; however, a further research is required to enhance their performance and to increase the productivities of these systems.

“…In this study, we focus on potential ecological indicators, but they can clearly be integrated into the broader issues of desalination ecosystem damage and can be used as important ecological indicators in future policy decisions. Consequently, many studies investigated the monitoring bar, ecological impact and/or risk assessment of seawater desalination plants, the effects of alkalinity changes, entrainment, increased salinity, impingement, temperature increase, and thermal pollution and become available biocide, antiscaling additives, antiforming additives, coagulants, chemical cleaning, other physical factors of marine ecosystem have is led to the development of potential ecological indicators to biochemical metabolic condition, heavy metal pollution, and biological stress [16][17][18][19][20][21]. Scientists have also applied these potential eco-indicator species and/or ecotoxicological effects to plant organism of seawater desalination plant procedure, new eco-problems of desalting, and ecosystem quality assessment on marine community [9,22,23].…”

“…The technology is used to alleviate shortages in drinking water in coastal areas due to changing weather patterns, recurring droughts, saltwater intrusion into coastal aquifers, and growth of coastal populations and industries. Despite the advantage of providing a water supply option independent of climate, seawater desalination plants also have the potential to negatively impact coastal ecosystems and communities, depending on the design, locations, and local context of these plants [22,43,8]. Examples of socio-economic impacts include increased price of water -since the technology is relatively expensive [10,15,33,63,9], loss of public access to coastal areas, disruption of commercial and recreational activities, and aesthetic alterations of coastal landscapes [43,6,64].…”

Indirect environmental impacts on marine ecosystems, such as ocean acidification and sea-level rise, may occur due to the high energy consumption of desalination plants and subsequent increase in greenhouse gas emissions [46,9].…”

Management priorities for seawater desalination plants in a marine protected area: A multi-criteria analysis

et al. 2017

The development of seawater desalination plants to increase water reliability in coastal areas poses a threat to the health of near shore marine ecosystems and may affect the effectiveness of marine protected areas (MPAs) that have been established to meet international conservation targets. This paper applies a multi-criteria analysis approach to quantify stakeholder groups' priorities for seawater desalination plants that have been proposed in communities adjacent to a National Marine Sanctuary. All groups placed the highest importance on minimizing environmental impacts on protected areas and endangered species that could be affected by water intake and brine discharge emphasizing the need for integrated land and sea conservation. Minimizing socio-economic impacts on coastal communities was much less important. Stakeholders also weighted reducing pressure on water levels in rivers, streams, and aquifers as more important than increasing water for residential consumption, which may foster coastal growth rather than replacing water taken from other sources. The study further revealed differences in the importance of multiple management objectives among stakeholder groups, which highlights the need to elicit distinct priorities of all groups to understand concerns and potential conflicts of desalination with existing marine users. The analysis of consistency ratios revealed that around half of all surveyed stakeholders had high inconsistencies in their responses, which suggests either a lack of understanding of desalination, or reflects the complexity of establishing desalination plants in coastal areas adjacent to a marine protected area.
