“…RO technology generally requires less total thermal and electrical energy (3-4 kWh/m 3 ) than other conventional commercial desalination technologies, such as multistage flash distillation or multiple-effect distillation (5.5-16 kWh/m 3 ) [3,[5][6][7][8]. By 2015, RO technology achieved remarkable gains in the production of desalinated water from seawater (6.9 km 3 year −1 of the 12.9 km 3 year −1 total global desalinated water production from seawater reported in the DesalData database [9]).…”

Seawater desalination is a promising approach to satisfying water demand in coastal countries suffering from water scarcity. To clarify its potential future global scale, we perform a detailed investigation of the economic feasibility of desalination development for different countries using a feasibility index (F i ) that reflects a comparison between the price of water and the cost of production. We consider both past and future time periods. For historical validation, F i is first evaluated for nine major desalination countries; its variation is in good agreement with the actual historical development of desalination in these countries on both spatial and temporal scales. We then simulate the period of 2015-2050 for a Shared Socioeconomic Pathway (SSP2) and two climate scenarios. Our projected results suggest that desalination will become more feasible for countries undergoing continued development by 2050. The corresponding total global desalination population will increase by 3.2-fold in 2050 compared to the present (from 551.6 × 10 6 in 2015 to 1768 × 10 6 ). The major spread of seawater desalination to more countries and its availability to larger populations is mainly attributed to the diminishing production costs and increasing water prices in these countries under the given socioeconomic/climate scenarios.

“…Einav et al 46 reported that a SWRO plant with a 100 million m 3 •year -1 production requires 25 acres of area, which means a direct land use of 1.012•10 -between 2.6 kWh and 8.5 kWh. 47 As a particular example, Las Palmas III-IV (Spain) SWRO desalination plant presents an energy consumption of 3.0 kWh•m -3 , 48 while the average energy consumption in SWRO desalination plants in Israel is about 3.5 kWh•m -3 . 49 These values will be taken as a preferred reference for Spain and Israel, respectively.…”

“…Table 1. Specific energy consumption, as reported in literature [9,16,17,[19][20][21][22][23][24][25][26][27][28], varies for different desalination technologies. Total equivalent specific energy consumption is equal to the sum of kilowatt-hours (electric) and kilowatt-hours (thermal), converted based on an assumed 45% efficiency of a modern power station [16]: equivalent electric kWh/m 3 = kWh e /m 3 + 0.45 kWh th /m 3 .…”

Desalination is often considered an approach for mitigating water stress. Despite the abundance of saline water worldwide, additional energy consumption and increased costs present barriers to widespread deployment of desalination as a municipal water supply. Specific energy consumption (SEC) is a common measure of the energy use in desalination processes, and depends on many operational and water quality factors. We completed multiple linear regression and relative importance statistical analyses of factors affecting SEC using both small-scale meta-data and municipal-scale empirical data to predict the energy consumption of desalination. Statistically significant results show water quality and initial year of operations to be significant and important factors in estimating SEC, explaining over 80% of the variation in SEC. More recent initial year of operations, lower salinity raw water, and higher salinity product water accurately predict lower values of SEC. Economic analysis revealed a weak statistical relationship between SEC and cost of water production. Analysis of associated greenhouse gas (GHG) emissions revealed important considerations of both electricity source and SEC in estimating the GHG-related sustainability of desalination. Results of our statistical analyses can aid decision-makers by predicting the SEC of desalination to a reasonable degree of accuracy with limited data.
