“…The use of MEDAD has an additional advantage in which it generates potable water at low temperatures, which minimises fouling and scaling. Furthermore, Mabrouk et al [61][62] developed a novel design of MED system, which obtains a higher GOR by reducing the effective evaporator surface area, i.e. enhanced heat transfer through the evaporator.…”

“…Moreover, the team studied the techno-economic aspects of the MSF-MED hybrid desalination process and reported that MSF-MED system yields 21% lower LCOW as compared with MED-TVC and 32% lower than MSF-Brine Recycling. Also, the pumping power reduced for MSF-MED by 58% and 16% as compared with MSF-Recycling Brine and MED-TVC, respectively [62]. The team concluded that MSF-MED is the best thermal technology for the GCC Preprints (www.preprints.org) | NOT PEER-REVIEWED | Posted: 4 December 2019 doi:10.20944/preprints201912.0048.v1…”

Desalination accounts for 1% of the total global water consumption and is an energy-intensive process, with the majority of operational expenses attributed to energy consumption. Moreover, at present, a significant portion of the power comes from traditional fossil fuel-fired power plants and the greenhouse gas emissions associated with power production along with concentrated brine discharge from the process, pose a severe threat to the environment. Due to the dramatic impact of climate change, there is a major opportunity to develop sustainable desalination processes to combat the issues of brine discharge, greenhouse gas emissions along with a reduction in energy consumption per unit of freshwater produced. Nanotechnology can play a vital role to achieve specific energy consumption reduction as nanofluids application increases the overall heat transfer coefficient enabling the production of more water for the same size desalination plant. Furthermore, concentrated brine discharge has a negative impact on the marine ecosystems, and hence, this problem must also be solved to support the objective of sustainable desalination. Several studies have been carried out in the past several years in the field of nanotechnology applications for desalination, brine treatment and the role of renewable energy in desalination. This paper aims to review the major advances in this field of nanotechnology for desalination. Furthermore, a hypothesis for developing an integrated solar thermal and nanofluid sustainable desalination system, based on the cyclic economy model is proposed.

“…Concomitantly, the deep sea beds at 300 to 600m act as an infinite supply of cold water where the temperatures hover from 10 o C to 4 o C. Seawater temperature gradient is shown in Figure 5(a) and potential location is presented in Figures 5(b, c). process is well proven [25][26][27][28][29][30][31][32][33][34][35] and it is thermodynamically suited for exploiting low temperature difference, 20 o C K, available in seawater thermocline. There is boundless supply of renewable seawater thermocline energy between the tropics of Cancer and Capricorn throughout the year for sustainable production of fresh water:-The parasitic electricity is consumed by the warm and cold seawater pumps and the vacuum pump.…”

A multi evaporator desalination system operated with thermocline energy for future sustainability

et al. 2018

All existing commercial seawater desalination processes, i.e. thermally-driven and membranebased reverse osmosis (RO), are operated with practical performance ratios (PPRs) varying up to 90, whilst the PPR for an ideal or thermodynamic limit (TL) of desalination is at 828. Despite slightly better PPRs for the RO plants, all practical desalination plants available, hitherto, operate at only less than 11% of the TL, rendering them highly energy intensive and unsustainable for future sustainability. More innovative desalination methods must be sought to meet the needs of future sustainable desalination and these methods should attain an upper PPR bound of about 25 to 30% of the TL. In this paper, we examined the efficacy of a multi-effect distillation (MED) system operated with thermocline energy from the sea; A proven desalination technology that can exploit the narrow temperature gradient of 20 o C all year round created between the warm surface seawater and the cold-seawater at depths of about 300-600 m. Such a seawater thermocline (ST)-driven MED system, simply called the ST-MED process, has the potential to achieve up to 2 folds improvement in desalination efficiency over the existing methods, attaining about 18.8% of the ideal limit. With the major energy input emanated from the renewable solar, the ST-MED is truly a "green desalination" method of low global warming potential, best suited for tropical coastal shores having bathymetry depths of 300 m or more.

“…Reverse Osmosis are modular and scalable units relatively efficient, less-expensive, and easy to replace [23]. The current worldwide market share is almost 33% for phase-change methods compared to 67% for non-phase change methods [24]. (3) Hybridization method: This refers to types of hybrid processes which combine two processes used for the desalination processes (e.g., RO + MED).…”

Water Storage Instead of Energy Storage for Desalination Powered by Renewable Energy—King Island Case Study

Abstract:In this paper, we scrutinized the energy storage options used in mitigation of the intermittent nature of renewable energy resources for desalination process. In off-grid islands and remote areas, renewable energy is often combined with appropriate energy storage technologies (ESTs) to provide a consistent and reliable electric power source. We demonstrated that in developing a renewable energy scheme for desalination purposes, product (water) storage is a more reliable and techno-economic solution. For a King Island (Southeast Australia) case-study, electric power production from renewable energy sources was sized under transient conditions to meet the dynamic demand of freshwater throughout the year. Among four proposed scenarios, we found the most economic option by sizing a 13 MW solar photovoltaic (PV) field to instantly run a proportional RO desalination plant and generate immediate freshwater in diurnal times without the need for energy storage. The excess generated water was stored in 4 × 50 ML (mega liter) storage tanks to meet the load in those solar deficit times. It was also demonstrated that integrating well-sized solar PV with wind power production shows more consistent energy/water profiles that harmonize the transient nature of energy sources with the water consumption dynamics, but that would have trivial economic penalties caused by larger desalination and water storage capacities.
