“…For example, based on a techno-economic feasibility study of a 20 m 3 /d RO plant in Abu Dhabi, it was found that a fully solar driven unit without batteries with a cost of water of 7.34 $/m 3 would be competitive compared with a fully diesel powered unit (7.64 $/m 3 ) [ 15 ]. In general, when solar resources are abundant, PV-RO is found to be more competitive than diesel powered units [ 16 , 17 ]. However one limit of PV-RO design is the intermittency of solar PV generation that can be smoothed using storage device to allow a 24 h steady state operation mode of the PV-RO desalination unit [ 18 ].…”

This paper examines the cost competitiveness of an extra-large-scale (275,000 m 3 /d) solar-powered desalination, taking as a case study the Chtouka Ait Baha plant in Morocco. It assesses the conditions at which solar Photovoltaics (PV) and Concentrated Solar Power (CSP) would be competitive with a grid (mainly fossil) driven desalination plant for the reference year and by 2030. The paper considers also a scenario where battery storage complements PV power generation. To conduct the analysis, a simple model of water cost calculation is built. Second, the cost related to energy consumption is calculated for different power supply options to evaluate the impact of energy provision cost on the final cost of water. The first main result of this paper is that desalinated water can be obtained at an acceptable cost of around 1 $/m 3 . The second one is that PV without storage remains the cheapest power supply option today and by 2030. Storage based solution appears less competitive today but can be more attractive in a framework of increasing electricity grid prices and higher flexibility requirements in the future. The paper gives recommendations regarding the implication of different technology choices in the framework of the future Moroccan energy system.

“…Hence, water production cost from PV-RO systems is highly site dependent. Numerous studies[43,44,[74][75][76][77] discussed the feasibility of PV-RO systems and suggested different configurations that may offer high feasibility.Mohamed et al[43] compared the performance of a RO plant using batteries for energy storage against another plant that is directly coupled to a PV array. The directly coupled plant offered less complexity since there is no need for batteries or a charge controller.…”

“…The directly coupled PV-RO plant produced water at the most competitive price. In general, PV-RO systems were found to be economically more feasible than Diesel-powered systems provided there is sufficient solar resource[74,76,77].The economic feasibility of a RO plant operated by an organic-solar Rankine cycle was compared to that of a directly coupled PV-RO system by Manolakos et al[75]. Water production cost for the PV-RO system was significantly lower than that of the organic-solar Rankine-RO system at 7.77 €/m 3 compared to 12.53 €/m 3 .…”

The use of Reverse Osmosis (RO) desalination has grown considerably in response to water scarcity. Despite steady improvements in efficiency, RO desalination remains an energyintensive process. Numerous studies focussed on using mature Renewable Energy Sources (RES), such as wind and solar photovoltaic (PV) energy, to drive RO plants on a small scale. However, RES have not been used to drive large plants, except with a grid connection, due to the intermittency and fluctuation of such sources. Direct coupling of the RO plant to a RES requires variable-speed operation and/or modular operation to match the load to the available power. This review presents the state-of-the-art in wind and solar-PV powered RO to identify technical challenges and potential solutions regarding large-scale implementation. Recent studies using wind and solar-PV to drive RO are analysed while considering the plant configuration, operational strategy, control system and methods used to improve the plant adaptability to the RES. Technical challenges may include shortened membrane life and 2 reduced performance of energy recovery devices. Potential strategies for incorporating modular and variable-speed operation in commercial RO plants are presented. Control strategies are reviewed, including Model Predictive Control, Neural Networks and classical Proportional-Integral-Differential feedback control. Recommendations are made on future research necessary for operation of commercial RO plant operation from renewable energy.
