“…[ 205 ] The technoeconomic analysis of the integration system of RO with CSP and PV plant indicated that the fresh water production operation of RO is more suitable with the adaptation to the power fluctuation. [ 206 ] With the presence of TES with high storage capacity up to 14 h, CSP‐driven RO is technically and economically more favorable than the integration of RO and PV. As one of the emerging desalination processes, MD shows very high flexibility in tapping solar energy.…”

With the change in climate patterns, rapid industrialization, and population growth, the increasing water and energy demand became a major concern in the past decades. Desalination has been touted as the answer to the global water crisis, due to its capability in producing high‐quality fresh water from saline water. The continual research and innovations in the desalination field have resulted in the commercialization of large‐scale desalination in many water scarce regions. In the energetic context, all desalination processes are energy intensive. With the necessity to make desalination a more affordable and sustainable process, the energy efficiency of desalination is becoming an important topic. Herein, it is aimed to provide insights into the recent efforts and strategies established to tackle the energy‐related issues of both, thermal‐based and membrane‐based desalination processes. Depending on the principle of various commercial and emerging desalination processes, the directions of energy efficiency improvements, which include operating condition optimization, high‐performance material development, and renewable energy exploitation are discussed. The ideas and strategies reviewed herein, whether in their implementation or theoretical stage, are expected to provide insights into the possible improvement for application in commercial desalination plants.

“…In this regard, several studies have demonstrated that CSP + RO integration presents the best cost-benefit option because the desalination process represents just another electrical load for the plant. Thus, plants can be located at different strategic sites, improving their overall performance (Aboelmaaref et al, 2020;Laissaoui et al, 2018). However, the hybridization of MED and RO desalination systems can achieve even better performance and a cost-benefit relationship (Iaquaniello et al, 2014).…”

Concentrated solar power (CSP) technologies have been developed over the past four decades for commercial operation, establishing them as reliable power generation sources in regions with high direct solar irradiance. The sizing of the solar field, thermal energy storage systems, and power block enables CSP plants to operate under various operating conditions, while also exhibiting capabilities to generate multiple products such as electricity, heat, desalination, and cooling.The limitations of CSP systems can be reduced by utilizing the positive traits of other technologies, thus resulting in hybrid plant configurations that can fully exploit different technology strengths while minimizing their individual weaknesses. This review presents the state of the art on CSP stand-alone plants for both power generation and combined generation of different products. Subsequently, the characteristics of CSP plants hybridized with photovoltaics, wind, fossil fuels, and biomass systems are discussed for both power multiple-product generation. The review of assessment methodologies provides suggestions for both assessment and performance analysis and comparison with other generation technologies. This review shows that hybrid CSP plants have clear advantages in terms of cost, flexibility of operation, adaptability, and capability for the multigeneration of different products compared with stand-alone plants used to generate each product individually. Hybrid CSP plants have advantages and can be designed to satisfy multiple demands on a case-by-case basis and are valid alternatives to combinations of stand-alone plants.

In this paper, a new modeling technique of a seawater reverse osmosis (RO) desalination plant fed by hybrid renewable energy sources is provided. The proposed model consists of five subsystems including RO plant model, photovoltaic (PV) model, horizontal wind turbine (HWT) model, battery model and the control room unit. In the RO model, the process is optimized to have the lowest specific energy consumption under different operating conditions and variable productivity ranging from 100 to 10000 m 3 per day. However, in the PV and HWT models, various manufacturing datasheets for PV panels and wind turbines are stored at different power ratings. The model allows the selection of appropriate design specifications based on average solar radiation and average wind speed at the site. In addition, the total battery storage, Ampere-hour capacity and other specifications are calculated in the battery model. The control room unit is responsible for calculating the total annual costs and the cost of fresh water production according to the plant productivity, lifetime and interest rate. It has a splitter control ratio to regulate the load distribution between PV and wind turbines relative to changes in climatic conditions. The model is simulated using Matlab/Simulink and provides good results for model validation.
