“…Storing energy in hydrogen is another option, but the conversion efficiency must be improved at both ends. For short-term fluctuations, flywheels [41], supercapacitors [42] or compressed air storage [43] is options to develop. In the case of already-dispatchable CSP, the development of more efficient Brayton cycles that operate with air or supercritical CO 2 is proposed [44].…”

Water and energy are two strategic drivers of sustainable development, intimately interlaced and vital for a secure future of humanity. Given that water resources are limited, whereas global population and energy demand are exponentially growing, the competitive balance between these resources, referred to as the water-energy nexus – is receiving renewed focus.The desalination industry alleviates water stress by producing freshwater from saline sources, such as seawater, brackish or groundwater. Since the last decade, the market has been dominated by membrane desalination technology, offering significative advantages over thermal processes, such as lower energy demand, easy process control and scale-up, modularity for flexible productivity, and feasibility of synergic integration of different membrane operations. The exciting new frontier of sustainable mining of seawater concentrates is accelerating the appearance of a plethora of innovative membrane materials and methods for brine dehydration and selective extraction of trace ions, although under the sword of Damocles represented by cost feasibility for reliable commercial application. On the other hand, among several emerging technologies, reverse electrodialysis (SGP-RED) was already proven capable – at least at the kW scale–of turning the chemical potential difference between river water, brackish water, and seawater into electrical energy. Efforts to develop a next generation of Ion Exchange Membranes exhibiting high perm-selectivity (especially toward monovalent ions) and low electrical resistance, to improve system engineering and to optimize operational conditions, pursue the goal of enhancing the low power density so far achievable (in the order of a few W per m2).This Roadmap takes the form of a series of short contributions written independently by worldwide experts in the topic. Collectively, such contributions provide a comprehensive picture of the current state of the art in membrane science and technology at the water-energy nexus, and how it is expected to develop in the future

“…Energy storage in the form of batteries still involves high investment costs, but fortunately the operational lifetime of newer technologies (e.g., lithium-ion) is increasing. Other novel energy storage technologies have also been proposed in literature for desalination such as compressed air storage [63]. Hybrid systems, in combination with performance optimization schemes and energy management systems, can also provide viable solutions [64,65].…”

Renewable Energy Desalination for Island Communities: Status and Future Prospects in Greece

2022

Energy and water are two of the most important components required to ensure prosperity and sustainable development to societies. This paper aims to review the status of renewable energy desalination for Greek islandic communities, deployed in two axes. The first one reviews the desalination systems state of the art technological solutions, their energy needs, how renewable energy may be employed and finally the cost of renewable energy desalination is investigated. The second axis focuses on Greek islands per se, where the current situation is investigated, potential solutions for meeting the water needs are evaluated, all leading to the proposal of a methodology towards designing an appropriate and applicable approach in addressing the water needs. Finally, a discussion takes place on how such options might be further deployed, particularly regarding the impacts they may produce for the livelihood and the future prosperity of the pertinent communities, and at the same time supporting the energy transition towards the EU Green Deal goals.
