Abstract:Harvesting solar energy as heat has many applications, such as power generation, residential water heating, desalination, distillation and wastewater treatment. However, the solar flux is diffuse, and often requires optical concentration, a costly component, to generate high temperatures needed for some of these applications. Here we demonstrate a floating solar receiver capable of generating 100°C steam under ambient air conditions without optical concentration. The high temperatures are achieved by using thermal concentration and heat localization, which reduce the convective, conductive, and radiative heat losses. This demonstration of a low-cost and scalable solar vapor generator holds the promise of significantly expanding the application domain and reducing the cost of solar thermal systems. Keywords: solar thermal, steam generation, thermal concentration, water treatmentThe sun is a promising and abundant source of renewable energy that can potentially solve many of society's challenges.

“…Li et al [187] in a recent review noted that solar assisted desalination has been proved technically feasible; however the combined solar and fossil fuel desalination, and desalination using low grade waste heat could be more cost effective at this time. Though solar assisted desalination processes have not been commercialized yet, with the current ongoing research, they remain a valid option for future desalination plants.…”

Renewable energy-driven desalination technologies: A comprehensive review on challenges and potential applications of integrated systems

Despite the tremendous improvements in conventional desalination technologies, its wide use is still limited due primarily to high energy requirements which are currently met with expensive fossil fuels. The use of alternative energy sources is essential to meet the growing demand for water desalination. In the last few decades a lot of effort has being directed in the use of different renewable energy (RE) sources to run desalination processes. However, the expansion of these efforts towards larger scale plants is hampered by several techno-economic challenges. Several medium-scale RE-driven desalination plants have been installed worldwide. Nevertheless, most of these plants are connected to the electrical grid to assure a continuous energy supply for stable operation. Furthermore, RE is mostly used to produce electric power which can be used to run desalination systems. This review paper focusses on an integrated approach in using RE-driven with an emphasis on solar and geothermal desalination technologies. Innovative and sustainable desalination processes which are suitable for integrated RE systems are presented. An assessment of the benefits of these technologies and their limitations are also discussed.

“…One solution to deal with the freshwater resource depletion is to desalinate seawater even if the actual energy requirement per cubic meter of water (safe for human consumption) is still high, between 2.5 and more than 12 kWh. The number of desalination systems has increased continuously in the past years totalizing a daily production of 66.4 million cubic metres of desalinated water worldwide in 2010 [31], 71.9 million m 3 in 2011 [32] and 81 million m 3 in the first quarter of 2014 [33]. A report on the geopolitical issues about water [34] highlights the importance for a country of being independent regarding water supply.…”
