The aim of this work is to analyse whether the integration of Multi-Effect Distillation (MED) process into … production by connecting a Reverse Osmosis (RO) system to a CSP plant. For this purpose, different CSP + MED configurations using … the steam from the turbine as the thermal energy source of the desalination process have been evaluated and compared to …

Single cooling and desalination technologies require a high amount of energy to produce cooling and fresh water … appears also interesting. The major increases in cooling and desalination demands occur in locations where solar energy is … abundant. This article reviews the latest research works on systems able to carry out cooling and/or desalination using solar …

Seawater desalination is an important process to meet the increasing demand for fresh water demand; however, it is … highly energy intensive due to the high salinity of the source. Studies on using solar energy to drive seawater desalination … are very actively being pursued. This paper reviews the current solar desalination research activities first, followed by …
