Perspectives of solar-assisted seawater distillation

improvements of thermal solar and seawater distillation technologies were considered in order to analyze the perspectives of the competitiveness of solar vs. conventional energy in seawater desalination.

Indirect solar desalination has interesting potential for development. Nevertheless, intensive research is necessary, especially to improve the reliability of solar heat pumps and DSG parabolic troughs or to increase the top brine temperature. In addition, the use of steam generated by solar energy to drive a RO plant may be a promising alternative to solar distillation.
