Technologies for large scale seawater desalination using concentrated solar radiation

This paper shows the principles and the present state of the art of concentrating solar power technology and explains the option for seawater desalination, either using electricity or steam generated in such plants. The economic potential of this technology in the MENA region can cope with the present and the expected future demand of electricity and water. First projects are now being realized, for electricity and also for combined heat and power for desalination, electricity and cooling.
