Among renewable technologies, Concentrated Solar Power (CSP) plants are seen as an attractive option to reduce pollutants and the emission of greenhouses gases (e.g. CO2) not only for the United States regions of the Sun Belt (where CSP plants are in commercial use for more than 20 years [1]), but also for European Union, North Africa and Middle East. CSP technologies are based on the concept of concentrating solar radiation to be used for electricity generation within conventional power cycles using steam turbines (most mature and common technology, gas turbines or Stirling engines).CSP Solar tower plants can achieve high operating temperatures of over 1000 °C, enabling them to produce hot air for gas turbine operation. Solarized hybrid Gas Turbines can be used in combined cycles, composing a Solar Hybrid Combined Cycle yielding conversion efficiencies of more than 50 % (fig.1), this being a leap in performance for solar energy conversion.
