use fossil fuels to preheat the air from 300°C to 1200°C, and the solar heat is converted with all the high thermal efficiency of a modern recuperated or combined gas turbine cycle.
Solar air preheating has great potential to reduce the costs of solar thermal power. In addition, the concept could be applied to a wide range of power levels (from 1 to 100 MW) [27]. Projects involving solar air preheating are discussed below.
