High-temperature solar air preheating

The concentrated solar power can be used to heat pressurized air in a gas turbine before it enters the combustion chamber. There is thus no need to

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.
