The sunlight is caught on the parabolic reflectors, which concentrate it onto the receiver tubes. This concentrated sunlight heats up water or an alternative Heat Transfer Fluid (HTF) flowing through this receiver tube, to either 100°C or 500 °C.
The heated flow is then stored in the storage tank, which functions as the battery of the system. This heat can then be used as thermal energy or converted to electricity whenever it is needed. This inherent and cheap storage system mitigates the problem of the intermittency of renewable energies.
For the conversion of heat to electricity, the hot HTF is passed through a boiler, which turns the liquid water into steam. This steam is passed through a steam turbine, which in turn drives a generator, producing electricity.
The process from heat to steam is identical as in coal power plants, and is done using the same proven technologies, but with zero emissions. Making use of these established technologies in our system, in combination with the unlimited power of the sun, your energy bill can be reduced by as much as 70%, whilst running on fully renewable energy.
