Solar thermal power plants
Whether for electricity supply or for process steam generation, with a storage system or as an integral solution in combination with a conventional power plant, solar thermal power plants are attractive, both ecologically and economically.
Energy around the clock
In a solar energy plant, the heat recovered is dependent on the sun and its fluctuating radiation. In order to nevertheless provide constant power, two technically proven concepts are available: solar thermal storages, like we use it in the solar thermal power plant Andasol 3, and hybrid power plants, or a combination of both.
With the parabolic trough technology between 10 and 200 MW of electricity can be produced. Heat generates water vapor to drive a turbine that supplies the energy. The enlargement of existing plants, a location with high solar irradiance and falling costs of components make power production competitive with conventional power plants in the medium term. A combination with thermal storages guarantees a continuous supply during all times of the day.
In hybrid power plants, solar energy is used in addition to fossil or biogenic fuels. Through this combination, solar thermal power plants can also operate continuously at base load even when the radiation available is fluctuating, or conventional power plants can be made even more efficient. For example, the integration of a solar field into a combined cycle power plant raises profitability by improving the capacity utilisation of the turbines, by buffering absent solar energy and through the good combined costing of the power mix.
