−	Using different approaches to store the excess solar energy into '''thermal energy storages (TES)''' it is possible to run a CSP plant around the clock, 24 hours a day and therefore in baseload. For storing thermal energy so-called Phase Change Materials (i.e. water) are applied to make use of the latent heat. In addition thermal-chemical storages can offer even higher storage capacities making use of the chemical reactions taking place due to adsorption and absorption. A commonly used TES is molten salt while other TES are currently under investigation (see [https://www1.eere.energy.gov/solar/sunshot/csp_storage_ussh.html SunShot Initiative]).~~<br/>~~	+	Using different approaches to store the excess solar energy into '''thermal energy storages (TES)''' it is possible to run a CSP plant around the clock, 24 hours a day and therefore in baseload.

-These receivers are mobile applications. They are moving on a 1-axis-tracking system according to the sun's movement. It is a simpler application for tracking the sun than a point focus system (power tower or dishes) that needs to track the sun along two axes. This system, however, consists of parallel rows of reflectors or mirrors. Absorber tubes made of stainless steel serve as the heat collectors. The selective coating on these absorber tubes allows to absorb high levels of solar radiation while only few energy is lost again through infra-red radiation. The absorber tubes are insulated in an evacuated glass envelope. The heat transfer fluid used is synthetic oil. The oil is transferred through the tubes to a heat exchanger which heats and then superheats water into superheated steam. The steam is then expanded in a turbine which runs a generator to produce electricity. The water is then cooled, condenses and returns to the heat exchangers.

-The power tower really lives up to its promise. Compared to other CSP technologies, it can create the highest degree of temperature. Surrounded by mirrors reflecting light onto an elevated and centered tower, the power tower generates heat of about 1,000 C°.<ref>Taggart, S.

The Linear Fresnel arrangement approximates the parabolic shape of trough systems. It is a simple receiver design that facilitates direct steam generation.

The fluid or gas is then used to drive a micro turbine or Stirling engine which is attached to the receiver.
