In a Concentrating Solar Power (CSP) plant, the sun’s thermal energy is concentrated by mirrors. A heat transfer fluid - either thermal, molten salt or liquid sodium - is used to transfer the energy to the steam generator. The steam generator is part of a conventional water steam cycle generating electricity via a steam turbine and an electrical generator. Beside the on-going electricity production, the thermal energy is partially stored in heat storage tanks using molten salt, in order to enable electricity production during the night-time. After the sunset the stored heat can be used to continue production for some 8 hours or more. Heat transfer oil is typically used for process temperatures up to 400 °C, molten Salt is typically utilized up to 550 °C.
