Les centrales solaires thermodynamiques

Abstract

Thermodynamic solar plants transform the energy radiated by the sun into heat and then convert this heat into a mechanical and electrical energy via an electrical generator. A reduction of the production cost by least 50% must be envisaged for 2015 so that these technologies can compete with the conventional fossil, nuclear or hydraulic technologies. This objective requires an improvement in the performance gain and thus specific works on the concentrators, receivers and storage devices. This article presents the technologies implemented in the solar plants as well as the criteria of selection and dimensioning for their essential components.
