Next-CSP is a consortium of 10 partners gathered to fulfil one objective: improving the reliability and performance of Concentrated Solar Power (CSP) plants through the development and integration of a new technology based on the use of high temperature (800°C) particles as heat transfer fluid and storage medium. To achieve this objective, the project will demonstrate the technology in a relevant environment (TRL5) and at a significant size (4 MWth). The complete system will be tested at “Thémis” experimental solar tower facility (France).
