As Next-CSP will end in July 2020, we have published a new video which presents the impacts, challenges and success of the project. The takes were made at the Themis solar tower (France) with a testimony of Gilles Flamant (CNRS-PROMES), Next-CSP coordinator.
Watch the video just below:
Next-CSP is a European funded project, started in 2016 and gathering 10 European partners. The aim is to demonstrate a 3MW fluidized particle-in-tube receiver in a solar tower using concentrated solar power. The technology behind is to use high temperature particles as heat transfer fluid, up to 750 degrees for higher efficiency, and also as storage medium for better dispatchability when electricity is needed.
Testimony by Gilles Flamant (CNRS-PROMES), Next-CSP coordinator:
What are the expected impacts of Next-CSP?
The increase of the efficiency of the system, about 15 to 20 %, for the conversion efficiency but also to improve the capacity of the system to be integrated in the network using high-capacity heat storage.
What are the most challenging aspects?
The first one is the temperature of the tubes of the receiver because we are working for the tube at 950 which is the limit of the metals. Also, the second challenge is related to the – let’s say – the circulation of particles because particles are not like a liquid exactly.
What success has been achieved so far?
To be able to implement all the system now at the top of the tower. We are now starting the experiment filling the particles inside. It is a real success because now we will start to test the system with the sun.
