Workshop on ‘Very high temperature accelerated ageing of flat ceramic specimens (solar receivers) under concentrated solar radiation’


Concentrated solar power (CSP) is an important building block in installing a secure, competitive and sustainable energy system.

Today, the diverse solar thermal energy solutions commercially available differ with respect to concentration technology, receiver type and shape, nature of the heat transfer fluid (HTF) and capability to store thermal energy, to turn it later into process heat or electricity on demand.

However, more cost-effective solutions are required for a wider-scale deployment of the CSP technology.

Novel functional materials and material combinations throughout the manufacturing chain are therefore needed to enhance the efficiency of solar energy harvesting beyond that of the current state-of-the-art technologies.


Advanced materials solutions for NEXTgeneration high efficiency concentrated solar power (CSP) TOWER systems (NEXTOWER) project is a four year research project funded by the European Commission which aims at demonstrating high-performance durable materials for the next generation of concentrated solar power (CSP) air-based tower systems, making them commercially competitive in the energy market beyond 2020.


The kick-off meeting was held in Almería (Spain) on 4 March 2020.


A draft CWA '‘Very high temperature accelerated ageing of flat ceramic specimens (solar receivers) under concentrated solar radiation’' has been developed and is now available for commenting.

You are kindly invited to submit comments on the draft CWA to the WS secretary Ms Ana Mariblanca Sanchez (, using the below commenting form.

Deadline: 12 February 2021.
