Nanocomposite plasma coatings for concentrated solar energy thermal conversion – NANOPLAST
Energy conversion is a sector whose development is strategic for our future. The objective of this collaborative project is to develop multifunctional nanocomposites coatings solutions with high performance for concentrated solar thermal conversion into electricity (CSP).
CSP technologies are currently in full development (up to 25% of the global electricity production forecast for 2050). Nevertheless, the solar fields of the CSP plants require an increase in their conversion efficiency and a lowering of costs because they represent, whatever the technologies, about 30% of the installation costs and 50% of the yield losses (mirrors, protections, absorbers). NANOPLAST project is focused on the development of high performance coatings for solar absorbers. One of the important points is the sustainability of the systems in function (# 25 years required). Aging studies of coated systems in order to predict their lifetime are therefore imperative, whereas they are almost non-existent at present.
In the NANOPLAST project, low environmental impact and commercially transferable plasma processes will be developed. Their versatility will make possible to achieve a wide range of composition and structuring 2D (multi-nanolayer) and 3D (inclusions at the nanoscale) of thin layers. The thermo-optical performance of nanocomposite structures (SiC / metal, TaON) will be evaluated by the consortium (4 laboratories and 1 industrial) recognized in the fields of CSP applications envisaged. The aim of this project is to meet the growing demand for nanocomposites on a European scale through an integrated understanding of the complete chain, from synthesis to performance evaluation.
Given the needs for the CSP, the objectives of the NanoPLaST project are:
- the development of multilayered multi-functional nanocomposite materials
- developed by high-density versatile plasma technologies with high transfer potential to industry
- with a high efficiency of solar thermal conversion via spectral selectivity
- with high durability: resistance to high temperature into air (500 <T <700 ° C) under conditions of solar applications and high resistance to thermomechanical stresses.
