Concentrated Solar Power (CSP) consists of the concentration and the use of solar energy in a thermodynamic cycle to produce electricity via a turbine. Compared to other technologies, CSP is grid friendly and dispatchable thanks mainly to its efficient and cost effective energy storage. However, in order to produce a competitive kilowatt-hour, CSP technology still faces some challenges.
Durability of the solar field components in a CSP plant is one of the issues that R&D efforts are undertaking in many research institutions worldwide. In order for such plants to operate fully for more than 20+ years, the ageing phenomena of plant components such as mirrors need to be understood and their lifetime to be improved. Actually there is no model to describe ageing mirrors related to the environmental stress despite the fact that this information is needed to better define standards of accelerate tests used to qualify the durability of these components. This point constitutes the scope of this thesis.
The Moroccan Agency of Sustainable Energy, Masen, has recently initiated an R&D collaboration program with CEA, the French Institute for Atomic and Alternative Energies. The idea behind such a partnership is the implementation of a joint lab dedicated to advanced studies and research on durability issues of solar components, systems and subsystems. This joint lab is deployed both on Ouarzazate R&D platform and CEA/Liten R&D at National Institute of Solar Energy (INES). The objective of this thesis is to carry out accelerated aging tests of solar mirrors and absorbers. These tests will allow degradation phenomena acceleration and tests time saving. The main tasks of this work concern the design, the conception and the realization of experimental equipment’s which can be used to study the ageing phenomenon. The R&D platform of NOOR project offers high irradiation and ideal tools to conduct these accelerated tests.
Research Activities and Tasks:
To carry out such research, Masen is looking for PhD candidates willing to tackle those R&D challenges. Research activities include but are not limited to:
Review and analysis of literature on accelerated ageing “sous flux” , with focus on CSP power plants conditions and components
Design and realization of experimental setups to carry out accelerated tests of solar components (mirrors and absorbers mainly)
Implementation of qualification tools and control of test parameters: flow homogeneity, temperature and measurements instrumentation
Carrying out real-like-condition testing campaigns
Analysis of experimental results (samples degradation) to identify ageing parameters and its kinetics in relation with tests conditions. Correlation between climatic and accelerated tests conditions. Determination of representative tests parameters of reel conditions of CSP plant
Elaboration of accelerated ageing tests protocols that could be used to establish new standards in this field.
Contribution to modeling approaches to help explaining of components’ ageing
Scientific communication on results and research perspectives
The PhD program is financed by Masen and will take place mainly within the R&D Platform of
Ouarzazate, Morocco, with some regular stays in Rabat (Morocco) for training or experiments. The
candidate may also have to travel to Chambery (France) if needed.
Successful candidates should demonstrate high level academia records as well as strong motivations
and abilities to work in international and collaborative R&D projects. They should fulfill also the
Holding or in final year of Master’s/Engineering Degree in Physics, Instrumentation, Material
