Materials Challenges in Concentrated Solar Thermal Power Generation

Start time: 5.00pm AEST. Concentrated solar thermal power systems provide some unique materials, science challenges and thermal power generation. Efficiencies may be limited by material science considerations. Please join Materials Australia (Qld Branch) for this important talk on materials challenges in concentrated solar thermal power generation.
Solar Thermal Power


Join Materials Australia for a presentation by Dr.Stuart Bell on materials challenges in concentrated solar thermal power generation.

Concentrated Solar Thermal Power (CSP) generation presents several novel materials challenges. The thermal storage media and heat transfer fluids used (molten salts, sodium, and supercritical CO2) are mostly specific to CSP systems and not used in other power generation or industrial processing applications.

These fluids can cause surface and intergranular oxidation, selective de-alloying, carburisation/decarburisation, and liquid metal embrittlement of structural materials. Another defining characteristic of CSP is the high temperature and a thermal cycle which is inherent in the process. Temperatures from 600 - 800 °C, with at least one heat up-cool down cycle per day are expected at the receiver, piping and power block of the plant.

Such conditions are unique to CSP and push the boundaries of current materials durability knowledge. The ASTRI Advanced Materials group has been investigating materials interactions in CSP systems since 2014 and developing test capabilities for these challenging conditions. The aim of the work is to help de-risk the advancement of CSP in Australia by providing useful tools for design, service life prediction, condition monitoring, and operation and maintenance.


About the speaker:

Dr. Stuart Bell, Lecturer, School of Mechanical, Medical and Process Engineering, QUT
Stuart completed a Bachelor of Engineering (Mech) (Hons) at QUT in 2006 and a PhD in 2012. His Doctorate focused on photocatalytic water splitting, an area of chemistry and solar energy research which endeavours to use sunlight to produce hydrogen and oxygen from water. Stuart is currently a Lecturer in the School of Mechanical, Medical and Process Engineering in the Faculty of Engineering, where he teaches solid mechanics and conducts research in Concentrated Solar Thermal Power (CSP) with the Australian Solar Thermal Research Initiative (ASTRI). He researches materials compatibility under the challenging conditions experienced by Solar Thermal Power Generation. He has undertaken significant work in the area of molten salt corrosion which is a complex combination of chemistry, metallurgy and materials engineering.
