Researchers from PROMES – CNRS, UPVD and LMAP – UPPA have demonstrated how graphene-based nanofluids can significantly enhance the performance of direct absorption solar collectors (DASC), while also revealing the complex stability challenges these fluids face under real operating conditions.
Using a parabolic trough pilot system, the team combined on-sun and off-sun experiments to evaluate both the optical and thermal behavior of graphene-water nanofluids. In controlled environments, the nanofluid maintained stable optical properties for over two and a half months, even when exposed to temperatures up to 80 °C. However, when used under real solar operating conditions in a closed-loop DASC, the nanofluid exhibited notable degradation in optical performance due to changes in pH linked to corrosion within the hydraulic circuit.
