Pilot-scale system with particle-based heat transfer fluids for concentrated solar power applications
Bonino, C. A., Hlebak, J., Baldasaro, N., & Gilmore, D. (2020). Pilot-scale system with particle-based heat transfer fluids for concentrated solar power applications. In Proceedings of the ASME Power Conference Article POWER2020-16588, V001T08A014 American Society of Mechanical Engineers(ASME). https://doi.org/10.1115/power2020-16588
Concentrated solar power (CSP) is a promising large-scale, renewable power generation and energy storage technology, yet limited by the material properties of the heat transfer fluid. Current CSP plants use molten salts, which degrade above 600°C and freeze below 220°C. A dry, particle-based heat transfer fluid (pHTF) can operate up to and above 1,000°C, enabling high-efficiency power cycles, which may enhance CSP’s commercial competitiveness. Demonstration of the flow and heat-transfer performance of the pHTF in a scalable process is thereby critical to assess the feasibility for this technology.
