Thermal stability and durability of solar salt-based nanofluids in concentrated solar power thermal energy storage: An approach from the effect of diverse metal alloys corrosion


Publication Highlights

  1. Solar salt nanofluids are characterized before and after a 90-day, 500°C corrosion test with 304H, 306L, AISI 1045, Inconel.
  2. The degradation, thermal stability, and durability of molten salt nanofluids under working conditions as TES materials for CSP plants are evaluated.
  3. Effect of corrosion products precipitated during the corrosion test on the physical and thermal properties of nanofluids.
  4. 316L stainless steel shows better performance in contact with solar salt-based nanofluids as a TES tank material.
  5. Nanofluids are presented as suitable for TES applications with stable and improved thermophysical properties in-service.
