AB The cost-effective optimisation of renewable power generation systems is a must in the present context of a global climate crisis and a growing demand for reliable, affordable and clean power supply. Reliability is a challenging issue for renewable technologies like photovoltaics, which produces electricity under ceaseless solar irradiation and therefore suffers of daily intermittency. The integration of concentrated solar power plants in hybrid power blocks has been proposed as a solution for this intermittency by taking advantage of thermal energy storage to maintain production and compensate the supply. A limitation for this solution is the low solar-to-thermal energy conversion due to the poor thermophysical properties of the typical heat transfer fluid flowing through solar collectors. The use of nanofluids as has been proposed to improve this conversion.This thesis aims to provide knowledge and understanding of the Physical Chemistry of nanofluids, with particular attention to features and processes that determine their stability and heat transfer and storage capabilities. Here Pd nanoplate-containing aromatic oil-based nanofluids have been prepared and characterised through different techniques to assess their applicability as volumetric absorbers and heat transfer fluids in parabolic trough collectors of concentrating solar power plants. A significant contribution from this thesis refers to the influence of the structure and dynamics of solid-liquid interfaces on the physical properties of nanofluids on the basis of simulations at the density functional theory and molecular dynamics levels-of-theory. The findings presented are expected to have both practical and fundamental implications on future research.
