This review summarizes past research and future strategies for the improvement of pair heat transfer fluids (HTF) - containing material, used in concentrated solar power (CSP) plants, focusing on most interesting promising HTF, chloride molten salts. Indeed, their low cost operating range temperature make them very strong potential candidates CSP furthermore improvable by wisely adding nanoparticles. Nevertheless, well-known aggressive behaviour entails selecting a long-lasting resistant...
MgCl2/NaCl/KCl salt appeared as a high-potential heat transfer fluid for concentrated solar application, offering wide operating range and low cost. Nevertheless, MgCl2 hydrates atmosphere relative humidity are the limiting factors real scale CSP plant, leading to severe corrosion. Thus, Inconel 617 was tested at 700ºC up 24 h in air simulate punctual failure inertization system of plant. XRD SEM-EDX analysis showed unstable multilayers growing cascade, highlighting chromium, aluminum,...
Molten salts as heat transfer fluids (HTF) for concentrated solar power (CSP) plant application are considered the best thermal storage medium, and more precisely molten chlorides, presenting a wide operating range coupled with competitive cost. Furthermore, MgCl2-NaCl-KCl (MgNaK) mixture appeared most promising one but need further studies to better understand its thermophysical properties. Indeed, hydrated form leads formation of corrosive compounds. In this research, two different methods...
The performance of a concentrated solar power plant is strongly driven by its heat storage capacity and evolving through the development new salt mixtures. Molten nitrates, which have already proved their high potential, can be further improved in terms economic environmental aspects, with mitigation toxic compounds higher electricity generation capability. In this work, stability range energy density characterisations were performed on nitrate ‘Solar’ salt, along life cycle assessment,...
Abstract Several authors have shown promising results using Ti and Mg to develop materials that combine the benefits of these two metals, such as their low density absence harmful second phases, which makes them attractive for aerospace biomedical applications well hydrogen storage. However, titanium magnesium are almost immiscible there great differences in processing temperatures metals. Within techniques reported literature obtaining Ti-Mg alloys, powder metallurgy high-energy ball...
Concentrated solar power plants present several issues due to salt-induced corrosion, and the modelling of these mechanisms is needed for estimating lifetime predictions. Moreover, a small variation temperature can lead microstructure changes allotropic transformations thus free energy formation phases within materials. Therefore, corrosion study molten carbonates, being high potential heat transfer fluids CSP applications, on H230 alloy was performed at 700ºC, 750ºC 800ºC up 1000 h, in air...
