Molten salts have recently received increased attention worldwide as key materials for sustainable and low-carbon energy supply technologies (e.g. thermal energy storage, concentrated solar power technologies, fission and fusion nuclear reactors) thanks to their appealing thermo-physical properties. In particular, they are used as fuel and coolant ...
In fast pyrolysis, the use of molten salts (i.e. eutectic mixtures) has shown potential for improving the heating rates of biomass, which is essential when targeting high bio-liquid yields. Techniques that allow faster screening of suitable eutectic salt mixtures for biomass pyrolysis before scaling up, are thus necessary. To validate a technique f...
The industrial sector is a major source of wealth, producing about one-quarter of the global gross product. However, industry is also a major emitter of CO2 and it represents a key challenge towards achieving the worldwide CO2 emission reduction targets. Nowadays, about 22 % of the overall energy demand is heating for the industrial sector, generat...
The current market searches for technologies allowing for efficient and sustainable production of biomass-based activated carbons for their further application in the adsorption of pollutants. Chemical activation of biomass in a bed of molten salts is a novel and promising technology in that regard. However, an in-depth understanding of the process...
Understanding molten salt chemistry is essential in ongoing research of the molten salt nuclear reactor (MSR). In this context, detailed understanding of the mechanisms underlying selective oxidation of metal species, such as Cr, is required to guide the design of effective corrosion mitigation strategies in molten salts. An important starting poin...
Ces travaux de thèse s'inscrivent dans le cadre de l'étude d'un procédé pyrochimique visant à décontaminer des résidus constitués d'une matrice de sels CaF2 contenant CaO en quantité significative et Pu sous diverses formes physico-chimiques (oxydes, fluorures, oxy-fluorures, ...). Ce procédé consiste à réaliser une extraction de Pu par réduction m...
Molten pyroprocessing salts can be used to dissolve used nuclear fuel from a reactor allowing recovery of the actinides. Previously, ANSTO have demonstrated hot isostatically pressed (HIPed) sodalite glass‐ceramic wasteforms for eutectic (Li,K)Cl salts containing fission products, but this system cannot be used for the analogous molten alkali fluor...

Molten salts are being used as heat transfer fluids and thermal energy storage materials for concentrated solar power (CSP) plants. It is imperative to choose the right Heat Transfer Fluids (HTF) and equally important to have accurate data on the properties of the same to help in the design of a new HTF. Determining the thermophysical properties of...
