Développement de coulis à changement de phase eau-dans-huile pour le transport frigorifique et le stockage en dessous de 0 °C. 

Development of water-in-oil phase change slurries for cold transport and storage below 0 °C.

Numéro : 0014



Thermal energy storage is a key factor in sustainability of energy systems that enable a supply-demand shift. A Water-in-oil (W/O) phase change slurry (PCS) for cold storage and transport below 0 °C was developed in this study. The freezing point was adjusted to the desired application temperatures of up to -25 °C. It was addressed by dissolving additives in the aqueous phase with low chaotropic impact to retain the slurry stability. The PCS was produced by ultrasonication and the stability of different oils and surfactants with water was screened. The thermal properties were characterized by DSC and the mechanical stability was assessed with a rheometer. Combinations of alkanes, polysorbate surfactants, and water were found to be stable for 100 thermal cycles. Their initial supercooling of 17 K was decreased by the additives as well by up to 10.9 K, making these PCS an efficient cold transport and storage liquid at low temperatures with higher thermal capacity as compared to pure oil storages.
