Method for storing a coolant fluid comprising two phases of one and the same substance in melting equilibrium, according to which an enclosure for storing said fluid is used in which the coolant fluid stored settles into a lower liquid layer and an upper solid layer, the coolant fluid to be stored is introduced into the enclosure at the level of the lower layer, and the coolant fluid to be removed from storage is extracted from the enclosure at the level of the upper layer, wherein, in combination, on the one hand, a gaseous headspace is set up between the upper layer and the upper wall of the enclosure and, on the other hand, the coolant fluid to be removed from storage is extracted, from a withdrawal zone located at the level of the interface between the upper layer and the gaseous headspace, through a vertical flow by generating a vortex.
