A method of recovering energy resulting from the change of state of the dry ice, this method being implemented by means of a device (1) comprising: - an enclosure (2) containing dry ice at a sub-pressure atmospheric and at a solidification temperature corresponding to the sub-atmospheric pressure; - A primary circuit (3) for energy recovery through the chamber (2) and in which circulates a heat transfer fluid; the method comprising the following steps: - passage of the heat transfer fluid in the primary circuit (3), this step causing the heating of the dry ice and its change of state to CO2 and the cooling of the heat transfer fluid; extraction of the CO2 contained in the chamber (2); wherein the process comprises a step of substantially continuously depressing the enclosure (2) at a sub-atmospheric pressure.
