Abstract
The invention relates to a method for storage, in chemical form, of a quantity of mechanical or thermal energy, and for recovery, in mechanical form, of the energy stored; the invention also relates to devices for implementation of this method. The device comprises chambers for containing a non-ideal solution of a vapor and a liquid and chambers for containing liquified vapors separated from the non-ideal solution, these chambers being in close thermal contact, and whose volumes are connected by ducts to a motor for recovery of the stored energy during the recovery phase. Said motor can operate as a compressor for imparting the energy to be stored during the storage phase. The invention applies to the storage of any mechanical, electrical or thermal energy, and its recovery at the time of need.
