TEXR:002 -53- ABSTRACT GENERATION OF ENERGY BY MEANS OF A WORKING FLUID, AND REGENERATION OF A WORKING FLUID A method of generating energy, which comprises expanding a gaseous working fluid from a charged high pressure level to a spent low pressure level to release energy, and regenerating the spent working fluid. The working fluid is regenerated by, in at least one regener- ation stage, condensing the working fluid in an absorption stage (A) by dissolving it in a solvent solution while cooling with a cooling medium, the solvent solution com- prising a solvent having an initial working fluid concen- tration which is sufficient to provide a solvent solution boiling range suitable for absorption of the working fluid; increasing the pressure of the solvent solution containing the dissolved working fluid by means of a pump (P) and evaporating the working fluid being regenerated by heating in an evaporation stage (E); withdrawing the evaporated working fluid for re-expansion to release energy; and recycling the balance of the solvent solution remaining after evaporation of the working fluid, to constitute the solvent solution for the absorption stage of that regeneration stage.
