A method of optimizing, within limits imposed by a heating medium from the surface of an ocean and a cooling medium from an ocean depth, the energy supply capability of a gaseous working fluid which is expanded from a charged high pressure level to a spent low pressure level to provide available energy, the method comprising expanding the gaseous working fluid to a spent low pressure level where the condensation temperature of the working fluid is below the minimum temperature of the cold water, and regenerating the spent working fluid by, in at least one regeneration stage, absorbing the working fluid being regenerated in an absorption stage by dissolving it in a solvent solution while cooling with the cold water, the solvent solution comprising a solvent having an initial working fluid concentration which is sufficient to provide a solution having a boiling point, after dissolving the working fluid being regenerated, which is above the minimum temperature of the cold water to permit effective absorption of the working fluid being regenerated, increasing the pressure and then evaporating the working fluid being regenerated by heating in an evaporation stage with the available hot water, feeding the evaporated working fluid and the solvent solution to a separator stage for separating the evaporated working fluid and the solvent solution, recovering the evaporated, separated working fluid, and recycling the balance of the solvent solution from the separator stage to constitute the solvent solution for the absorption stage; and an apparatus for carrying out the method.
