Abstract (en)

[origin: EP2447479A1] The invention concerns a method for cooling a carrier fluid (5), which carrier fluid (5) is used to drive a turbine (29) in an electric power plant (2'). According to a first embodiment of the invention at least part of a cooling process is realized by leading the carrier fluid (5) and/or a cooling fluid (13, 46) for cooling the carrier fluid (5) underground a soil to a depth (41) in which the soil is substantially cooler than the ambient air. According to a second embodiment of the invention at least part of a cooling process is realized by supplying at least some of the carrier fluid (5), and/or at least some of a cooling fluid (13) used to cool the carrier fluid (5), from a cold storage (51) which stores fluid at a significantly lower temperature than the temperature of the carrier fluid (5) in the turbine (29). The invention also concerns electric power plants (2') and a cooling system (4) operating according to the embodiments of these methods.
