METHOD FOR MODIFYING A SOLAR THERMAL POWER PLANT OPERATING ON CONVENTIONAL OIL BASED TECHNOLOGY INTO A HYBRID SOLAR THERMAL POWER PLANT AND SUCH A HYBRID SOLAR THERMAL POWER PLANT

摘要

Method for modifying a solar thermal power plant (2) operating on conventional oil based technology into a hybrid solar thermal power plant (1), wherein the method comprises: • providing an oil based solar thermal power plant (2) comprising a solar collection system with at least one radiation absorber tube containing a heat transfer oil to be heated by means of the solar collection system, • providing an molten salts solar thermal power plant, (4) wherein the molten salts solar thermal power plant comprises a solar collection system to heat a molten salts mixture • coupling of the respective plants such that the hybrid solar thermal power plant is configured to heat medium temperature steam that is generated by the oil based solar power plant by means of the molten salts mixture thereby producing high temperature steam and subsequently supplying it to a steam turbine (40) to generate electricity.
