Solar Power on Demand: Making Energy Available 24/7

The direct evaporation effect of the sun’s heat uses water as the transfer medium. It flows through receiver tubes, onto which the sunlight is concentrated by means of parabolic mirrors. The sun heats the water up to create superhot steam. Steam turbines and generators turn the energy captured in that steam into electricity. To make solar power available at night, theenergy from the superheated steam is collected in several heat storage systems. First, molten salt is used to store the sensible heat via heat exchangers (hot tank). Then the latent heat store,connected to a storage buffer, captures the evaporation heat (intermediate tank). The molten salt which is not charged with heat is stored in the cold tank. (Picture: Linde) arrow back Image Zoom
