CSPonD: Concentrated Solar Power on Demand


Problem: Alternative energy storage; Elimination of solar tower; Significant thermal energy loss of conventional solar boilers; High capital costs in building heavy solar boilers Technology: The system is designed to absorb concentrated solar radiation in a molten eutectic salt. The liquid salt is contained in an insulated crucible with an aperture for entry of concentrated light. The salt serves as a volumetric energy absorber an energy storage medium a high temperature heat transfer fluid and a suspending fluid for absorptive nanoparticles. The system efficiently absorbs solar radiation through the volume of molten salt and retains the energy for gradual release into a heat exchange system. The typical operating temperature of the device is 600。C to 1000。C. The device can be combined with solar collection apparatus and heat exchanging mechanisms.


1) Increase of 30-40% in efficiency over current technologies 2) Energy Storage 3) Low capital costs
