CSPonD: Concentrated Solar Power on Demand

Technology:

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.

Benefits:

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