CSPonD: Concentrated Solar Power on Demand
Keywords:
Solar mirror, Binary actuation, Active optics, TrSolar thermal power, Energy storage, Ternary eutectic salt, Nanoparticles, Salt bath, Nitrate, Chloride and Carbonateacking
Applications:
Solar thermal power generators
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.
Advantages:
- Increase of 30-40% in efficiency over current technologies
- Energy Storage
- Low capital costs
