  1. 1. Power Generation From Solar Thermal Plants PREPARED BY :- TAUSIF ANWAR (100104135) SUMIT KUMAR JHA (100104129) VISHAL THAKUR (100104143) VISHU BANSAL (100104144)
  2. 2. What is STE ? An innovative technology for harnessing solar energy for thermal energy It is different from and much more efficient than photovoltaics, which converts solar energy directly into electricity
  3. 3. Classification of STE Solar thermal collectors are classified by the United States Energy Information Administration as: a. Low-Temperature collectors b. Medium-Temperature collectors c. High-Temperature collectors
  4. 4. Low-Temperature collectorsLow-Temperature collectors are flat platesgenerally used to heat swimming poolsThey can also be used in space heatingThey use air or water as the medium totransfer the heat to their destination
  5. 5. Medium-Temperature collectorsMedium-temperature collectors are alsousually flat plates but are used forheating water or air for residential andcommercial use. It consists ofSolar DryingCookingDistillation
  6. 6. High-Temperature collectorsHigh-temperature collectors concentratesunlight using mirrors or lenses and aregenerally used for electric powerproduction.It contains: System designs Parabolic trough designs Power tower designs Dish designs
  7. 7. Heat collection and exchange
  8. 8. Heat storage It allows a solar thermal plant to produce electricity at night and on overcast days. It allows the use of solar power for baseload generation as well as peak power generation. Heat is transferred to a thermal storage medium in an insulated reservoir during the day, and withdrawn for power generation at night .
  9. 9. Conversion rates from Solar Energy to Electrical Energy Solar dish/Stirling engine has the highest energy efficiency A single solar dish-Stirling engine produces as much as 25 kW of electricity, with a conversion efficiency of 31.25% Fresnel reflectors system has an efficiency of 19% Solar parabolic trough plants have been built with efficiencies of about 20%
  10. 10. Applications• The main use of this technology is in residential buildings where the demand for heating has a large impact on energy bills.• Commercial applications include car washes, military laundry facilities, eating establishments, drying, distillation and pasteurization.• The technology can also be used for space heating if the building is located off-grid or if utility power is subject to frequent outages.
  11. 11. • Solar water heating systems are most likely to be cost effective for facilities with water heating systems that are expensive to operate, or with operations that require large quantities of hot water.• Less expensive materials such as plastic or rubber can be used as heat collectors.• While solar collectors are most cost-effective in sunny, temperate areas, they can be cost effective virtually anywhere.
  12. 12. Advantages of Solar Thermal Energy No Fuel Cost Predictable,24/7 Power No Pollution and Global Warming Effects Using Existing Industrial Base
  13. 13. Disadvantages of Solar Thermal Energy High Costs Future Technology has a high probability of making CSP Obsolete Water Issue Ecological and Cultural Issues Limited Locations and Size Limitations Long Gestation Time Leading to Cost Overruns Financing
