solar power by molten salt technology

  1. 1. SOLAR POWER GENERATION BY MOLTEN SALT TECHNOLOGY BYK.MADHU SUDHAN C.RAJESH 09X51A0220 09X51AO239 III-B.TECH III-B.TECH EEE EEE MADHU & RAJESH
  2. 2. AGENDA INTRODUCTION WHAT IS MOLTEN SALT TECHNOLOGY? FUNCTIONAL MODEL OF MOLTEN SALT SYSTEM COMPARE TO OTHER SOURCES WHY WE GO FOR THIS TECHNOLOGY? ECO-FRIENDLY NATURE IMPLEMENTATION IN INDIA CONCLUSION MADHU & RAJESH
  3. 3. INTRODUCTION Energy is major input for overall socio-economic development of any society. Coal,gas and oil will not be three kings of the world forever. So we develop renewable sources as replacement, at present Solar energy is the fast growing renewable. Molten salt technology based solar plant is better replacement . This Technology is cheaper,economical and eco-friendly compare to all other. MADHU & RAJESH
  4. 4. WHAT IS MOLTEN SALT ? Molten salt generally Refers Melted salt. This fluid(salt-water) have good heat capacity. We can attain red heat (>801°c ). Easy phase chngining capability. Mixture of sodium nitrate and potassium nitrate presently used as molten salt in commercial plants. MADHU & RAJESH
  5. 5. FUNCTIONAL MODEL MADHU & RAJESH
  6. 6. MOLTEN SALT SYSTEM MADHU & RAJESH
  7. 7. MOLTEN SALT SYSTEM Mixture of nitrate salts heated in tubes up to 565°c Returns to hot storage tank. Hot salt fluid pumped for generating purposes. The salt at 265°c returns to cold storage tanks used in Rankin cycle again. Tubes in receiver designed to Absorbs 95% of the incidence of sun light. Total molten salt loop designed <2500 feet which is heat traced to prevent freezing. MADHU & RAJESH
  8. 8. COMPARE TO OTHEROTHER STORAGE MEDIUMS: Stone is lot cheaper, but ability to store the heat is less. Graphite and ceramic are more expensive mediums. PV panels are presently used in commercial plants are relatively high cost. Using of PV panels increases capital cost of plant. For those reasons we adopt molten salt system. MADHU & RAJESH
  9. 9. COMPARE TO OTHER ENERGY STORAGE & OUTPUT IN THE DAY OF MOLTEN SALT SYSTEM MADHU & RAJESH
  10. 10. COMPARE TO OTHERCOST AND ECONOMICAL BASIS: Primary advantage of this system is we can attain 98% of thermal efficiency. For identical scale generation(800MWht)will cost around US$44/KWht. This is cheap compare to all other Storage Mediums. The latest progress in this systems is we can capture 1MWht of thermal energy(largest). MADHU & RAJESH
  11. 11. ECO-FRIENDLY NATURE Molten salt is non-toxic, non-flammable energy storage medium. We can reduce atmospheric CO2 Emissions by more 30,000 tons for 110GWH/year power generation. We can also increase plant efficiency 1.5 to 3 times compare to other renewable Eco-friendly. Gema solar plant in Spain is the first commercial plant using this technology. MADHU & RAJESH
  12. 12. IMPLEMENTATION IN INDIA SOLAR RESOURCE MAP IN INDIA MADHU & RAJESH
  13. 13. IMPLEMENTATION IN INDIA Presently India gets 65% Of it’s energy from thermal plants and <1% from solar energy. Day to day increasing cost of coal it is burden to the electric sector. With the use of this technology in solar plants burden on electric sector should be reduced. Main problem in India is Governments are lack of interest to develop this type of alternatives. MADHU & RAJESH
  14. 14. CONCLUSION As our demand for electrical power grows, it becomes increasingly urgent to find new alternatives. In the past, the limiting factors of renewable energy have been the storage and transport of that energy. In spite of above advantages molten salt based solar plants are better alternative at present.
