This document discusses solar power generation using molten salt technology. It introduces molten salt technology, how it functions in a solar power system, and its advantages over other energy storage methods. Molten salt uses a mixture of salts that can reach high temperatures and is a low-cost medium for storing solar energy even after sunset. Implementing molten salt solar plants in India would help reduce dependence on coal and lower costs for the electric sector by providing renewable energy storage.

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.

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.

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.

8. COMPARE TO OTHER
OTHER 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.

10. COMPARE TO OTHER
COST 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).

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.

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. 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.
