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.
