SOLAR THERMAL

group

� CSP converts solar radiation into high temperature heat using various

mirrors/reflectors and receiver configuration.

� Channeled through conventional generator Plant consisting

� Solar Field : Collects solar energy and converts it into heat

� Power Block :Converts heat energy to electricity

� The basic Subsystems are

� Collector

� Receiver

� Transport/Storage

� Conversion

� CSP Technologies

� Parabolic trough

� Power Tower

� Parabolic Dishes

SOLAR THERMAL -CSP

group

PARABOLIC TROUGH

� Parabolic Trough shaped mirrors

concentrate solar radiation to thermally

efficient receiver tubes placed in trough

focal line

� Thermal transfer fluid is circulating in tubes

� Heated to approximately 400 o C this fluid

pumped through series of heat exchangers

to produce superheated steam

� Steam heat converted into electricity by

conventional steam turbine generator

� Operating temperature ~350-400 0 C

� Plant Efficiency 14 %

� Best Land use Factor

group

SOLAR TOWER

� Circular array of heliostats concentrate

sunlight onto a central receiver mounted

on top of the tower

� Heat transfer medium in tower converts

concentrated radiation into thermal

energy

� Superheated steam for turbine operation

generated from this thermal energy

� Heat transfer medium include Water,

Liquid sodium, molten salts etc.

� Operating Temperature ~ 550-600 o C

� High Conversion Efficiency

� Storage at high temperature

group

PARABOLIC DISHES

� Parabolic dish shaped reflector

concentrate radiation to receiver

located at its focal point

� Receiver absorbs this radiation to

heat the fluid

� This fluid is used to generate

electricity in small piston or sterling

engine or micro turbine attached to

the receiver

� Operating temparature~750 o C

� Very high Conversion Efficiency

COST OF SOLAR PLANT - CSPCase Study of 50 MW CSP Plant

group

� 1 Sq. Km of concentrated radiation is sufficient to generate 100-120 GW

(Equivalent of Annual Production of a 50 MW Conventional Plant)

� Each Sq. m of solar reflector avoids annual production of 250 –300 kg

of CO2

� Future of Solar Thermal (Greenpeace & ESTIA Scenario 2025)

� Annual Capital Investment in Solar Thermal From $ 60 million in 2006 to $ 16.4 Billion in 2025

� Expansion will create about 50,000 jobs

� Up to 2025 emission into the atmosphere avoided 395 Million tons of CO2

� Annual emission avoidance in 2025 57.5 Million tons of CO2

� By 2030 100,000 MW

� By 2040 600,000 MW

(5% of world electricity demand)
