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)
