Concentrated solar power PPT

3. INTRODUCTION:
 Concentrated Solar Power is a technology which
produces electricity by concentrating solar energy
in a single focal point.
 This concentrated energy is then used to heat up
a fluid , produce steam and activate turbines
that produce electricity.

4. TYPES :
The 3 main types of concentrating solar power systems are,
1. Linear concentrator,
2. Dish/engine &
3. Power tower systems.

5. 1. Linear concentrator
 Collects the sun's energy using long rectangular,
curved (U-shaped) mirrors.
 The reflected sunlight heats a fluid flowing through the tubes.
 The hot fluid then is used to boil water in a conventional
steam-turbine generator to produce electricity.
There are two major types of
linear concentrator Systems :
>> Parabolic trough systems and
>> Linear Fresnel reflector systems.

6. 2. Dish/engine
 Uses a mirrored dish similar to a very large satellite dish.
 The dish-shaped surface directs and concentrates sunlight onto a
thermal receiver, which absorbs and collects the heat and transfers
it to the engine generator.
 The most common type of heat engine used today in dish/engine
systems is the Stirling engine.
 The mechanical power is then used
to run a generator or alternator
to produce electricity.

7.  Uses a large field of flat, sun-tracking mirrors known as
heliostats to focus and concentrate sunlight onto a receiver
on the top of a tower.
 A heat-transfer fluid heated in the receiver
is used to generate steam.
 Some power towers use
The energy-storage capability,
or thermal storage, allows the system
to continue to dispatch electricity
during cloudy weather or at night.

9. ADVANTAGES :
 Simple and non-polluting.
 Potentially displaces the use of fossil fuel plants, that
emit the greenhouse gases that cause climate change.
 They prove to be efficient and cost-effective.
 Can be deployed relatively quickly and can contribute
substantially to reducing carbon dioxide emissions
 Provides emissions reductions compared to
natural gas counterpart.

10.  The desert regions of Australia and Africa.
 Mediterranean regions, with frequent sunshine.
 In INDIA, places like Gujarat & rajasthan etc..,
