CONCENTRATED SOLAR POWER

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.

TYPES :

The 3 main types of concentrating solar power systems are,

1. Linear concentrator,

2. Dish/engine &

3. Power tower systems.

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.

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.

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.

3. Power tower systems 

WORKING 

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.

The desert regions of Australia and Africa.

Mediterranean regions, with frequent sunshine.

In INDIA, places like Gujarat & rajasthan etc..,
