Concentrated solar power

Concentrated solar power systems use mirrors to focus sunlight and heat a fluid to produce steam that drives turbines to generate electricity. There are three main types: linear concentrators use curved mirrors to heat fluid in tubes; dish/engine systems use mirrored dishes to concentrate sunlight onto receivers connected to Stirling engines; and power tower systems use many heliostat mirrors to focus sunlight onto a receiver at the top of a tower to heat a fluid and produce steam. Concentrated solar power is advantageous because it is non-polluting, can displace fossil fuel plants, and is efficient and cost-effective to deploy relatively quickly to reduce carbon emissions compared to natural gas systems. Ideal places for concentrated solar power include desert regions of Australia and Africa

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.., IDEAL PLACES FOR CSP :
