Concentrated solar power (CSP) is a technology that generates electricity by concentrating solar energy, which heats a fluid to produce steam and activate turbines. The main types of CSP systems include linear concentrators, dish/engine systems, and power towers, each with distinct mechanisms for capturing and converting solar energy. Although CSP has several advantages, such as being non-polluting and efficient, it also faces challenges like intermittency, high costs, and location dependency.

- 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. 3
- 4. TYPES The 3 main types of concentrating solar power systems are: Linear Concentrator Dish / Engine Power Tower Systems 4
- 5. 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. 5 There are two major types of linear concentrator Systems : Parabolic trough systems Linear Fresnel reflector systems
- 6. 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. 6
- 7. POWERTOWER SYSTEMS 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. 7
- 8. PROS & CONS PROS • 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. CONS • Intermittent. • Low energy density. • Construction/installation costs are high. • They require a considerable amount of space. • Manufacturing processes often create pollution. • Heavily location dependent. • Will involve significant transmission distances/losses. 8
