Concentrated Solar Power (CSP) is a renewable energy technology that harnesses sunlight to generate electricity through concentrated heat. Unlike photovoltaic solar panels, CSP systems use mirrors or lenses to focus sunlight onto a small area, producing high temperatures that drive turbines. This presentation explores the principles, technologies, benefits, and challenges of CSP, highlighting its role in sustainable energy production and its potential to contribute to a cleaner energy future.
Principles of CSP
CSP systems concentrate sunlight to produce high temperatures
Heat is transferred to a working fluid, typically water or molten salt
The heated fluid generates steam to drive turbines and produce electricity
Energy can be stored for use during cloudy periods or at night
Types of CSP Technologies
Parabolic trough systems use curved mirrors to focus sunlight along a line
Solar power towers use a field of mirrors to concentrate light on a central receiver
Dish Stirling systems use parabolic dishes to focus sunlight onto a Stirling engine
Linear Fresnel reflectors use flat mirrors to concentrate sunlight onto a linear receiver
Key Components of CSP Systems
Mirrors or lenses to concentrate sunlight
Receiver to absorb and transfer heat
Heat transfer fluid to carry thermal energy
Storage system to retain energy for later use
Power block to convert thermal energy into electricity
