IV. Concentrating Solar Power (CSP): A Bright Future for Large-Scale Solar Energy Generation
Explanation of CSP and How It Works:
Concentrating Solar Power (CSP) is a technology that utilizes mirrors or lenses to focus sunlight onto a small area, typically a receiver. This concentrated sunlight heats a fluid, which is then used to generate steam. The steam drives a turbine connected to a generator, producing electricity.
CSP differs from traditional photovoltaic solar technology in that it uses thermal energy rather than directly converting sunlight into electricity. This enables the system to store energy for use during non-sunny hours.
Highlighting the World’s Largest CSP Plant in UAE:
In 2023, a significant milestone was reached with the commencement of commercial operation at the Mohammed bin Rashid Al Maktoum Solar Park in the United Arab Emirates. This park, with its enormous scale and advanced technology, has set a benchmark for CSP plants worldwide.
