Concentrated solar power generation

Generating power that is truly renewable, clean, and dispatchable bodes well for the future. Concentrated solar power (CSP) coupled with thermal storage can help secure future energy supplies as well as deliver fresh water and heat for other uses, such as large-scale food production. Alfa Laval offers state-of-the-art technologies that are key to the supply of solar power, freshwater and heat.

The solar future is looking bright

The sun is the Earth’s largest source of energy, yet it is still largely untapped for power production. International efforts are now underway for industrial-scale harvesting of solar energy. Several CSP plants, particularly in Spain, have been commissioned and have proven the viability of solar thermal power plants.

Installed at many of these CSP plants are Alfa Laval equipment, modules and systems, which contribute to generating solar thermal electricity.
