Alfa Laval - Concentrated solar power generation

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. 

Alfa Laval solutions for CSP plants

Thermal storage:

  • Ultra compact oil/salt heat exchangers

Steam processes:

Auxiliary cooling:

  • Wet surface air coolers using dirty water streams, such as blow down from reverse osmosis, cooling tower or steam loop, and wastewater from local municipalities
  • Hybrid cooling solutions when coupled to Alfa Laval Dry Coolers

Solar desalination:

Power block utilities:

  • Oil coolers, oil treatment skids, auxiliary boilers

Wastewater treatment:

  • Decanters and heat exchangers
