Koncentrerad solenergi

Solenergi är i ordets rätta bemärkelse förnybar, ren och reglerbar och bådar gott för framtiden. Koncentrerad solenergi (CSP) kopplad till termisk lagring kan bidra till att säkra den framtida energitillgången och leverera färskvatten och värme för andra ändamål som t.ex. storskalig livsmedelsproduktion. Alfa Laval erbjuder toppmoderna tekniker som är nyckeln för att leverera solenergi, färskvatten och värme.

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:

  • Turbine condensers
  • Feedwater pre-heaters

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:

  • Multi-effect plate evaporators producing quality boiler feed water

Power block utilities:

  • Oil coolers, oil treatment skids, auxiliary boilers

Wastewater treatment:

  • Decanters and heat exchangers


  • Most advanced thermal storage solutions on the market
  • From water-use minimization to water making
  • Comprehensive water management for arid areas
  • Remote towns can get their power and their water from a local CSP plant
