SolAir

The SolAir research project addresses a technology development for cost reduction and further commercialization of Concentrated-Solar-Power (CSP) tower plants.

It was the objective of this project to develop and demonstrate a new air Volumetric-Receiver technology based on the HitRec project results. Which was Silicon Carbide ceramic VR-units resulting in improved reliability and performance with reduced component costs for better performing solar tower power plants. A prerequisite of the economic success of the air Volumetric-Receiver technology was to qualify the innovative receiver design and the used ceramic materials in an experimental receiver unit (200 kWth – SolAir200). And, after that demonstrate the technology in a scale-up test receiver system (3 MWth – SolAir3000) on the 90 meter high CESA tower at Plataforma Solar de Almeria in south of Spain.

The key ceramic SolAir VR-units mounted next to each other to receive all the concentrated solar power. The square shaped ceramic Volumetric Receiver Units (VR-units) 140×40 mm across are developed by Stobbe Tech A/S and in large numbers manufactured by SGIK GmbH from Silicon metal infiltrated Silicon Carbide extruded honeycomb ceramics and cast Silicon metal infiltrated Silicon Carbide cups.

The European partners cover all the sectors involved in the R&D of the advanced air Volumetric-Receiver project and composed by:

  • Abengoa / INABENSA, the Spanish industrial partner – hidrogeno.abengoa.com
  • DLR, Germany with scientific capabilities in the field of solar thermal concentrating technologies with special knowledge of R&D of air Volumetric-Receiver – dlr.de
  • Ciemat including availability of Europa’s largest solar test beds on the ”Plataforma Solar de Almeria” in South-Spain – ciemat.eswww.psa.es
  • CERTH / CPERI, Greece with scientific capabilities in the field of material science – apt.cperi.certh.gr
  • IBERESE, Spain performing cycle optimization of the (CSP) tower plants
  • Stobbe Tech, Denmark for the development, manufacturing and supply of special ceramic VR-units for the air Volumetric-Receiver – stobbe.com

Title: “Advanced solar volumetric air receiver for commercial solar tower power plants”

The project was sponsored by the EU commission under FP5 – “Energy, Environment and sustainable development” with the EU scientific officer Dr. Philippe Schild.
