Launch of the 4th SFERA-III transnational access campaign

With SFERA-III, benefit from free access to top research infrastructures in Concentrated Solar Thermal power across Europe!

The 4th SFERA-III access campaign has been launched on 1st November 2021. This call for projects provides free access to 43 installations of 14 state-of-art research infrastructures in Concentrated Solar Thermal power in 8 countries:


  • The Cyprus Institute: FRESNEL, ATHLab (Athalassa’s Heliostat Testing Laboratory), Exposure, Msloop, Receiver and MED


  • CEA – ESTHER: LHASSA (Latent Heat Storage with PCM)
  • CEA – DURASOL: Opti-Lab and Indoor


  • DLR: Synlight (High-flux solar simulator)
  • Fraunhofer ISE: WT Lab, TES-LAb, CD-Lab (Durability testing of materials for concentrated solar thermal), C-Lab Field and CD-Lab


  • ENEA: ESOL (ENEA Solar Collector Optics laboratory), TFC-LAB, OMSoP and PCS


  • University of Evora: CER (Renewable Energies Chair), PECS (Solar Concentrators Testing Platform), INIESC (National Research Infrastructure in Solar Energy Concentration) and DNI-N
  • LNEG: H2, HPC and LMR-LES


  • PSA-CIEMAT: SOLFU, DESAL, MOSA (Molten Salt Test Loop for Thermal Energy Systems), HIWATOX and SOLWATER
  • IMDEA: HTPU-CDL (Computational Design Lab for High Temperature Processes), HTPU-LAB, KIRAN42 (42kWe High Flux Solar Simulator) and VHCST (Very High Concentration Solar Tower)


  • ETH Zurich: HFSS (High flux solar simulator) and CHEM (Chemical Laboratory)


  • METU/ODAK: GunSolSim (High flux solar simulator)

The campaign offers access to a wide spectrum of experiments such as:

  • Solar thermal electricity generation
  • Solar fuels production
  • Cycles for chemical storage of solar energy
  • Solar water treatment
  • Solar heating and cooling of buildings to improve energy efficiency
  • Modelling and controlling of concentrating solar technologies for power plants and for industrial processes
  • High value material synthesis and/or coatings deposits
  • High-flux photochemistry and photo-physics
  • Characterisation of materials behaviour and properties under extreme conditions

The 4th SFERA-III campaign is open until 31 January 2022. The selected projects will benefit from 1 to 4 weeks of free access to the chosen facilities for a team of up to 2 persons. Moreover, travel, accommodation, and subsistence costs are reimbursed by the project’s budget.
