The energy department provides access to researchers and industry in the field of CST to its world-class facilities through dedicated programmes provided via EU-wide projects such as SFERA-III and StoRIES. The access is fully or partially funded by these projects, and are arranged via an application process. The services offered range from solar resource assessments, services on reflectors and concentrators, on Heat Transfer Fluids, on Energy Storage etc.

The Energy Department offers external access through the SFERA-III access gateway to the following facilities (name of service in bold)

The PROTEAS field facility for experiments and tests in:

  • Corrosion testing of solar reflectors in challenging coastal condition in a semi-arid island environment (exposure)
  • Testing of components in a fully equipped and instruments molten salt loop with continuous monitoring, controlling, and recording of a Molten Salt Loop (Msloop)
  • Testing and characterization of new innovative solar receivers (Receiver)
  • The MED (Multiple Effect Distillation) Desalination facility for tests in characterization of solar powered thermal desalination methods for sea water desalination using innovative heat exchangers and processes (MED).

The FRESNEL facility for experiments in

  • Outdoor optical and thermal performance of Linear Fresnel receivers and (Fresnel)
  • Linear Fresnel control algorithms (Fresnel)

The ATHLab (Athalassa Heliostat Testing Facility) for testing control of tracking algorithms for heliostats (ATHLab)
