IMDEA Energy Institute

IMDEA Energy Institute was created in 2006 as non-profit Foundation to promote and carry out R&D&i activities to contribute to the development of a sustainable and decarbonised energy system. IMDEA Energy is strongly committed to the transfer of R&D outcomes to the productive sector.

High temperature solar thermal technologies use concentrated sunlight to achieve temperatures between 300–2000ºC for application in thermal electricity generation, solar thermochemistry to produce fuels and commodities, or synthesis and surface treatment of materials. High concentration photovoltaic systems usually operate above 100 kW/m2. High flux solar simulators are designed to recreate the high radiation intensity distribution usually met in concentrating solar systems.
IMDEA Energy, Spanish research institute, working on sustainable energy, has a 42kWe high-flux solar simulator used for high-temperature solar thermal and thermochemical research. The installation consists of two independent rooms: a testing room, which accommodate the test benches, and the high-flux solar simulator room, respectively; and an external control table for the management and operation of the trial. The testing room is equipped with several gas lines, compressed air, single and three phase electric sockets, an independent air extraction system and internet connexion.


Compared with real solar concentrators, the high-flux solar simulators provide extremely controlled conditions and enable conducting indoor testing without any perturbation due to solar resource availability.
Flexible operation in terms of total power, heat flux distribution and working time makes this device particularly adapted to test materials, components and processes for commercial as well as research purposes.


Total available radiation power: 14 kW
Radiation peak flux 3.6 MW/m2
Maximum load: 250 kg

Readiness Level (TRL)

technology validated in relevant environment
"The centre is looking for commercial agreement; the partner sought should be a company active in developing new markets for solar fuels, daylighting, concentrating photovoltaics and concentrating solar power materials and components. Technical assistance from partner is required to establish the testing procedure and to validate the experimental results. The institute is also looking for research cooperation agreements with other research centres and companies to foster the technology basis of their research based on research projects or contracts."
(The pie chart refers to the entire portfolio contained in the database of the helpdesk)

Technology Readiness Levels (TRL) are a method of estimating technology maturity of Critical Technology Elements (CTE) of a program during the acquisition process. The use of TRLs enables consistent, uniform, discussions of technical maturity across different types of technology.
