The High Temperature Processes Unit at IMDEA Energy promotes the decarbonisation of the energy system through the use of solar energy in the synthesis of fuels and chemical heat production in industrial processes, and electricity generation. To this end, we focus on research and development in modular, efficient, dispatchable and economically competitive concentrating solar technologies.

Research lines

Modular schemes of solar thermal facilities for urban and industrial integration;

Advanced solar receivers and reactors (pressurised, volumetric and particle) and heat exchangers;

High-T thermal energy storage (thermochemical, sensible, PCM);

Solar fuels and chemicals production using metal oxides; and

Assessment of integration of solar energy in industrial processes, heat recovery & environmental impact (advanced thermodynamic cycles, water, glint, glare).

Facilities

Our research activities are organised around four major infrastructures: (i) The Computational Design Laboratory for High Temperature Processes (HTPU-CDL); (ii) the High Temperature Processes Laboratory (HTPU-LAB): (iii) the 42 kW High Flux Solar Simulator; and (iv) the IMDEA Energy’s solar field, consisting of 169 heliostats and a solar tower with two test platforms at 12 and 15 m height.
