For the past 5 years, Sirea has been collaborating with 9 other European companies and organisations in a Horizon 2020 project, funded by the European Union.
This project, called “MOSAIC”, aims at deploying and validating an innovative concept of solar thermodynamic power plant (CSP) with high efficiency and low implementation costs.
The consortium of which Sirea is a part has just completed the construction of the prototype (300 kW) at CENER (Centro Nacional de Energías Renovables), in Sanguesa, Spain.
Over the last few months, different systems have been tested using a dummy receiver connected to dummy pipes, simulating real conditions. Once the tests were completed, the receiver and pipes were replaced with real equipment.
The operation took place from 20 to 22 April 2021 and required the participation and cooperation of various partners and their subcontractors. The thermal installation is now complete and all its components are now operational.
The whole assembly was raised by a crane which lifted the real pipes, already connected to the receiver, while the receiver itself was lifted by the cables of the tracking system. The end of the pipes, opposite the receiver, was connected to the top of the main metal tower.

In the following days, the system will be filled with a high-temperature heat transfer fluid (HTF), and then the thermal loop system will be ready for the various tests that will evaluate its proper functioning.
The last step in this final phase will be the deployment of the solar array later this year.
