Discover the steps of the construction of the MOSAIC prototype !

Our consortium, made of European partners from 6 countries, has regularly published news about the construction site in Spain. To make the process clearer, we have created this explanatory video that sums up the important milestones along the progress of the construction, as well as the roles of each partner and the steps ahead. It will be updated with the remaining steps, once the project is completed in November.

Enjoy watching !

News from the construction site: receiver placed in the oven!

The MOSAIC project has reached a new important milestone: the first access of the receiver to the oven for heating-up procedure testing. On 15th June, the prototype site was ready for this manoeuvre, which allows the receiver to be placed inside the oven for heating process or to prevent high temperature losses from the receiver (during night, for example).

The complete manoeuvre in this specific installation consists of the following steps:

  1. The receiver is placed by means of the tracking system control in a vertical position, just in front of the oven. The upper crossbars of the receiver are laid on a specific retractable support.
  2. This support moves to the oven, placing the receiver in its right position.
  3. The doors of the oven close. The isolation parts of the receiver at its ends fit with the oven doors, so the receiver is kept in an isolated space, where the heating-up process can take place.

When the receiver is needed to move from the oven to the workspace, the inverse manoeuvre is carried out.

See the whole process in this video (accelerated 20 times):

From now onwards, the prototype can be tested with HTF preheating at intermediate temperatures, a previous step before the solar field is built and the higher temperatures are reached.

A significant milestone reached in MOSAIC project: real receiver installed !

During the last months, different systems had been tested by means of a dummy receiver connected to dummy hoses, simulating work conditions. Once the tests were completed, both the receiver and the hoses were replaced by the real ones. The operation was carried out from 20th to 22nd April and needed the participation and the cooperation of different partners and their subcontractors. The thermal installation is now complete with its real components.

The elevation of the ensemble was performed by means of a crane which lifted the real hoses, already connected to the receiver, while the receiver itself was lifted by the tracking system cables, in a coordinated operation. The hoses’ end, opposite to the receiver, was connected to the skid installation, on top of the main metallic tower.

In the following days, the system will be filled with HTF, and then the thermal loop system will be ready for the different tests that will assess its fine working. In a few weeks the solar field will be installed, before the start of the final period of set-up tests. Stay tuned for more news !

MOSAIC is entering its final phase !

The prototype at Cener facilities in Sangüesa is on its way towards its final state, as depicted in this video created by Increscendo:

Here is a brief overview of the last works carried out on the construction site:  

  • The mounting towers for the mobile elements and the oven have been erected.
  • The mechanical, optical and electrical elements of the tracking system have been installed and are being tested.
  • The innovative dummy hoses have been connected to the receiver.
  • The meteorological station has been connected to the tracking system, and the DCS of the whole prototype has been updated to achieve a full control of the plant.

The next key step will be the installation of the field of the solar mirrors, along with the evaluation of a watering system for the mirrors.

For more information about the tracking system, have a look at the latest news by Tekniker.

MOSAIC presented at INPOWER worskhop

Outcomes of the MOSAIC project were presented during the workshop dedicated to the topic “Materials & Processes for Thermal Solar System”. Half-day online workshop was organized within the framework of  H2020 funded project IN POWER on 27 October 2020.

MOSAIC project results were presented through presentation by Cristobal Villasante (TEKNIKER) on the topic TEKNIKER’s approach to the technological challenges of CSP. 

Livestream from the presentation is available here

MOSAIC prototype construction report: 5th tower installed

After a few months of break due to the COVID-19 pandemia, the MOSAIC prototype construction has restarted during June 2020 in Sanguesa (CENER). As you can see from the picture, all five towers have been successfully erected. At the moment, work onsite is focused on the tracking system and related support cables. In the coming months, we will update the onsite construction development. Stay tuned!

MOSAIC results in the Results Pack on Solar Heat for Power and Industry

An article related to the MOSAIC project results has been included in the Results Pack on Solar Heat for Power and Industry on Cordis: https://cordis.europa.eu/article/id/421789-a-mosaic-of-shiny-hollow-spheres-works-its-magic-on-sunlight?WT.mc_id=exp A Results Pack is a thematic collection of project results tailored to the needs of specialized audiences who can further exploit them. We are glad that MOSAIC concept has been selected for his potentially as exploitation results.

High-temperature solar receiver and thermal loop designed ready to be installed

After the COVID-19 break, MOSAIC consortium has restarted the prototype implementation with the high-temperature solar receiver and thermal loop construction, as announced by CSP Aalborg in the Helioscop news. The project has just now reached an important milestone as the receiver and skid have reached their final destination in Sangüesa. Here the items will be lifted to their final position at the top of the central MOSAIC steel tower.

MOSAIC projects results published in ENERGIES and Helioscsp

Two important dissemination activities have been finalized in the last months: the peer-reviewed paper “Low-Cost Solar Electricity Using Stationary Solar Fields; Technology Potential and Practical Implementation Challenges to Be Overcome. Outcomes from H2020 MOSAIC Project” has been published in February 2020 in ENERGIES to present the potentialities of the Low-Cost Solar Electricity Using Stationary Solar Fields. And an important article “Outcomes from H2020 MOSAIC Project” has been published in the Helioscop specialized online magazine. More news related to MOSAIC results will come soon so stay tuned!
