The new multicoated polymeric mirror was designed, upscaled, manufactured and installed in a pilot plant. NEMATIA worked on mirror design, and tools for its fabrication. GEOCAD work on full injection process of substrate and protective coating. KOLZER developed tools for reflective process deposition for high reflective KPI looking to reduce high cots reflective metal. VOTTELER and LEITAT worked together in developing an optimal combination of antisoiling and protective coating. A portfolio of different multicoated mirror was achieved, that were exposed in accelerated and natural aging conditions carried out by LEITAT and TEKNIKER. All fully coated mirrors kept their performance after these tests, including in exposition in extreme conditions. Upscaled mirrors were installed in Linear Fresnel pilot loop under real operation conditions in MAGTEL’s site. Reduction in CAPEX and higher environmental profile were calculated. The results are patented, and different path of exploitation are opened. In parallel, LEITAT developed a new antisoiling for mild environmental conditions for glassy PV modules which was under evaluation in a PV loop on MAGTEL’s site. The results were communicated in workshop with stakeholders.
TEKNIKER developed the optimal multilayer configurations for absorber coatings. Stacks of layers comprising IR reflecting mirror, absorber and antireflective layer were defined, modelled, characterized and tested. Values of absorbance accomplished the expected target and an impressive reduction in emissivity was achieved. Several types of absorber coatings were developed, for evacuated tubes operating at high and medium temperature regime; and totally innovative absorber coating for air operation and high temperature. The developed tubes were tested in two pilot plants, Parabolic Through collector and LF loop in ENEA and MAGTEL respectively. The results accomplished the expected KPIs, and patent is in progress.
The new TES materials and systems were developed and modelled. FERTIBERIA worked on a new formulation of eutectic mixtures, achieving targeted KPIs. CEA worked on low-cost processes for encapsulated phase change materials avoiding corrosion. Those materials were tested in ENEA and CEA achieving expected performance. Using the properties of the new materials, CEA and ENEA developed and validated a modelling procedure bringing a portfolio of TES systems. The results were disseminated in scientific publications and open online public webinar; and communicate in workshop with stakeholders. Patents about those results are already in progress and new ways of exploitation are under execution.
A lightweight composite-based component, selected by LEITAT and MAGTEL, were defined, commissioned, and installed in a PV loop in MAGTEL’s site for validating the behavior of this component in a solar field. The results indicate a very assured performance for future solar fields. An open day for student allows them to visit the pilot plant and explain the future in CSP technology.
Finally, for estimated annual energy production (AEP), a modelling of PTC has been done showing better performance, and an open model for LCOE calculus estimates a reduction in according to IN POWER economic KPIs. CAPEX reduction has been achieved in all the components, and higher AEP is predicted with them.
