Project status

COVID-19: POLYPHEM is extended by 5 months

Since most facilities were closed during the COVID-19 context, the European Commission has approved an extension of 5 months for POLYPHEM. Therefore, the project will end in August 2022 instead of March 2022.

Deliverable 3.3: Report on Filler Material

POLYPHEM has submitted the deliverable D3.3 – Report on Filler Material – published within WP3 (R&D on Thermal Energy Storage System).

Periodic Reporting 1: Review of the first 18 months of POLYPHEM

The European Commission has published the first Periodic Report of POLYPHEM, which reviews the advancements achieved during the first 18 months of the project.

Preliminary system modelling (in WP7)

The first draft of optical simulation model of THEMIS heliostat field is established.

Measurement techniques (in WP6)

The technical specification of the circumsolar measurement camera is done.

Overall plant layout and integration of the subsystems (in WP4)

Face-to-face meeting between KAEFER and Fraunhofer ISE was held on May 9, 2018 to discuss about the specification and the operation conditions of the micro-gas turbine, the plant operating strategies and the control system.

Studies on fillers and modelling of thermal energy storage using thermocline (in WP3)

Jarytherm DBT is been chosen as HTF in the storage loop The partners shared their experience on HTF-solid compatibility testing through a common form and phone conference meeting. The partners also shared their experience on thermocline modelling through a common form.

Modification of the core-module of the gas-turbine (in WP2).

The integration scheme is under discussion in WP4. The results will be used to specify the modification needed for the combustor and additional manifolds of the gas-turbine.

Selection of materials for the solar receiver (in WP1)

CEA listed the candidate materials for the benchmark. 25 samples of 5 candidate materials were prepared by CEA and sent to CNRS for on-sun characterization. Samples have been defined for other optical characterization by CNRS and for coating by ARRAELA.
