The project started in April 2018. The Kick-off meeting was held in Brussels on April 26, 2018.
The first draft of optical simulation model of THEMIS heliostat field is established.
The technical specification of the circumsolar measurement camera is done.
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.
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.
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.
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.
The approach proposed in the project is a new design of small-scale CSP plants. The project prepares the next generation of small-scale CSP plants with high performance combined cycle and flexible generation of renewable electricity with firm capacity. The proposed cycle features a reduced water requirement compared to steam Rankine cycle. The optical efficiency of small solar tower system is higher than that of any other solar field. Combined with the potential high conversion efficiency of the thermodynamic cycle, the resulting efficiency allows for additional reduction of the size of solar field. Micro gas-turbines and small ORCs have proven their reliability in the long-term. The technology developed in the project offers an extended range of designs by varying the size of the components, each design being optimized for a specific need (power generation, cogeneration, heating/cooling, water desalination).
