Periodic Reporting for period 1 - SOLARSCO2OL (SOLAR based sCO2 Operating Low-cost plants)
Berichtszeitraum: 2020-10-01 bis 2022-03-31
In particular, the novel SOLARSCO2OL layout, including shcematis, operating modes, limitations, scope, BoP were defined in T1.1 and T1.2. The pre-design layout has been identified, as well as the thermodynamic cycle with the preliminary P&ID including the interconnection among the different components. The KPIs, the bottom-up costs model and market related inputs for techno-economic optimization models were identified in T1.3 and started to be applied in T1.4 with the first results already analysed and discussed by KTH. The conceptual and preliminary design for both compressor and turbine have been completed, respectively by BH and FTM. For the compressor the detailed design is in progress, with a preliminary definition of the auxiliary systems already performed. For the turbine a detailed study on how the fluid can influence the rotordynamic stability has been performed by FTM, in parallel with the assessment of the most suitable materials to realize the turbine, considering the project operating conditions and possible future up-scales. The preliminary design and CFD modelling was also almost completed for the Heat Exchangers and Electric Heater, respectively by LOINTEK and SEICO.
The main control variables have been identified and the system modelled in Matlab/Symulink environment. The variables have been tested through off-design and dynamic analysis, with different load conditions to determine the performance map of the whole cycle under different control logics. The preliminary control strategy has been studied, developed on the basis of the off-design analysis. A clear Visual identity has also been developed for the project, with the preparation of Dissemination material such as Logo, Leaflet, Poster and Roll-up, the launch of the project website and social media channels and the preparation of the preliminary plan for Exploitation, Dissemination and Communication. A project video has also been published on SOLARSCO2OL youtube channel.
The environmental and social acceptability of SOLARSCO2OL plant will be studied via LCC/LCA/s-LCA methods, ensuring the social viability of sCO2 and CSP plants and promoting for the first time sCO2 as the best operating fluid in turbomachinery for the future EU RES Based scenario, thanks to sCO2 higher efficiency, lower capex, lower operating temperature, which make sCO2 perfect to be coupled with a large variety of systems. The replication of SOLARSCO2OL layout will be then studied both in EU and extra EU countries, ensuring the developing of suitable business models to promote the replication of the concept in current and future CSP plants.
Finally a strong Dissemination and communication strategy will ensure the soundness of SOLARSCO2OL results, proposing the project with relevant stakeholders and presenting it in multiple events.
