Up to now, research efforts focused on the global efficiency of the TCES associated to different power cycles under fixed modes of operation: day or night. However, TCES will never operate under a stationary situation but will experience different operation points to adapt to solar availability and energy demand from the power cycle. The aim is to analyse the influence of those variables which define the operation points, under energy storage and release modes, in the design of the heat exchangers network, storage tanks and reactors involved in the TCES system. The equipment in the conceptual plant have been modelled accounting variable storage/discharge fractions in the mass balances. The results show a suitable capture efficiency, quantifies the stored power and define the size and performance of the heat exchangers required to operate the system. The behaviour of each heat exchanger and their relevance in heat integration with a power plant is derived. The novelty relies in the analysis of potential situations arising from different combinations of charge/discharge fractions of storage tanks. info:eu-repo/grantAgreement/ES/DGA/T46-17R info:eu-repo/grantAgreement/EC/H2020/727348/EU/SOlar Calcium-looping integRAtion for Thermo-Chemical Energy Storage/SOCRATCES This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 727348-SOCRATCES info:eu-repo/grantAgreement/ES/MCIU/FPU17-03902 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 8.857 2021 THERMODYNAMICS 3 / 63 = 0.048 2021 Q1 T1 ENERGY & FUELS 24 / 119 = 0.202 2021 Q1 T1 2.041 2021 Energy (miscellaneous) 2021 Q1 Energy Engineering and Power Technology 2021 Q1 Building and Construction 2021 Q1 Civil and Structural Engineering 2021 Q1 Renewable Energy, Sustainability and the Environment 2021 Q1 Management, Monitoring, Policy and Law 2021 Q1 Mechanical Engineering 2021 Q1 Modeling and Simulation 2021 Q1 Fuel Technology 2021 Q1 13.4 2021 info:eu-repo/semantics/article info:eu-repo/semantics/acceptedVersion Lisbona, Pilar Universidad de Zaragoza (orcid)0000-0002-2306-6729 Bailera, Manuel Universidad de Zaragoza (orcid)0000-0002-9174-9820 Romeo, Luis Universidad de Zaragoza (orcid)0000-0001-7379-6159 5004 590 Universidad de Zaragoza Dpto.
