“…Those prototypes have been useful for measuring some thermal and mechanical parameters of concrete during the operation at high temperatures up to 400 • C. Numerical simulations of CTES have also reported the feasibility and cost-effectiveness of this type of thermal energy storage material (Vigneshwaran et al, 2019). However, most simulations are made assuming thermal properties with constant values, that is, considering them as temperature-independent properties (Vigneshwaran et al, 2019;Xu et al, 2017;Bai and Xu, 2011;Chen et al, 2019;Jian et al, 2015;Buscemi et al, 2018;Bataineh and Gharaibeh, 2018;Giannuzzi et al, 2017;Salomoni et al, 2014). Additionally, due to the high difficulty of evaluating these properties at high temperatures, in many studies, the thermal conductivity obtained at room temperature is used for the simulations (Doretti et al, 2019).…”

“…The velocity of the fluid flows is considered to be 0.004 m/s, and a temperature of 380°C and the initial temperature of concrete system is 340°C. This range is chosen because it is the approximate range in which the collectors of thermal CSP plant are designed to operate, the inner and outer radii were chosen based on studies and the experience mentioned in the literature [24][25][26]. Table 1 reports the thermo-physical characteristics of the materials that have been analysed in this case study and the technical characteristics that are inserted as parameters in the optimisation problem.…”

This study presents a comprehensive decision support model formulated as a finite-horizon-constrained optimisation problem to optimally design the geometry variables that maximise the net present value (NPV) associated to the thermal energy storage (TES) investment over a given time horizon. This study faces one of the main problems in a TES, which is to react to the unpredictable production/demand processes, by determining a high-level optimal size of the TES maximising the NPV that captures the storage benefits as well as detailed fixed and variable costs over a chosen time horizon. The storage benefits are defined, so that they model the costs of the expected discharged thermal energy over a year. Moreover, the authors account for various costs model regarding the total costs of the heat transfer tube material, the storage material, and the insulation material. The proposed decision model can be considered as practical framework that can support engineers and decision makers in the process of design and planning of future. They investigate performance and efficiency of the proposed decision support system framework through representative case studies. Numerical studies demonstrate the usefulness and efficacy of the proposed decision model.
