Reviewer 1 Report
To Authors
Some typos have been identified in this article. Also, the quality of Tables and Figures should be improved. The references that should be given in the text should be checked and the references that are not given should be rearranged. Likewise, the References section should be revised. Some typographical errors detected are given below. These need to be fixed.
Line 52 “greenhouse gases emissions (GHG)” should change with “greenhouse gases (GHG) emissions”
Line 190 “Phase Change Materials (PCM)” should change with“Phase Change Materials (PCMs)”
Line 274, 345 and 354 All unit in Table 1-2 should be checked to “SI Unit system”. Please, do not “dot” in the units. Such as “kg·m3”. İt should change as “kgm3”
Line 538 and 541 In Figure 17 and 18, the figures’s vertical axis and its unit should be checked. Of course, it should be change with “Temperatures (°C)”

Reviewer 2 Report
This study conducted a case study for decentralized heat storage solutions in the 2 agroindustry sector using phase change materials. The whole reasecrh are well investigated. There are some comments about this study and I hope they can help improve this study. (1) LTES has been widely applide in different industrial areas, and the Introduction of this study should review more references to dmeonstrate the superiority of LTES. You can refer following references: Applications and technological challenges for heat recovery, storage and utilisation with latent thermal energy storage. (2) Some figure should be improved to make clear the differences between different lines, such as Fig. 16, 17, 21, 22 (3) Simulation model of PCM should be validated.Author Response

Reviewer 3 Report
- Phase change material: Since the natural convection plays a significant role in the melting of PCM. How the authors include the convective heat transfer phenomenon.
- Line 288: Security issue? Please explain this
- Line 311: Error!! Plz provide a valid reference
- Figure 6: It is well known that the encapsulated spheres will provide the effective heat transfer rate. Even though they are not indirect contact with the heater (on the base). There are lot of references to prove this. Authors are requested to either prove this concept though simulation or experimentation. Or they can edit this figure and associated explanation.
- The PCM cyclic stability and heating rate during testing is very critical. Explain few lines on this. Authors may refer this work for further explanation. https://doi.org/10.1016/j.ijthermalsci.2020.106274
- CFD Simulation: This section needs a serious update. Plz include the grid independency and time step independence study. Without this, the present model is invalid.
- Also include the numerical equation/ mathematical model used to solve the phase change phenomenon.
- How the present CFD model is validated. Provide the details. This is so significant. The section on PCM type and selection is not required. Readers can easily got that information in all the books. The present numerical model must be validated with a reasonable degree of accuracy (%). Provide a graphical representation of the data for validation.
- Fig 11: Line for water bath is not shown
