A Low-Carbon Optimal Operation Method for an Industrial Park Multi-Energy Coupling System Utilizing By-Product Hydrogen
Round 1
Reviewer 1 Report
Comments and Suggestions for AuthorsThe article presents an interesting approach to the energy transition scenario in the industrial segment.
I only suggest small adjustments such as:
Improvement and facilitation of results graphs and the creation of a comparison between scenarios.
Include an analysis based on the results and scenarios regarding replicability in other segments or production sectors.
Review to correct minor formatting errors to adapt to the magazine.
Finally, we include some suggestions for optimizing the structure in search of improving efficiency and direct energy use.

Reviewer 2 Report
Comments and Suggestions for AuthorsThis manuscript proposed a Multi-Energy System with By-product Hydrogen, which can effectively increase the industrial park revenue and reduce carbon emissions at the same time by effectively utilizing the by-product hydrogen from the chlor-alkali plant. The reviewer would suggest publication after the following issues solved.
Line 53-55, should briefly discuss why only 60% of by-product hydrogen is recovered?
Line 65-67, what would be the cost to purify the hydrogen for fuel cell?
Line 102, avoid using ‘in conclusion’ in the introduction section.
Equation 1: should give more information about k0 and U0 or give references.
Table 2. How are these parameters determined.
Section 5.2, could the authors provide more details about how are the 1000 scenarios generated and how are they reduced to 10?
Figure 6, is the predicted load curve the average of the 10 curves?
Line 539-550, to implement case 4, what would be the increased capital cost and what would be the increased maintaining cost for this system?

Title: A Low-Carbon Optimal Operation Method for an Industrial Park Multi-Energy Coupling System Utilizing By-Product Hydrogen
This paper proposes a scenario generation and reduction method that considers the spatiotemporal correlation of source-load variables. Studies the correlation in production between sources and loads within the chlor-alkali chemical park.
In the introduction, the authors mention that “only about 60% of the by-product hydrogen is recovered and utilized, with the majority being inefficiently used or wasted.” However, they do not identify the causes for this waste. It would be important to make this identification.
The authors should provide a more detailed explanation of Figure 1. It is crucial for understanding the presented study.
The authors do not mention the quality of the produced hydrogen. Can it be used directly?
In section 2.1.1, Ionic Exchange Membrane Electrolyzer Model, the authors mention the equation that allows determining the electrical power of the electrolyzer. Who will define this power, the industrial process, or the hydrogen production?
The remaining sections of the paper are well-structured with relevant technical information, allowing for the identification of the potentialities of the developed methodology.
The authors should review the text and correct some spelling and grammatical lapses.
