This approach involves reflecting sunlight back into space while allowing Earth's infrared radiation to escape, thereby controlling climate change. The effectiveness of space solar shielding is evaluated using a complex algorithm that considers various parameters of the shielding satellite, such as its size, orbit, and deployment mechanism. The thickness of the shield should be similar to the solar wavelength, around 400-600 nm, to deflect sunlight with an expected mass density lower than 1.5 g/m<sup>2</sup>. The primary objective is to reduce the greenhouse effect by mitigating the increase in atmospheric carbon dioxide (CO<sub>2</sub>) levels. In 2022, CO<sub>2</sub> levels in the United States surpassed the pre-industrial level of 278 ppm, increasing by approximately 7.11 ppm due to the consumption of coal, natural gas, and petroleum for electricity generation. This point reflects the relatively recovered climate environment at the end of the pandemic. Therefore, long-wavelength solar radiation energy going out from the Earth is absorbed and increases the temperature of the Earth's atmosphere, so we want to reduce the solar energy coming into the Earth. The performance of space solar shielding is analyzed using a system dynamics (SD) model, which incorporates feedback loops and non-linear relationships between various variables. The results indicate that while the effectiveness of CO<sub>2</sub> reduction may diminish over time, the overall climate mitigation benefits could be significant. However, the large scale of space solar shielding raises concerns about potential side effects. Further research is necessary to assess the environmental and socio-economic implications of this geoengineering approach.</p>","PeriodicalId":11673,"journal":{"name":"Energy Science & Engineering","volume":"13 4","pages":"1653-1661"},"PeriodicalIF":3.5,"publicationDate":"2025-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ese3.2083","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143852990","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This shift is accompanied by an increase in mining height and a rise in the degree of automation, leading to uneven and potentially violent settlement of overlying rock formations, as well as the formation of single or multi-layer separation spaces above the coal seam. If the water-conducting fracture zone intersects with the water-bearing separation layer, it can result in catastrophic mine accidents such as water gushes and sand collapses on the working face. Based on the research background of a specific working face in the No.7 coal seam at Qianjiaying Mine, this study employs empirical formulas, BP neural networks, similarity simulations, and UDEC numerical simulations to investigate the evolution of overburden fractures and the development of separation layers under high-intensity mining conditions. The study also analyzes the water inrush modes and mechanisms of separation layers in high-intensity mining, leading to the following conclusions: (1) By collecting data from 42 different coal mining faces in China, empirical formulas and BP neural network prediction models for the development height of the water-conducting fracture zone in overlying rock were established. The relative and absolute errors of the prediction results from both models were compared. For 90% of the predicted data, the error rate of the BP neural network model was less than 0.5%, with an average error of approximately 3%. (2) Through two similar simulation tests, where only the mining height of the coal seam (3 and 6 m) was varied while controlling other variables, it was concluded that higher mining heights lead to more severe damage and obvious fracture development in overlying rock. The presence of a main key layer and thick sandstone increases the expansion time and duration of the separation space. Overburden failure in high-intensity mining exhibits a “Π” shape, with the failure height primarily influenced by the high-intensity mining mode, overburden structural combination, and the load of the “beam-arch structure,” as well as the overburden dilatation coefficient. (3) Numerical simulation results indicate that under different mining height conditions, larger mining heights result in more pronounced settlement of the main key layer, with step subsidence and sliding phenomena observed on both sides of the key layer. (4) Based on the aforementioned research methods, this paper explores the formation mechanisms of separation layers in both single-seam and multi-seam mining, focusing on the analysis of repeated disturbances in multi-seam mining, dynamic water inrush, and structural water inrush modes. It comprehensively elucidates the mechanisms of separation layer water inrush in high-intensity mining.</p>","PeriodicalId":11673,"journal":{"name":"Energy Science & Engineering","volume":"13 4","pages":"1896-1921"},"PeriodicalIF":3.5,"publicationDate":"2025-02-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ese3.70016","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143852930","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, IES operations are influenced by various factors, such as equipment performance, energy flow dynamics, and load management, which are often overlooked in traditional optimization approaches. This study develops a novel hydrogen-compressed natural gas (HCNG)-IES model and operational strategy to address these challenges. An equivalence framework is established between electricity and hybrid gas, enabling the creation of an equivalent circuit model integrating electricity, heat, HCNG, H<sub>2</sub>, and NG. This model captures the intricate interactions and dependencies amongst energy equipment, multi-energy flow, and consumption loads. An optimized operational strategy is proposed, leveraging variable H<sub>2</sub> content in the gas mixture and adaptable thermal loads, while accounting for the energy inertia of H<sub>2</sub> storage and building systems to maintain supply–demand balance. Case studies reveal that incorporating HCNG technology increases renewable resources utilization, reducing operational costs, carbon emissions, and primary energy consumption by 23%, 24%, and 23%, respectively. Moreover, compared to conventional NG-IES optimization focused solely on equipment output, the proposed HCNG-IES approach achieves reductions of 28.12% in costs, 24.36% in carbon emissions, and 39.13% in primary energy consumption.</p>","PeriodicalId":11673,"journal":{"name":"Energy Science & Engineering","volume":"13 4","pages":"1858-1870"},"PeriodicalIF":3.5,"publicationDate":"2025-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ese3.70005","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143852928","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
