Abstract

Hydrogen energy is a rapidly growing source of clean energy, and it has now become an important part of the sustainable energy system. This study focuses on the full life cycle environmental benefits and optimization path of hydrogen energy in industrial parks, and innovatively constructs a full chain integration model of hydrogen energy. Based on the life cycle assessment (LCA) methodology, the energy demand and greenhouse gas emissions of the system are quantified by analyzing manufacturer data and the Ecoinvent database. LCA allowed a systematic assessment of the environmental footprint and economic viability of hydrogen production, storage, transportation, and utilization. The results show that the EPBT and GPBT of the hydrogen-integrated industrial park energy system are 11.9 and 7.1 years, respectively. Based on the results of the life cycle assessment, optimization strategies to further reduce carbon emissions are proposed. This study breaks through the limitations of the traditional single-link analysis method and establishes a decision-support framework that combines carbon reduction strategies with infrastructure optimization. The results of the study provide feasible insights for advancing the energy transition of cities and towns.

氢集成工业园区能源系统生命周期评价与优化分析

氢能是一种快速发展的清洁能源，现已成为可持续能源体系的重要组成部分。本研究聚焦工业园区氢能全生命周期环境效益与优化路径，创新构建氢能全链条整合模型。基于生命周期评估（LCA）方法，通过分析制造商数据和Ecoinvent数据库，对系统的能源需求和温室气体排放进行量化。LCA允许对氢气生产、储存、运输和利用的环境足迹和经济可行性进行系统评估。结果表明：氢集成产业园能源系统的EPBT和GPBT分别为11.9和7.1年；基于生命周期评价结果，提出了进一步降低碳排放的优化策略。本研究突破了传统单环节分析方法的局限性，建立了碳减排战略与基础设施优化相结合的决策支持框架。研究结果为推进城镇能源转型提供了可行的见解。

期刊介绍： Energy & Fuels publishes reports of research in the technical area defined by the intersection of the disciplines of chemistry and chemical engineering and the application domain of non-nuclear energy and fuels. This includes research directed at the formation of, exploration for, and production of fossil fuels and biomass; the properties and structure or molecular composition of both raw fuels and refined products; the chemistry involved in the processing and utilization of fuels; fuel cells and their applications; and the analytical and instrumental techniques used in investigations of the foregoing areas.
