Life Cycle Assessment and Optimization Analysis of the Hydrogen-Integrated Industrial Park Energy System

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.
