Large-scale green hydrogen production via chemical looping of unused biomass with optimized supply networks

Abstract

This study examines a hydrogen production system using unused biomass for large-scale industrial application. The process integrates chemical looping with a waste separation system for byproduct recovery. To improve efficiency, optimal transportation routes were identified to cut logistics costs and carbon emissions. A deterministic programming-based optimization model was applied for practicality. Economic and environmental assessments showed efficient resource use, lower hydrogen production costs, and reduced carbon emissions. This system reduces greenhouse gas emissions by over 68 % compared to conventional green hydrogen production, demonstrating its environmental advantage. The study introduces a novel approach by integrating chemical looping with biomass and optimizing transportation through electric vehicles. Additionally, multi-criteria decision-making was applied to develop operational strategies from government and corporate perspectives. This study offers a sustainable solution for hydrogen supply chains and outlines a pathway for carbon-neutral hydrogen production, providing insights for industry and policymakers aiming for a low-carbon economy. © 2025
