本論文は、中国河北省の鉄鋼・セメント・化学クラスター向け低炭素水素供給経路のライフサイクルアセスメントを実施。電解、ガス改質＋CCS、石炭ガス化＋CCS、バイオマスガス化＋CCSを比較し、最良経路でもほぼゼロ排出には至らず、気候性能・大気汚染・インフラ間にトレードオフがあることを示した。
English
This study conducts a life cycle assessment of low-carbon hydrogen pathways for steel, cement, and chemical clusters in Hebei Province, China. It compares electrolysis, natural gas reforming with CCS, coal gasification with CCS, and biomass gasification with CCS. Results show substantial GHG variation, with best pathways approaching near-zero but not reaching it, highlighting trade-offs between climate, air quality, and infrastructure.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本でも水素を産業脱炭素の鍵と位置づけており、河北の事例は日本の工業地域（例：京浜・阪神）における水素インフラ計画やCCS導入検討に示唆を与える。ただし中国の電力ミックスや政策環境の違いに注意。
In the global GX context
This paper provides empirical LCA evidence for hydrogen pathways in a major industrial region, informing global discussion on hydrogen's role in industrial decarbonization. Its trade-off analysis (climate vs. air pollution vs. infrastructure) is directly relevant to ISSB/TCFD-aligned transition planning and national hydrogen strategies.
👥 読者別の含意
🔬研究者:LCA practitioners can use the comparative methodology and regionalized inventory data for further hydrogen pathway studies.
🏢実務担当者:Industrial cluster planners can assess the trade-offs among hydrogen options for decarbonizing their own operations.
🏛政策担当者:Policymakers in hydrogen strategy should note that even best pathways may not achieve near-zero emissions, requiring complementary measures.
📄 Abstract（原文）
Hydrogen is increasingly promoted as a strategic vector for decarbonizing industrial energy demand, yet environmental outcomes depend strongly on production pathways and regional context. This article applies a life cycle assessment framework to low-carbon hydrogen options supplying steel, cement and chemical clusters in Hebei Province in northern China. The analysis compares hydrogen from grid-connected electrolysis with a progressively decarbonized power mix, natural gas reforming with carbon dioxide capture, coal gasification with carbon dioxide capture and biomass gasification with carbon capture and storage. System boundaries cover upstream resource extraction, plant construction, operation, transport and end-use combustion or process use. Results indicate substantial variation in life cycle greenhouse gas emissions, with the best performing pathways approaching, but not necessarily reaching, near-zero emission levels. Trade-offs emerge between climate performance, air pollutant co-benefits and infrastructure requirements. The findings inform regional industrial decarbonization strategies and highlight priority areas for technology improvement and policy support.
