中国山西省を対象に、5つの水素製造経路（石炭ガス化、コークス炉ガス、太陽光発電、風力発電）のライフサイクル炭素排出量を統一枠組みで評価。結果は風力発電由来水素が最も低炭素（1.57 kg CO2e/kg-H2）で、石炭系は操業段階、再生可能系は建設段階に排出が集中。経路別の削減戦略を提案。
English
This study assesses life-cycle carbon emissions of five hydrogen production routes in Shanxi, China, using a unified LCA framework. Results show wind power hydrogen has the lowest carbon intensity (1.57 kg CO2e/kg-H2), while coal-based routes emit mostly during operation and renewable routes during construction. Mitigation strategies differ by route.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本では、水素基本戦略のもとで水素サプライチェーン構築が進むが、本論文は実際のデータに基づくライフサイクル排出評価手法を示しており、日本の水素製造経路の比較評価や、CCS導入判断にも応用可能。特にグリーン・ブルー水素の定義と排出削減効果の定量化に参考になる。
In the global GX context
This paper provides a detailed LCA comparison of hydrogen production routes, relevant for global hydrogen certification schemes (e.g., CertifHy, ISSB standards). It highlights the trade-offs between coal-based hydrogen with CCS and renewable hydrogen, informing policy on hydrogen subsidies and carbon pricing.

📄 Abstract（原文）
Against the backdrop of China’s dual carbon goals (carbon peaking and carbon neutrality), hydrogen energy has emerged as a key strategic priority for Shanxi’s energy transformation. Understanding the carbon emission characteristics and mitigation potential of typical hydrogen production routes is essential for guiding the low-carbon development of the local hydrogen industry. This study applies a unified life cycle assessment (LCA) framework to evaluate five representative hydrogen production routes in Shanxi. A sensitivity analysis is conducted to assess the robustness of the results. The results show marked differences in carbon intensity across routes: large-scale integrated coal gasification hydrogen production (LICGHP, 10.02 kg CO2e/kg-H2) > commercial coal gasification hydrogen production (CCGHP, 9.35 kg CO2e/kg-H2) > photovoltaic hydrogen production (PHP, 6.17 kg CO2e/kg-H2) > coke oven gas hydrogen production (COGHP, 3.83 kg CO2e/kg-H2) > wind power hydrogen production (WPHP, 1.57 kg CO2e/kg-H2). For coal-based routes, emissions are concentrated in the operational phase, whereas for renewable routes, emissions are concentrated in the construction phase with near-zero emissions during operation. COGHP (61.78% mitigation rate) serves as an effective transitional pathway, and WPHP (84.33% mitigation rate) represents the best low-carbon option. Mitigation strategies vary by route: coal-based routes prioritize CCS and process optimization, while renewable energy routes focus on supply chain decarbonization and green construction. These findings offer scientific support for Shanxi’s hydrogen energy technology selection and low-carbon strategy formulation.
