本論文は、港湾環境内で統合された水素製造・供給チェーンをWell-to-Portの視点から評価する。バイオ水素、再生可能電力による電解水素、メタン改質水素の3経路を分析し、エネルギーPROソフトによるシナリオモデリングで各経路の資源使用、エネルギー集約度、環境性能を比較。機能単位は1MJの水素エネルギー（LHV）とし、PEFフレームワークとIPCCガイドラインに準拠した環境影響評価を実施した。
English
This paper assesses hydrogen production and supply chains integrated within seaport environments from a well-to-port perspective. Three pathways (biohydrogen, electrolytic hydrogen from renewables, and methane-based hydrogen) are analyzed using energyPRO scenario modeling. Key outputs include hydrogen volumes, energy inputs, efficiencies, and by-products. Environmental impacts are calculated following the PEF framework and IPCC guidelines, with a functional unit of 1 MJ hydrogen energy. Results highlight differences in resource use and environmental performance among pathways.

日本のGX文脈において
日本のGX政策では水素が重要戦略の一つであり、港湾は国際的なサプライチェーンの拠点として脱炭素化が急務である。本論文は、港湾における水素サプライチェーンの環境影響評価手法を提供し、日本での港湾水素ハブ計画やSSBJに基づく環境情報開示にも示唆を与える。
In the global GX context
This study provides a systematic well-to-port comparison of hydrogen production pathways relevant to global maritime decarbonization. It applies EU-aligned PEF methodology, offering a replicable framework for assessing hydrogen supply chain emissions. The findings are valuable for ports worldwide seeking to implement hydrogen strategies and for disclosure under TCFD/ISSB frameworks regarding transition risks and opportunities in shipping.

📄 Abstract（原文）
This research investigates hydrogen production and supply chains integrated within seaport environments using a well-to-port perspective to support the decarbonization of maritime and port-related activities. Three hydrogen production pathways are analysed: biohydrogen derived from biomass and waste streams, electrolytic hydrogen produced using renewable electricity, and methane-based hydrogen generated through reforming processes. Hydrogen transportation from production sites to the port area is included within the well-to-port system boundary and assessed through pipeline transport, road-based delivery, and on-site production options. The results are based on scenario modelling performed with the energyPRO software, which was used to quantify key input and output parameters for each production pathway. Model outputs include hydrogen production volumes, energy and feedstock inputs, electricity demand, process efficiencies, and associated by-products, providing a detailed comparison of system performance across scenarios. Environmental impacts are calculated using methods consistent with the Product Environmental Footprint (PEF) framework and emission factors aligned with Intergovernmental Panel on Climate Change (IPCC) guidelines. In accordance with EU PEF Category Rules principles, the functional unit is defined as 1 MJ of hydrogen energy (lower heating value) delivered to the seaport gate at the specified purity and pressure. The results highlight differences in resource use, energy intensity, and environmental performance among the assessed hydrogen production pathways.
