米国インター・マウンテン・ウエスト（I-WEST）地域は天然ガス埋蔵量が豊富で、水素製造のリーダーとなり得る。しかし、水蒸気メタン改質（SMR）によるCO2排出や天然ガス・水素の漏洩が課題。炭素回収・貯留（CCS）を統合し、地域の水利用制約や漏洩削減を考慮した評価を実施。水素燃料電池車や100%水素発電への転換により、水消費と燃料コストを削減できる。
English
The Intermountain West (I-WEST) region in the USA has large natural gas reserves, positioning it as a potential leader in hydrogen production via steam methane reforming (SMR). However, CO2 emissions and fugitive losses of gas are challenges. This study assesses integrated carbon capture and sequestration (CCS) while considering regional water availability. It finds that siting SMR near wells reduces fugitive losses, and switching to hydrogen fuel cell vehicles and 100% hydrogen electricity reduces water consumption and fuel costs.

日本のGX文脈において
本論文は米国地域に限定されるが、日本でも水素製造とCCSの地域特性（エネルギー資源、水資源）を考慮する際の参考となる。日本の水素戦略は輸入水素に依存するため、生産段階の地域評価手法は輸入先選定に応用可能。
In the global GX context
This regional hydrogen assessment provides a model for integrating CCS with SMR while addressing water constraints and fugitive emissions. It offers insights for global hydrogen hubs, especially in regions with abundant natural gas and water scarcity, relevant for ISSB and TCFD disclosures on transition risks and opportunities in hydrogen infrastructure.

📄 Abstract（原文）
Given the large natural gas (NG) reserves of the Intermountain West (I-WEST) region in the USA, it can emerge as a leader in hydrogen (H2) production. Currently, H2 production via steam methane reforming (SMR) of NG releases carbon dioxide (CO2) and the natural gas infrastructure has fugitive NG and H2 losses during production, conversion and transportation. Integrated carbon capture and sequestration (CCS) is a promising approach for producing hydrogen and CO2 from the SMR process for industrial uses including power, chemicals and fuels. However, the NG losses and regional water availability can be limiting factors for H2 production. H2 production assessments are often made at the global scale and neglect regional factors such as abundant gas and limited water in the I-WEST. We demonstrate that a regional SMR process unit sitting near NG wells offers opportunities to significantly reduce fugitive NG losses. We show that regional H2 production by SMR has a lower emissions profile than widespread natural gas combustion in the I-WEST and reduces the H2 production cost as well. Replacing the I-WEST transportation sector with H2 fuel cell vehicles and using 100% H2-powered electricity can provide substantial reductions in water consumption and fuel costs. This is better than blending H2 with NG which is more expensive. The captured CO2 can be effectively used for enhanced oil recovery in I-WEST. Finally, the potential of utilizing produced, brackish and treated impaired water sources is assessed to meet the water needs for H2 production in the I-WEST.
