カナダの天然（地質）水素について、地質的賦存性・技術経済性・環境影響・政策整備度を構造的文献レビューとCAPEX/OPEX/LCOHによる試算で評価したレビュー。カナダ楯状地や西部堆積盆地等に有望な地質条件がある一方、商業化は地下賦存の確認や流量・純度・深度・インフラ近接性に左右され不確実。試算では供給コスト約2.10USD/kg、流量・純度・深度・輸送が主要コスト要因。州ごとの政策枠組みが不均一で、規制整備が今後の役割を左右すると結論。
English
A structured review assessing natural (geologic) hydrogen's role in Canada's net-zero transition across geology, techno-economics, environment, and policy. Canada shows favorable geology (Canadian Shield, Cordillera, Western Sedimentary and Williston Basins), but commercial viability hinges on confirmed accumulations, flow rates, purity, depth, and infrastructure proximity. Screening suggests ~USD 2.10/kg delivered cost, with flow rate, purity, depth, and transport as dominant drivers. Provincial policy remains uneven, so deployment depends on clearer regulation.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本は水素を脱炭素の柱としつつ輸入依存が高く、天然水素は調達多様化の観点で注目に値する。カナダの州別規制の不均一さは、日本の水素政策・サプライチェーン設計を考える上での比較材料になる。
In the global GX context
Natural hydrogen sits at the frontier of global hydrogen strategy, relevant to ISSB/transition-finance debates on credible low-carbon pathways. Canada's province-level regulatory fragmentation offers a case study for how policy readiness shapes emerging energy sources.

📄 Abstract（原文）
Natural hydrogen, or geologic hydrogen, is increasingly being considered a potential low-carbon energy source for Canada’s net-zero transition. This review evaluates the extent to which natural hydrogen can contribute to Canada’s low-carbon energy transition by examining its geological prospectivity, techno-economic viability, environmental considerations, and policy readiness. This review is based on a structured literature review of peer-reviewed journal articles and government and industry reports, supported by a techno-economic screening of production, purification, and transportation costs using CAPEX, OPEX, and LCOH as primary indicators. The results show that Canada has favourable geological conditions for natural hydrogen generation and accumulation, particularly within the Canadian Shield, Cordillera, Western Sedimentary Basin, and Williston Basin. However, commercial viability remains uncertain, hinging on confirmed subsurface accumulations, sufficient flow rates, high wellhead purity, appropriate well depth, and proximity to infrastructure and end-use markets. Preliminary screening suggested a delivered hydrogen cost of approximately USD 2.10/kg, with sensitivity analysis identifying well flow rate, purity, depth, and transportation needs as dominant cost drivers. Although natural hydrogen presents lower emissions than conventional hydrogen, issues such as leakage, groundwater disturbance, land use, and monitoring requirements must be addressed in future studies. Policy frameworks remain uneven across provinces, indicating that the role of natural hydrogen in Canada's low-carbon energy transition will depend not only on geological prospectivity but also on commercial viability and clearer regulatory guidance.
