カナダ東部（大西洋4州とケベック）を対象に、再生可能水素の大規模生産と地中貯蔵（塩層空洞・枯渇炭化水素貯留層）のポテンシャルを定性的に評価した研究。年間を通じた高品質な風況、浅海域、送電網、深水港、塩層構造が水素産業を支え得ると結論。電解・圧縮・転換時の廃熱を地域熱供給や温室等へ活用することでシステム効率と脱炭素効果が高まると指摘し、州間・連邦の計画調整の重要性を強調する。
English
This study qualitatively assesses large-scale renewable hydrogen production and geostorage potential in Eastern Canada (four Atlantic Provinces and Québec). It finds strong year-round wind, shallow offshore seabed, grid connectivity, deep-water ports, and extensive salt structures suitable for massive hydrogen geostorage. Integrated production-storage systems could enhance long-duration storage and grid stability, with waste heat reused for district heating and greenhouses, while coordinated interprovincial and federal planning is emphasized.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本は水素・アンモニアの大規模導入と海外調達を脱炭素戦略の柱とするが、国内に塩層地中貯蔵の適地が乏しく、海外水素サプライチェーンの受け入れ側インフラ整備が課題。本稿は水素地中貯蔵と系統安定化の統合設計という観点で、日本の水素輸入・貯蔵戦略やGX推進の参考になる。
In the global GX context
As global hydrogen trade scales, geostorage in salt caverns and depleted reservoirs is emerging as critical infrastructure for long-duration energy storage and grid balancing. This paper adds a regional Canadian perspective to the international hydrogen supply-chain and storage literature relevant to transition finance and national decarbonization planning.

📄 Abstract（原文）
Energy storage systems, in a variety of forms and scales, contribute substantially to energy conservation while ensuring a reliable, efficient, and sustainable energy supply in modern hybrid energy systems. Storing the massive volumes of hydrogen required to meet future global supply chain demands can be achieved through geostorage in caverns in subsurface salt structures, created by controlled dissolution of the salt, and depleted hydrocarbon reservoirs. This study qualitatively but systematically assesses the potential use of geostorage solutions for large-scale energy storage in the Canadian Eastern region to support the renewables-to-hydrogen industry. The qualitative assessments indicate that the four Atlantic Provinces and Québec possess great potential for national-/international-scale hydrogen production with high-quality year-round wind resources, extensive shallow offshore seabed areas suitable for wind turbine deployment, extensive and expanding electrical grid connectivity, deep-water ports, and extensive salt deposits with structures suitable for massive geostorage. The assessment also demonstrates that integrated hydrogen production and geostorage systems can support large-scale renewable energy utilization while enhancing long-duration energy storage and grid stability. Furthermore, a portion of the waste heat generated during electrolysis, hydrogen compression, and chemical conversion processes can be utilized for district heating, greenhouse operations, compressed-air energy heat provision, and industrial applications, improving overall system efficiency and reducing fossil fuel usage and carbon-based emissions. The qualitative assessments also highlight the importance of coordinated interprovincial and federal planning to support long-term decarbonization efforts and develop sustainable, reliable geostorage-based hybrid energy systems.
