オマーンの重質油層における熱増進回収法（EOR）の蒸気生成を対象に、天然ガス、グリーン水素、混合燃料の3シナリオを技術経済比較。天然ガスは低コストだが高排出、水素はほぼゼロ排出だが高コスト、混合燃料は排出を18-35%削減しつつ中程度のコストで移行策として有効。LCOSプレミアム5-15%でインフラ変更なしに実現可能。
English
This study compares techno-economic and environmental performance of steam generation for thermal EOR in Oman using natural gas, green hydrogen, and blended fuels. Natural gas offers lowest cost (6.6-8.5 USD/GJ) but high emissions; green hydrogen nearly eliminates emissions but at high cost; blended fuels reduce emissions by 18-35% with moderate cost and no infrastructure changes, serving as a transitional step.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本ではEORは主要ではないが、水素混焼やCCUS技術の経済性評価手法は、日本の火力発電や産業熱需要の脱炭素移行に応用可能。特にLCOSやNOx生成評価は、水素社会実現に向けた技術選択の参考になる。
In the global GX context
This paper provides a rigorous techno-economic framework for evaluating hydrogen blending in industrial heating, relevant to global efforts to decarbonize hard-to-abate sectors. The LCOS and NOx assessment methodology can inform transition strategies for natural gas-dependent industries worldwide, aligning with ISSB and transition finance disclosure needs.

📄 Abstract（原文）
Heavy oil reservoirs in Oman depends significantly on thermal Enhanced Oil Recovery (EOR) particularly Once-through Steam Generators (OTSGs), traditionally powered by natural gas as a fuel. However, this dependency produces substantial greenhouse gas emissions (GHG) that conflicts with Oman 2040 vision and the Net Zero 2050 commitments. This study presents a comparative techno-economic analysis and environmental assessment of three steam-generation pathways: 100% natural gas, 100% green hydrogen, and blended fuels scenarios (20-40% hydrogen in volume). A simplified thermodynamic model is developed to estimate thermal performance and fuel demand, supplemented by an indicative NOx formation assessment based on temperature dependent Zeldovich kinetics and mitigation needs. Natural gas (NG) achieves the lowest steam cost which is 6.6-8.5 USD/GJ but generates high emissions (500–650 kg CO2e/bbl). Green hydrogen offers nearly eliminated emission (<5 kg CO2e/barrel) but at a cost of 14.2-17.0 USD/GJ today. Blended fuels reduce emissions by 18-35%, while maintaining moderate cost of 8.5-11.3 USD/GJ without infrastructure modifications and LCOS premiums of 5-15% considering it a practical transitional step toward decarbonized thermal EOR in Oman.
