本研究は、バイオマスメタノール（林業残渣由来）とリサイクルカーボンメタノール（セメント由来CO₂利用）の排出量を比較する統一的な枠組みを提案する。水素調達と電力炭素強度を変数とし、炭素回避コストを用いて実装可能性を評価する。排出性能は上流のエネルギー条件や閾値行動、規模制約に大きく依存することを示す。
English
This thesis develops a unified comparative emissions framework for methanol pathways, treating hydrogen sourcing and electricity carbon intensity as variables. It applies the framework to biogenic methanol from forestry residues and recycled-carbon methanol from cement-derived CO₂, using carbon avoidance cost to assess deployment feasibility. Results show that emissions performance is governed by upstream energy conditions, threshold behavior, and intrinsic scale constraints.

📄 Abstract（原文）
Methanol has been proposed as a low-carbon fuel and chemical feedstock for the energy transition, yet reported emissions outcomes vary widely and often rely on assumptions that do not reflect transitional energy system constraints, limiting deployment relevance. This thesis addresses that gap by developing a unified comparative emissions framework that treats hydrogen sourcing and electricity carbon intensity as variables. The framework is applied to biogenic methanol from forestry residues and recycled-carbon methanol from cement-derived CO₂, using carbon avoidance cost to assess deployment feasibility and showing how emissions performance is governed by upstream energy conditions, threshold behavior, and intrinsic scale constraints.
