再生可能水素と持続可能な炭素源を用いる真にグリーンなメタノール経路を、155件の文献レビューで整理した。化石由来プラントの改修は移行的扱いとし、電解・光触媒など未成熟経路も含め、技術成熟度・エネルギー需要・ライフサイクル排出・平準化コスト・原料供給・インフラ・運用柔軟性で比較した。TEA/LCA比較可能性のプロトコル、統合評価の条件付きルール、地域別経路選択マトリクス、動的検証ギャップ分析の4点を提示し、普遍的優位経路は存在しないと結論づける。
English
A review of 155 publications maps genuinely green methanol routes based on renewable hydrogen and sustainable carbon, plus transitional fossil retrofits and less mature electrochemical or photocatalytic options. It compares technical maturity, energy demand, life-cycle emissions, levelized cost, feedstock supply, infrastructure, and operating flexibility, and examines when power-hydrogen-carbon integration is justified. Outputs include a TEA/LCA comparability protocol, conditional integration rules, a regional pathway-selection matrix, and a dynamic-validation gap analysis. No route is universally preferred; choices depend on consistent accounting and regional conditions.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本は水素・合成燃料（e-methanol等）をGX推進戦略の重点領域とし、海外再エネ由来水素・炭素源の調達と国内産業立地の両立が課題。本レビューは経路選択とTEA/LCA比較の枠組みを提供し、企業の脱炭素投資判断やGXリーグ・移行金融の議論に資する。
In the global GX context
Green methanol sits at the intersection of hydrogen strategy, CCU, and hard-to-abate shipping/chemicals decarbonization, and is increasingly referenced in transition-finance and ISSB-aligned climate strategies. The paper's call for consistent TEA/LCA boundaries and regional pathway selection speaks directly to global debates on credible transition claims and avoided greenwashing.
👥 読者別の含意
🔬研究者:TEA/LCAの比較可能性プロトコルと動的検証ギャップは、グリーンメタノール研究の方法論的基準として有用。
🏢実務担当者:自社のメタノール調達・e-methanol投資判断で、経路ごとのコスト・排出・供給条件を整理する枠組みとして活用できる。
🏛政策担当者:水素・合成燃料の支援設計や地域産業集積の条件整理に、経路選択マトリクスが参考になる。
📄 Abstract（原文）
Green methanol links low-carbon carbon sources with renewable electricity while retaining liquid-fuel handling advantages. We reviewed 155 publications covering genuinely green routes based on renewable hydrogen and sustainable carbon (CO 2 hydrogenation with renewable H 2 and biomass- or waste-derived methanol), transitional low-carbon retrofits of fossil-based plants, and less mature electrochemical, photocatalytic, or methane-conversion routes. Retrofits are treated as transitional, not genuinely green, because their carbon remains fossil-derived unless the feedstock is replaced. Authors adopt different system boundaries and functional units, and assumptions about electricity, CO 2 supply, plant scale, and cost are rarely identical. Our comparison places each pathway in its operating conditions and avoids ranking isolated performance values. It considers technical maturity, energy demand, life-cycle emissions, levelized methanol cost, feedstock supply, infrastructure, and operating flexibility, and examines when power-hydrogen-carbon integration is justified. The review provides four outputs: a protocol for checking the comparability of techno-economic assessment and life-cycle assessment (TEA/LCA) evidence, conditional rules for evaluating integration, a qualitative regional pathway-selection matrix, and a dynamic-validation gap analysis linking demonstrated performance to availability, load-following, capacity factor, and degradation. No route is universally preferred; a defensible choice depends on consistent accounting and on regional electricity, carbon resources, industrial assets, and end use. The integration comparison distinguishes H 2 -to-CO 2 power-to-methanol (PtM), H 2 -enhanced biomass/waste conversion, retrofit/carbon capture, utilization, and storage (CCUS) in fossil methanol hubs, and multi-source industrial symbiosis, and shows that no archetype is universally superior.
