本論文は、中国のカーボンニュートラル目標達成に向けたグリーンメタノール生産の経済性を分析。再生可能水素とガス化の統合システムで生産コスト454-510ドル/トン、CCS付きガス化のみで445-450ドル/トンと試算。温室効果ガス排出削減率は98.2-124.7%に達し、炭素クレジットが価格競争力の鍵と示唆。2060年までにコストが51-94%削減可能とし、戦略的バイオマス配分で年間3700-4400万トンのCO2排出削減を見込む。
English
This study analyzes the economic viability of green methanol production from biomass in China to support carbon neutrality by 2060. Integrated renewable hydrogen-gasification systems achieve production costs of $454-510/MT, while gasification-only with CCS reaches $445-450/MT. GHG emission reductions of 98.2-124.7% are possible, with carbon credits critical for cost parity. Cost reductions of 51-94% by 2060 are projected, and strategic biomass allocation could reduce 37-44 MtCO2/year from marine fuel.

日本のGX文脈において
中国のカーボンニュートラル政策と連動したグリーンメタノールの経済性分析は、日本でもCCSや水素活用の参考となる。特に、バイオマス資源の地域配分や炭素クレジットの活用戦略は、日本のGX政策におけるバイオマス利活用やe-fuel導入検討に示唆を与える。
In the global GX context
This paper provides detailed economic modeling of green methanol production with CCS and hydrogen integration, relevant to global decarbonization pathways for hard-to-abate sectors like shipping. The regional deployment analysis and carbon credit sensitivity offer insights for countries evaluating biomass-based fuels under carbon pricing regimes. The cost reduction projections align with global energy transition scenarios.

📄 Abstract（原文）
<p>To confront the dual challenges of energy security and ambitious carbon neutrality goals by <styled-content style-type="number">2060</styled-content>, green methanol projects are being prioritized as critical solutions for decarbonization in China. In this study, renewable hydrogen-integrated gasification systems were shown to achieve production costs in the range 454 – 510 <inline-formula><tex-math id="M1">${\$}$</tex-math></inline-formula>/MT in the best-performing provinces in the northeastern regions. However, gasification-only systems coupled with carbon capture and storage under a grid power regime achieve even lower costs, 445-450 <inline-formula><tex-math id="M2">$ {\$}$</tex-math></inline-formula>/MT. Compared to fossil methanol, biomass-based methanol systems can achieve GHG emission reductions of 98.2-124.7%, avoiding 335-522 ktCO<sub>2</sub>-eq/yr. Carbon credit incentives will be critical in achieving cost parity with conventional methanol, as lower carbon prices currently favor hydrogen-integrated systems using variable renewable energy. Under aggressive decarbonization policies, cost reductions of 51-94% by <styled-content style-type="number">2060</styled-content> can be achieved. Strategic biomass allocation could satisfy China's marine fuel demand while preventing 37-44 million tons CO<sub>2</sub> emissions annually.</p>
