バイオマスと再生可能電力からのグリーンメタノール生産の4経路を比較。水素統合ガス化は炭素利用92%、エネルギー効率54%を達成。ハイブリッド風力・太陽光下で全経路が欧州の低炭素燃料基準を下回る。再生可能電力が21ドル/MWh以下でコスト競争力を持つ。
English
This study compares four routes for green methanol production from biomass and renewable power, revealing trade-offs in carbon use, energy efficiency, emissions, and cost. Hydrogen-integrated gasification achieves 92% carbon utilization and 54% energy efficiency. Under hybrid wind-solar power, all routes meet EU low-carbon thresholds. Cost competitiveness emerges when renewable electricity falls below $21/MWh.

📄 Abstract（原文）
Green methanol could help decarbonize transport and industry, but its production roadmap remains uncertain because biomass conversion, renewable hydrogen supply, the emissions and cost of electricity are tightly coupled. Here we show, using pilot-scale gasification data and industrial process parameters, how four biomass- and renewable-power-based methanol routes differ in technical performance, life-cycle greenhouse gas emissions and production cost, and identify deployment-relevant boundary conditions. Gasification integrated with renewable hydrogen balances carbon utilization and energy efficiency, reaching 92% and 54%, respectively. Direct combustion followed by carbon dioxide hydrogenation raises carbon utilization to 96% but requires substantially more electrolysis-derived hydrogen. Under hybrid wind and solar power, all routes remain below the European low-carbon fuel threshold, although the maximum electricity emission factors compatible with this threshold vary from 0.057 to 0.373 kilograms of carbon dioxide equivalent per kilowatt-hour. Gasification without added hydrogen is currently the least-cost route. Hydrogen-integrated gasification approaches its cost when renewable electricity falls below US$21 per megawatt-hour, and approaches coal-based methanol costs at carbon prices of US$40-90 per tonne of carbon dioxide. These results define practical boundaries for route deployment. The study compares four routes for producing green methanol from biomass and renewable power, revealing trade-offs in carbon use, energy efficiency, emissions and cost, and identifying the deployment boundaries for each route.
