風力・太陽光による水電解水素とバイオマスガス化を組み合わせたグリーンメタノール合成の統合技術ルートを提案。内モンゴルの実証プロジェクトを対象に、バイオマスガス化ガスのバイパス系統を設けることで設備投資の小幅増のみで年間メタノール生産量を約20%増加できることを示した。最適な再エネ設備容量は660MW、水素製造規模7万Nm3/h、年間メタノール生産32万トン、再エネ総合利用率95.19%と試算。税引後IRR8%で経済的に成立し、炭素削減効果も大きいと結論づける。

📄 Abstract（原文）
To realize efficient on-site consumption of renewable energy such as wind power and photovoltaic power, this paper proposes an integrated technical route for synthesizing green methanol by combining wind-solar hydrogen production with biomass gasification. It outlines the specific technical paths of alkaline water electrolysis hydrogen production, fixed-bed biomass gasification and low-pressure methanol synthesis, and systematically elaborates the complete process flow from renewable energy power generation to green methanol distillation. Taking a demonstration project in Inner Mongolia as the research object, a full-process process system of "wind-PV—electrolytic hydrogen production—hydrogen storage—biomass gasification—coupling of gasification mixture with green hydrogen—syngas methanol synthesis—hydrogen recovery" is constructed, and system capacity optimization matching is completed using the real-time power balance method. Due to the large volatility of wind and solar energy, this research innovates the system operation matching and sets a bypass for biomass gasification mixture delivery as a backup system. With only a small increase in equipment investment, the annual methanol output can be increased by approximately 20%. The results show that the optimal renewable energy installed capacity of the project is 660 MW (590 MW wind power, 70 MW photovoltaic), the hydrogen production scale is 70,000 Nm3/h, the effective hydrogen storage scale is 95,000 Nm3, and the annual production capacity of green methanol is 320,000 tons; the comprehensive utilization rate of renewable energy reaches 95.19%. Based on the post-tax financial internal rate of return of 8%, the tax-inclusive selling price of green methanol is 4,878.43 CNY/ton, and the project is economically feasible with significant carbon emission reduction benefits. This scheme can realize flexible collaboration of source-grid-load-storage and provide engineering demonstration and reference for similar domestic green methanol projects in China.
