【摘要】 在“双碳”战略驱动下，绿色甲醇作为氢基能源载体与绿电消纳的关键媒介，其规模化制备技术已成为能源转型的重要途径之一。基于此，提出一种计及生物质富氧燃烧碳捕集的风光氢醇系统，以系统年收益最大化为目标，利用混合整数线性规划模型实现设备容量配置与仿真调度优化。结果表明：案例10万吨级零碳甲醇工厂经过容量配置与运行调度协同优化后，实现可再生能源发电、生物质富氧燃烧碳捕集、电解水制氢、甲醇合成各工段的协同运行，以近零碳排放的形式生产绿色甲醇。新型系统所生产的零碳甲醇平准化成本为4596 CNY/t，可再生能源弃电率7.9%，能够实现可再生发电的有效消纳并具有一定的经济可行性。此外，还进行了关键设备、生物质燃料与甲醇成本间的敏感性分析。研究结果为推动绿色甲醇产业发展提供了参考依据。更多还原

【Abstract】 Driven by the “Dual-Carbon” strategic objectives, green methanol has emerged as a critical hydrogen-based energy carrier and a key medium for renewable electricity utilization. Its large-scale production technology has become a pivotal pathway for energy transition. This study proposes an integrated wind-solar-hydrogen-methanol system incorporating biomass oxy-fuel combustion carbon capture. Aiming to maximize annual system revenue, a mixed-integer linear programming(MILP) model is developed to co-optimize equipment capacity allocation and operational dispatch. Case study results demonstrate that a 100000-ton zero-carbon methanol plant achieves coordinated operation across renewable power generation, biomass oxy-fuel carbon capture, water electrolysis hydrogen production, and methanol synthesis processes through capacity-dispatch cooptimization, producing green methanol with near-zero carbon emissions. The levelized cost of zero-carbon methanol in the proposed system reaches CNY 4596 per ton, accompanied by a 7.9%renewable energy curtailment rate, indicating effective renewable power integration and economic viability. Sensitivity analyses further reveal the impacts of key equipment parameters, biomass fuel prices, and methanol market prices. These findings provide actionable insights for advancing the green methanol industry.更多还原
