探索实现三十亿加仑可持续航空燃料的原料路径：合同与生物能源作物保险的作用
Exploring Feedstock Pathways to Three Billion Gallons of Sustainable Aviation Fuel: The Roles of Contracts and Bioenergy Crop Insurance
摘要
This study examines how contracts and bioenergy crop yield insurance incentivize biomass supply for three billion gallons of sustainable aviation fuel. Results show that meeting feedstock demand by growing uninsured miscanthus requires a fixed biomass price at $78–$86/metric ton, a revenue share of 32%–36%, or a land‐leasing payment about $178/acre. Growing uninsured switchgrass requires similar terms. Bioenergy crop insurance partially substitutes for compensation for bearing production risk, decreasing required fixed prices and revenue shares by 4% (6%) for miscanthus (switchgrass), while having minimal impact on bioenergy crop acreage and average biomass production cost, but mixed effects on farmers' welfare gains.
中文摘要
本研究考察了合同与生物能源作物产量保险如何激励为30亿加仑可持续航空燃料供应生物质。结果表明，通过种植未投保的芒草来满足原料需求，需要将生物质固定价格设定为每公吨78–86美元、收入分成比例为32%–36%，或土地租赁付款约为每英亩178美元。种植未投保的柳枝稷需要类似条件。生物能源作物保险部分替代了对承担生产风险的补偿，使芒草（柳枝稷）所需的固定价格和收入分成比例降低4%（6%），同时对生物能源作物种植面积和平均生物质生产成本影响甚微，但对农民福利收益的影响则好坏参半。
