本文利用碳导航系统 (CNS) 模型，探讨了生物能源碳捕获与封存 (BECCS) 设施选址对三个案例研究供应链碳排放绩效的影响。三个案例研究供应链分别是麦秆衍生的 BECCS 电力、城市固体废物衍生的 BECCS 垃圾发电以及锯木厂残渣衍生的 BECCS 氢气。 BECCS 设施需要仔细选址，考虑当地的低碳基础设施、可用的生物质和地理位置，以便成功部署并实现有利的净负碳平衡。平均而言，在三个供应链中，BECCS 设施选址每移动 10 公里，就会导致空间显性供应链排放量增加 8.6-13.1%。以高产率生产低纯度二氧化碳的 BECCS 设施位于产业集群内时，其空间排放量较低，而以低产率生产高纯度二氧化碳的设施在集群外表现更好。还生成了一张地图，以确定三个模型供应链中哪一个为英国任何给定区域以 1 MtCO2/年的捕获规模提供了最低的空间明确供应链排放选项。
This paper explores the implications of siting a bioenergy with carbon capture and storage (BECCS) facility to carbon emission performances for three case-study supply chains using the Carbon Navigation System (CNS) model. The three case-study supply chains are a wheat straw derived BECCS-power, a municipal solid waste derived BECCS-waste-to-energy and a sawmill residue derived BECCS-hydrogen. A BECCS facility needs to be carefully sited, taking into consideration its local low carbon infrastructure, available biomass and geography for successful deployment and achieving a favorable net-negative carbon balance. On average, across the three supply chains a 10 km shift in the siting of the BECCS facility results in an 8.6–13.1% increase in spatially explicit supply chain emissions. BECCS facilities producing low purity CO2 at high yields have lower spatial emissions when located within the industrial clusters, while those producing high purity CO2 at low yields perform better outside the clusters. A map is also generated identifying which of the three modeled supply chains delivers the lowest spatially explicit supply chain emission options for any given area of the UK at a 1 MtCO2/yr capture scale.
