Deployment of bioenergy with CO₂ capture and storage (BECCS) is projected to be crucial in reducing the United States’ CO₂ emissions intensity. In this paper, we utilize a spatially explicit costing model to evaluate how regional biophysical factors and geography affect BECCS viability. We find that the cost of biomass provision and CO₂ transport and storage are an average of $20/t‐CO₂ and $16/t‐CO₂ for aquatic and terrestrial BECCS, respectively. Assuming rapid technological development in the CO₂ capture domain, this corresponds to 40–72% of land area in the conterminous United States exhibiting systems integration costs compatible with 2030 carbon prices (median $90/t‐CO₂). Results are strongly influenced by the cost of geologic sequestration, in particular storage quality (as driven by depth, permeability, etc.) and available capacity, rather than simply proximity to nearby CO₂ sources. For this reason, the Southeast presents appealing BECCS readiness owing to high biomass productivity (several counties with yield >100 000 dry ton of biomass per year) interspersed with well‐explored sinks with large sequestration potential and optimal reservoir quality with permeability >500 mD. We also find that geologic storage capacity is unlikely to be a major biophysical constraint, as sink utilization in most states would likely remain below 10% at the projected rates of BECCS deployment to achieve the 2 °C target and as low as 1% in Texas, Oklahoma, and Alabama. The analysis also reveals subtle secondary outcomes; for example, to what extent different regions may be well poised to adopt different, complementary negative emissions technologies based on specific confluences of circumstances. © 2020 Society of Chemical Industry and John Wiley & Sons, Ltd.

解释运输和存储基础设施成本在碳负生物能源部署中的作用

预计通过CO ₂捕集与封存（BECCS）部署生物能源对于降低美国的CO ₂排放强度至关重要。在本文中，我们利用空间明确的成本模型来评估区域生物物理因素和地理环境如何影响BECCS的生存能力。我们发现，水生和陆生BECCS的生物质提供成本以及CO _2的运输和存储成本分别平均为$ 20 / t-CO ₂和$ 16 / t-CO ₂。假设在CO ₂捕集领域技术发展迅速，这相当于美国本土40-72％的土地展示系统集成成本与2030年碳价相当（中位数为$ 90 / t-CO₂）。结果受到地质封存成本（尤其是存储质量（由深度，渗透率等驱动）和可用容量）的强烈影响，而不是简单地靠近附近的CO ₂资料来源。由于这个原因，东南部由于生物质生产率高（几个县/年的生物质产量超过100000干燥吨/年）而备受瞩目的BECCS准备就绪，并穿插了开发良好的水库，具有大的固存潜力和最佳的储层质量，渗透率> 500 mD。我们还发现，地质存储容量不太可能成为主要的生物物理限制，因为在大多数州，以BECCS部署的预计速率实现2°C目标的水槽利用率可能保持在10％以下，而在德克萨斯州则低至1％ ，俄克拉荷马州和阿拉巴马州。分析还显示出细微的次要结果。例如，根据具体情况的融合，不同地区在多大程度上准备采用不同的互补性负排放技术。
