The growing importance of negative emission technologies in the energy sector for a “well-below 2 °C” world by 2100 seems to be a great opportunity for biological carbon capture and storage (BECCS) in the Brazilian sugarcane ethanol industry, given the low capture costs of the CO₂ produced during the alcoholic fermentation process and the potential to store and use the CO₂ for Enhanced Oil Recovery (EOR) in mature oil fields in the country. Notwithstanding, previous scientific studies indicated high transport infrastructure costs as a major constraint for the economic feasibility of exploiting this potential. This work developed and applied a methodology to design an optimal sugarcane ethanol BECCS CO₂ network (the baseline) together with two alternative concepts: one considering an inter-modal network of road and pipeline transport and another with a multiple-hub system. The results for the system’s abatement costs, including sensitivity analyses for the best- and worst-case scenarios, ranged between 32 and 87 US$/t of CO₂. The road modal choice cut-off range applies to distilleries with a CO₂ annual production under 150–200 kt and further than 250–300 km from the hub. For the reference case, 70 out of the 236 distilleries opted for the road modal connection to the hub.

到2100年，负排放技术在能源行业中对“低于2°C的世界”的重要性日益提高，这似乎是巴西甘蔗乙醇行业生物碳捕集与封存（BECCS）的绝好机会酒精发酵过程中产生的CO _2的成本，以及在该国成熟油田中储存和使用CO ₂以提高采收率（EOR）的潜力。尽管如此，以前的科学研究表明，高昂的运输基础设施成本是开发这种潜力的经济可行性的主要制约因素。这项工作开发并应用了一种方法来设计最佳的甘蔗乙醇BECCS CO ₂网络（基线）以及两个替代概念：一个考虑公路和管道运输的联运网络，另一个考虑多枢纽系统。系统减排成本的结果（包括最佳和最坏情况的敏感性分析）在32至87美元/吨CO _2之间。道路模式选择的截止范围适用于年产CO ₂低于150–200 kt且距枢纽距离超过250–300 km的酒厂。对于参考案例，在236个酿酒厂中，有70个选择了与集线器的公路联运。
