    Abstract 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 CO 2 produced during the alcoholic fermentation process and the potential to store and use the CO 2 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 CO 2 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 CO 2 . The road modal choice cut-off range applies to distilleries with a CO 2 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. Highlights This work developed and applied a methodology to design an optimal sugarcane ethanol bio-CCS CO 2 network. Alternative network concepts were proposed: one-hub and pipelines, inter-modal network and a multiple-hub system. For the reference case, 72 out of the 236 distilleries opted for the road modal connection to the hub. Distilleries with a CO 2 production below 150 kt/yr and farther than 300 km from the hub tend to choose roads over pipelines.
