This article presents an analysis of the economic viability of developing projects for the capture and geological storage of carbon dioxide from the sugarcane ethanol production process, focusing on the State of São Paulo, where half of Brazilian production is concentrated. In it, the main technical aspects and cost factors for the development of CCS projects were analyzed, based on bibliographical research, consultation with producers and application of economic analysis techniques of Payback, NPV and IRR. The results of the analysis point to a condition of viability in the case of projects aimed at producing low-carbon Ethanol and sustainable aviation fuel, sold on the American market, which have access to monetization mechanisms, such as Low Carbon Fuel Standards of the State of California and 45Z incentive programs, respectively.
