Triagem de Clusters e Hubs Industriais de CCUS no Nordeste Brasileiro por Análise de Dados Geoespaciais

Abstract

The injection and permanent storage of CO2 are critical operations in the Carbon Capture, Utilization, and Storage (CCUS) chain, essential for osetting emissions in hard-to-abate sectors such as energy and industry. Brazil’s Northeast region—particularly the states of Bahia (BA), Rio Grande do Norte (RN), Sergipe (SE), and Alagoas (AL) oers a highly favorable scenario for CCUS implementation due to its concentration of industrial hubs, existing oil well infrastructure in highly prospective sedimentary basins, and strategic logistics. This study identies CCUS clusters and hubs in these states using opportunity metrics based on emission density, transport feasibility, and the reuse of wells with an opportunity index (Ow) greater than 0.3 as CO2 sinks. The Potiguar (RN), Recôncavo (BA), and Sergipe-Alagoas (SE/AL) basins were analyzed, selected for their proven storage capacity. The methodology included mathematical models for screening municipalities by emissions and geospatial analysis. This study contributes to the assessment of the feasibility of scalable geological carbon storage projects in the Northeast, highlighting the integration of legacy infrastructure with new economic opportunities for the oil and gas sector.
