Short summary
To combat global warming and achieve net-zero CO2 emissions by 2050, Carbon Capture and Storage (CCS) is vital. Despite being a top CO2 emitter globally, Brazil is early in its CCS journey. Our study evaluates the potential of using southern Brazil's saline aquifers for CO2 storage with the aim of supporting Brazil’s efforts to reduce emissions and mitigate climate change. We identify optimal storage sites in two basins, Paraná and Espírito Santo, with ideal locations near existing pipelines.
