Carbon Capture and Geological Storage - technologies, risk analysis and prospects for use in Brazil

The burning of fossil fuels for electricity generation is now the main source of emissions of GreenHouse Gases (GHG). Moreover, during the extraction of oil and gas, an amount of CO₂ is carried to the surface, and released into the atmosphere. As the concentration of CO₂ in the pre-salt deposits is higher than in wells currently operated, emissions growth will occur not only by the expected growth in production volume. An alternative to prevent these releases is to reinject the carbon in the reservoir from which it was extracted or in other geological formations nearby. All stages of Carbon Capture and Geological Storage were analyzed from separation up to monitoring. The assessment of associated risks, as well as aspects of policy, regulation and prospects for use in Brazil was analyzed.
