According to the Kyoto Protocol, planning an ecologically sustainable future is the greatest challenge of the 21st Century. Current patterns of energy resources and energy use are shown detrimental to the welfare of mankind in the long run. The integrity of essential natural systems is already at risk because of the climate change caused by the intense emission of greenhouse gases into the atmosphere. In this context, the Carbon Capture and Storage (CCS) technology is a promising activity that aims to reduce the emission of gases responsible by the greenhouse effect and climate change mitigation through CO2 capture, transport and storage in suitable geological formations (saline aquifers, coal reservoirs, oil and gas reservoirs). Therefore, inserted in this context, this dissertation has how objective analysis of the technical potential for carbon capture and geological sequestration of Espírito Santo onshore and offshore basin addressing amenable geologic environments to the application of CCS projects, phases that make up these projects, their investments and operational costs and the development of mathematical modeling for the calculations regarding the storage capability and calculation of estimated financial profitability along with its execution through the sale of extra oil produced by the advanced recovery technique of oil and the sale of carbon credits. For that, this project had how methodological strategy: the exploratory research and review of the literature on the subject, the collection of secondary data, via document analysis, and xx collecting primary data via interviews with experts and participation in national and international congress geared for the theme. Therefore, it is concluded that CCS projects are possible deployment in the state of Espírito Santo, this is because in addition to the geological structure of oil and gas reservoirs in the Espírito Santo basin contribute to good results (as, in most cases, are sandstone reservoirs with presence of seal rock), the potential of saline aquifers and the potential of hydrocarbon fields studied in this dissertation (Golfinho, Inhambú, Fazenda Alegre, Cação, Canapu, Cangoá, Peroá and Camarupim) deserve national recognition; however, the lack of maturity of the private and public sectors, with respect to the management of projects of this nature and their widespread use, prevents the advancement of such technologies in the state of Espírito Santo and therefore in Brazil.
