Previous issue date: 2015-11-30 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior - CAPES / The contribution of anthropogenic emissions to the intensification of the greenhouse effect and consequent environmental change shows, once again, the need to find mitigation measures to the problem. In this context, the technology of Bioenergy with Carbon Capture and Geological Storage (BECCS) has emerged as a promising alternative for reducing emissions. BECCS projects are based on the concept of generating negative emissions by capturing CO2 from the biomass burning or processing, for example, for biofuel production, and storage in geological reservoirs. The implementation of such projects in Brazil is interesting due to two factors: a) the significant production of ethanol from biomass and b) the occurrence of extensive sedimentary basins with potential reservoirs for storage. This study aims to determine the potential to reduce Brazilian emissions through geological storage of carbon dioxide resulting from ethanol production. Thus, the source-sink matching methodology was applied using a Geographic Information System (GIS) with georeferenced data from stationary emission sources (ethanol plants), transport networks (pipelines) and storage sites (wells and sedimentary basins). In this way, it was possible to determine areas (clusters) with potential for deployment of BECCS projects, evaluating them in terms of volume of CO2 emissions (CO2 avoided potential). / A contribui??o das emiss?es antropog?nicas na intensifica??o do efeito estufa e consequentes altera??es ambientais evidencia, mais uma vez, a necessidade de se encontrar medidas de mitiga??o para o problema. Neste contexto, as tecnologias de captura e armazenamento de carbono com bioenergia (BECCS, do ingl?s Bioenergy with Carbon Capture and Geological Storage) surgem como uma alternativa promissora para a redu??o das emiss?es. Projetos de BECCS se baseiam no conceito de gerar emiss?es negativas por meio da captura do CO2 proveniente da queima ou processamento de biomassa, por exemplo, para produ??o de biocombust?vel, e posterior armazenamento em reservat?rio geol?gico. A aplica??o de projetos deste tipo no Brasil ? interessante devido a dois fatores: a) a significativa produ??o de etanol no pa?s a partir de biomassa e b) a extensa ocorr?ncia de bacias sedimentares com reservat?rios potenciais para armazenamento. O presente estudo se prop?e a determinar o potencial de redu??o das emiss?es brasileiras atrav?s do armazenamento geol?gico de di?xido de carbono resultante da produ??o de etanol. Para isso, foi aplicada a metodologia de associa??o fonte-reservat?rio (source-sink matching) utilizando um Sistema de Informa??es Geogr?ficas (SIG) com dados georreferenciados de fontes emissoras estacion?rias (plantas de etanol), redes/sistemas de transporte (dutos) e locais de armazenamento (po?os e bacias sedimentares). Desta forma foi poss?vel determinar ?reas com potencial para implanta??o de projetos de BECCS e avali?-las quanto ao potencial de emiss?es evitadas.
