CCS: A Technical Overview and its Perspectives in Brazil

The present work will address, among other aspects, the technical context, history, and importance of the use of CCS in the current world situation. The use of this technology is highlighted as a search for technological solutions to reduce greenhouse gas emissions and consequent mitigation of global warming. The history and motivators of the use of technology and its challenges faced over the years will be objects of study, as well as the storage facilities will be described, classifying them by their storage capacity, its operational status, the development of new facilities projects as well as critical analysis regarding the use of these facilities in countries such as the United States, Canada, Australia, Norway, Saudi Arabia, China, and Brazil, using the latest data from specialized entities and agencies, such as the International Energy Agency (IEA) and the Global CCS Institute. In the end, there is a description through a literature review of the methodology used for the technical evaluation of reservoirs conducive to carbon dioxide storage using the Brazilian case study.
