​​​Carbon Capture and Storage  (CCS) is one of the tools available to mitigate emissions from thermoelectric power plants.

The Brazilian energy matrix has a percentage of coal fueled thermoelectric power plants generation of about 1.5% of the energy generated. The difficulty to build hydroelectric power plants with regulating reservoirs and energy security require a diversified en​ergy matrix which inevitably means further exploiting the potential of coal fueled thermoelectric power plants.

Since February 2010, COPPE/UFRJ has been providing technical advice to ENEVA on the survey of state of the art means to Capture and Store Carbon from coal fueled thermoelectric power plants.

The work includes surveying of the most appropriate technologies for application in Brazil, considering three steps:

- Burning coal technology;

- Surveying techniques for capturing carbon dioxide (CO2);

- Transport and storage of CO2 to sinks (such as geological formations, oceans and carbonate minerals).

    Through a partnership between ENEVA and the Centro China-Brasil, COPPE / UFRJ technicians are closely assessing the Chinese plants currently in operation, or in design phase, involving the use of CCS techniques. This study is likely to be extended to assessing the work currently in progress in Europe centers, especially in Germany.

    COPPE studies have a 21 month completion timeframe and are expected to propose in the end a CCS technology demonstration project.
