This fact sheet describes oxyfuel combustion, the technology that burns fuel in almost pure oxygen. Because this makes it easier to capture carbon dioxide from flue gas, it may be possible to achieve near zero carbon dioxide emissions from the production of coal fired electricity. A diagram illustrating this process is included as well as a brief description of a new project aiming to integrate oxyfuel combustion with carbon capture and sequestration.
