The project objective is to demonstrate the concept of the second generation oxyfuel combustion that reduce significantly (50%) the overall efficiency penalty of CO2 capture into power plants, from approximately 12 to 6 efficiency points.One of the main drawbacks of CCS is the additional energy used for operation. This energetic penalty reduces the power plant efficiency, and increases the cost of ...

This project combines the CFB’s intrinsic advantages (fuel flexibility and low emissions) with oxygen-firing for carbon capture and storage (CCS). In oxygen-firing systems the fuel is burned in a mixture of pure O2 and recirculated flue gas instead of air. The absence of air nitrogen produces a flue gas stream with a high concentration of CO2, making it much easier to separate the CO2. CFB technol ...
