Operational Flexibility of CO 2 Transport and Storage

Carbon dioxide (CO2) is produced in large quantities during electricity generation and by industrial processes and can vary in composition and mass flow rate, sometimes substantially. This project identified the extent of the technical challenges posed by CO2 stream variability on transport and storage operability and infrastructure robustness. The U.S. enhanced oil recovery industry has shown that maintenance of CO2 stream composition standards avoids issues with impurities and that it is possible to adapt to variability and intermittency in CO2 supply. Such CO2 transport and injection experience represents knowledge that can be applied in future carbon capture and storage projects.
