Capture of CO₂

The DOE's CO₂ capture efforts seek to transform the fossil-based portion of the U.S. energy system from its current configuration to one in which CO₂ can be captured safely and cost-effectively. Efforts to develop technologies to capture or separate CO₂ from a process stream are being undertaken in concert with efforts to develop advanced, highly-efficient fossil fuel conversion processes.

There are three fundamental fuel conversion platforms: (1) post-combustion; (2) pre-combustion; and (3) oxygen combustion. From the perspective of CO₂ capture, these three platforms offer different CO₂ partial pressures, different operating temperatures, and different components in the CO₂-rich stream. Capture technologies are being developed to fit into one or more fossil fuel conversion systems.
