EPRI has an on-going effort to understand the landscape of postcombustion CO2 capture technologies globally, and accelerate their development. Several central issues facing CO2 capture involving scale, energy, and overall status of development will be discussed. We show that the scale of CO2 emissions is sufficiently large to place inherent limits on the types of capture processes that could be deployed broadly. We also discuss the minimum energy usage in terms of a parasitic load on a power plant and we present summary findings of the landscape of capture technologies using an index of technology readiness levels.
