<b>Abstract<br>
</b>Studies of CO2 capture and storage (CCS) costs necessarily employ
a host of technical and economic assumptions regarding the technology
or system of interest, including details of the capture technology
design, the power plant and gas stream being treated, and the methods
of CO2 transport and storage. The specific assumptions employed
can significantly affect the results of an analysis; hence, published
studies may be of limited value to researchers seeking results for
alternative assumptions or plant characteristics. This
presentation first reviews recent CCS cost studies for pulverized coal
(PC), natural gas combined cycle (NGCC), and integrated gasification
combined cycle (IGCC) power plants. A generalized modeling tool
is then used to systematically estimate and compare the emissions,
efficiency, resource requirements and costs of PC, IGCC and NGCC
plants across a broader range of parameters than found in recent
studies. In particular, the effects of higher natural gas
prices, variations in coal quality, and differential plant utilization
rates are explored, along with the implications of financing and
operating assumptions for IGCC plants. The impact of CCS energy
requirements on plant-level resource requirements and multi-media
environmental emissions also is highlighted and quantified.
Finally, the potential for future cost reductions is examined in the
context of ongoing R&D programs and government policies related to
global climate change.</font><br>
