6. Power Plant Capture Cost Estimating Challenges
• Power plant projects tend to have the highest cost for
incorporating CCSincorporating CCS
• The volume of information required to compile a complete
capital cost estimate is immensep
• Reference plant cost data is often limited for new
technologies
O f f• Owners are often in a rush to construct to take full
advantage of the project, including incentives, grants, etc.
• A firm design basis is critical to obtaining a good estimateA firm design basis is critical to obtaining a good estimate
• Many cost estimates are prepared before the scope is
finalized

7. Challenges for Retrofit Cost Estimates
• Integration into existing, operating power plant
Mi i i i d ti f ti i i iti l– Minimizing down time for tie-ins is critical
• Layout constraints often lead to higher costs
– Ducting, piping, and utility lines can be much longerg, p p g, y g
• There is no reference plant for most retrofits
– Every plant has unique features and requirements
• Existing emission control systems are often inadequate
– Especially for current solvent-based capture systems
• Need to work closely with plant operating staff during• Need to work closely with plant operating staff during
design phase
• Retrofit demo plants suffer poor economies of scale

8. R&D and Learn by Doing are Critical
• Both Research and Development (R&D) and learning-by-
doing play an important role in innovation and the cost ofdoing play an important role in innovation and the cost of
energy technologies in the marketplace
• If R&D is not performed, the cost is too high for most plants
to install technology or replace with new CCS facilities
– Learning-by-doing never gets off the ground
Sh i th l l d f l CCS d l t• Sharing the lessons learned from early CCS deployments
is essential for the long term success of carbon capture
• We need to develop a cost roadmap to get from first-of-a-e eed o de e op a cos oad ap o ge o s o a
kind (FOAK) to nth-of-a-kind (NOAK) costs
