George Booras, EPRI - Power plant capture case studies - Introduction

  1. 1. Session 3: Power Plant Capture: Case StudiesPower Plant Capture: Case Studies George Booras (gbooras@epri.com) Senior Project Manager CCS Cost Workshop International Energy Agency, Paris, France November 6-7, 2013
  2. 2. Session 3 Overview This session will focus on cost estimates for CCS applications in electric power generation including:applications in electric power generation, including: • Retrofits • Gas-fired generationGas fired generation • Demonstration plants under construction The speakers for this session are: • Des Dillon (EPRI) • Wilfried Maas (Shell) • Max Ball (Saskpower, Web Presentation) 2© 2013 Electric Power Research Institute, Inc.

Understanding Cost Growth as a Function of Engineering Detail for New Technologiesg g g Detailed Preliminary Detailed Frequency Simplified of Occurrence • For many new technologies the cost estimates increase in value as they become more accurate Cost 4© 2013 Electric Power Research Institute, Inc.

  6. 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 6© 2013 Electric Power Research Institute, Inc.

  7. 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 7© 2013 Electric Power Research Institute, Inc.

  8. 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 8© 2013 Electric Power Research Institute, Inc.
