2011-12 EPRI IGCC R&D Roadmap Update

Selecting a Path


2011-12 EPRI IGCC R&D Roadmap Update EPRI CoalFleet Activities

• Write an update report (1022035 - October 2011) • Re-engage EPRI RD&D working group • Review related RD&D plans and discuss appropriate

alignment • Prioritize technologies for due diligence

• Identify new opportunities for

– Engagement – Collaboration – Co-sponsorship


2011-12 EPRI IGCC R&D Roadmap Update Roadmap Update Report

• Updates on technologies from 2007 report (1013219)

• Compilation of recent EPRI roadmap study results

• Summary of CCPC IGCC advanced tech evaluations

• Summary of related roadmaps

• 1022035 scheduled for

publication in October

• Publicly available (no cost)


2011-12 EPRI IGCC R&D Roadmap Update General Approach

• Gather and organize development ideas

• Identify evaluation criteria • Identify goals • Pre-screen

• Prioritize • Perform due diligence

– Technology Briefing Documents

• Engage


2011-12 IGCC EPRI R&D Roadmap Update Technology Development Table

• 64 technology development ideas generated • Organized by plant area (with 1 cross-cutting category) • Used as a starting point for the evaluation & prioritization

process

Oxygen Production: 3

Gasification Island: 15

Syngas & CO2 Processing: 14

Power Block: 16

Balance of Plant: 8

Plant-wide Improvements: 8

Actively Seeking New Ideas for Roadmap Consideration


2011-12 IGCC R&D Roadmap Update Goal-Setting: Key Time Frames

Near-Term: 2015 • Focus on cost reduction and base plant performance • Natural gas combined cycle-equivalent CO2 emissions

Mid-Term: 2025 • Focus on CCS cost reduction and operational flexibility • Full CO2 capture

Long-Term: 2035 • Focus on advanced performance and

Lowest COE (all coal ranks)

IGCC CCS Technology Roadmap Due Diligence: Example of Technology Briefing Document

2-Page Briefing Document Used to Educate, Align, and Plan


Closing Thoughts

• Studies show significant potential for IGCC plant cost and performance improvement

• Evaluating and prioritizing R&D efforts is critical given limited research funding

• EPRI is seeking to actively engage and collaborate with the industry
