PROJECT OVERVIEW
This project will estimate EGS life cycle
costs and analyze key cost drivers
Project Objectives
1. Independent estimates of the current cost structure of EGS
2. Estimate costs impacts of new technologies and market issues
3. Insight into the state of EGS technology through patent analytics
4. Evaluation of novel process configurations, e.g., CO2-EGS-IGCC
5. Outreach in industry, academia, and community to disseminate findings
Tackles DOE GTO Barriers
Limited policy analyses
Lack of datasets / models
Unclear economic benefits
Lack of integrated analyses
Unknown infrastructure impacts
Supports DOE GTO Goals
Assess likelihood of achieving EGS goals
Estimate EGS technology readiness
Evaluate cost impacts of new tools and
technologies from DOE GTO R&D
