CO2
• Production from CO2 EOR has increased 40% over the past 6 years
• In 2010 it was 5% of total domestic production
• EOR is the highest-value, highest-volume use of CO2
• EOR could potentially use CO2 from 60 GW of power plants with CCUS
• EOR will catalyze CCS technologies
while providing economic drivers
for commercial projects
Carbon Capture, Utilization and Storage (CCUS) through EOR is the Business Driver to Catalyze Continued Coal use for Power Generation
