GEOLOGIC CARBON SINKS Saline aquifers Oil and gas reservoirs Coal GOALS AND BENEFITS Reduce greenhouse gas emissions Develop market-based solutions Enhance oil and gas recovery Enhance coalbed methane recovery Create and preserve jobs
REGIONAL PARTNERSHIPS Hyman (2005)
PRINCIPAL SPONSOR U.S. Department of Energy - NETL PROGRAM TEAM SSEB, Virginia Tech - Contractual Geological Survey of AL - Tech Lead,Geology University of Alabama - Engineering Southern Company/EPRI - MMV Mississippi State University/ICET - MMV Univ. British Columbia - Analytical Oak Ridge National Laboratory - Analytical ARI - Reservoir Simulation CCP2 - Reservoir Modeling Denbury Resources - CO2
WHY COAL? CO2 capacity of 90 Gt (45 yrs) in US. CO2-ECBM potential of about 4.3 Tcm (150 Tcf) provides economic incentive. Shallow reservoir (150-1500 m) with low P&T can reduce compression cost Coal is abundant near major CO2 emission sources, such as power plants.
SECARB II OBJECTIVES Assess capacity/potential of geologic sinks (saline aquifers, O&G reservoirs, coal). Conduct field tests to validate sequestration and CO2-enhanced recovery technology. Conduct MMV programs to ensure safety, environmental protection. Conduct outreach/tech transfer to facilitate commercialization/public acceptance
