Strategy
 License or own CO2 capture plants,
 retrofitted to coal and gas fired power
 plants
 Will finance, construct and manage based
 on long term contracted off-taker of CO2
 Preference is to own the plant (as a speed-
 to-market tool)
 Initially license to establish a beachhead

CO2 Capture Study
for:

   Capture of 85% of the total flue gas from the 420 MW power
 plant with strict performance guarantees.
   The required operating range of the CO2 capture plant is
 between 60 – 100% of the total plant flue gas capacity.
   It is required to evaluate the effects of varying the CO2 capture
 rate between 80 and 90%.
   The captured CO2 is liquefied for pump out for EOR
 applications.

CO2 Sinks in Nova Scotia

Natural gas and oil fields
Saline aquifers
Onshore and offshore coal formations
Salt domes ?
   Potential Large Uses For CO2
EOR/ EGR/ECBM
Depleted Oil and Gas Reservoirs
Geology is well understood
Oil and gas been stored for a long time
Good sites for CO2 storage
Deep Saline Aquifers
Deep salt water-saturated rock formations
Geology and effect of the CO2 on these aquifers is not yet well
understood and more research is needed
Deep Unmineable Coal Seams
CO2 can be held in the pores on the coal surface and in fractures.
Forces methane from the coal beds which can be used as fuel.
Transportation by vessel
Methanogenesis
Research and Development Needs
Research needs to be aimed at developing the ability to characterize a
formation before CO2 injection so as to predict its storage capacity.
Injection techniques to achieve broad dispersion of CO2 throughout the
formation, overcome low diffusion rates, and avoid fracturing cap rock.
Risk assessment and screening.
Technologies for monitoring and verification of integrity of CO2 sequestration.
Develop formation sealing technologies.
Underground (in situ) coal gasification.
Methanogenesis closed-loop” fossil fuel carbon cycle process.
