GeoFile 2003-11: CO2 Sequestration
View GeoFile (PDF, 2.25 MB)
New and affordable ways to trap CO2 gas in a permanent way are currently being investigated as a result of Kyoto commitments. BC currently emits 65.9 Mt/tear CO2, of which some 82.4 per cent are the result of burning fuels for energy.
CO2 can be trapped in deep saline aquifers or hydrocarbon reservoirs which are found within sedimentary basins in NE and central BC as well as Vancouver Island. Coal beds that can trap CO2 gas are near some point source emitters in southeast and south-central British Columbia as well as Vancouver Island. Ultramafic rocks can trap CO2 by converting magnesium silicates to magnesite and quartz. Cost factors are poorly known but include the concentration of CO2 in the emitted gas, the distance from source to sink, the infrastructure in place to transport and deliver CO2 gas, and the actual cost of sequestering the CO2 gas.
