Regional carbon capture and storage opportunities in Alberta, Canada.

• Alberta's CO 2 emission from the power and industry sectors is 136 Mtpa. • The total mid CO 2 storage capacity in oil and gas fields in Alberta is 5.2 Gt. • A CCS corridor within 200 km from Edmonton is proposed which will mitigate up to 52 Mtpa CO 2 or 38% of Alberta's CO 2 emission. To enable Alberta, Canada to reduce CO 2 emissions by 30% from 2005 levels by 2030, we investigate carbon capture and storage (CCS) opportunities in Alberta, Canada by conducting a plant-by-plant evaluation of CO 2 emissions from 157 power and industrial plants and a field-by-field analysis of CO 2 storage capacity in 15,143 oil fields and 68,327 gas fields. Results show that CO 2 emissions from power and industrial plants is 136 Mtpa. Additionally, the mid CO 2 storage capacity is 41.5 Gt in gas fields and 5.2 Gt in oil fields. Oil fields also have a mid CO 2 -enhanced oil recovery (CO 2 -EOR) potential of 6,895 MMbbl. Based on these findings, this paper proposes a first-of-a-kind CCS corridor within 200 km from Edmonton, which can mitigate up to 52.4 Mtpa CO 2 or 38% of Alberta's emissions from power and industry sectors. There is a mid CO 2 storage capacity of 1.8 Gt and mid CO 2 -EOR potential of 3,550 MMbbl within this CCS corridor. [ABSTRACT FROM AUTHOR]
