Capture Technology Supply Curve
Total cost per tonne of CO2 abated ranges from $70 to $250 depending heavily on the capture process and CO2 source. What is evident is that there are several key thresholds at which significant volumes of CO2 become available, as highlighted in the table and graph below.
1 |
$70 -$90/t | At this range it becomes feasible to capture CO2 from gasification plants used to produce hydrogen for petroleum upgraders. |
2 |
$90 – $120/t | This includes capture from existing chemical fertilizer plants. |
3 |
$120 – 160/t | This range includes retrofitting steam methane reformers for hydrogen manufacturing. |
4 |
$90 – $120/t | This includes capture from new coal-fired generation plants. |
5 |
$120 – 160/t | This represents capturable volumes from new steam methane reforming (SMR) units such as those typically found at refineries and upgraders. |
6 |
$160 – $250/t | These numbers include new and retrofit natural gas flue stacks and other power generation systems in addition to steam-assisted gravity drainage (SAGD) operations. |
Despite the relatively high costs, as Carbon Capture and Storage begins to develop, the cost of technology will decrease.
