Captation du carbone concentré

The document identifies concentrated carbon capture as a "safe bet" for industrial processes with high-concentration CO2 streams, such as cement and ammonia production, while categorizing non-concentrated applications (e.g., natural gas power) as "risky bets." It highlights the technology's potential role in Canada's net-zero pathways, noting that while it could reduce oil and gas emissions by 17 to 50 megatonnes by 2030, its large-scale deployment depends on long-term policy certainty and government financial support, including investment tax credits.

• Concentrated carbon capture is considered a "safe bet" when applied to point sources with constant, high-concentration CO2 streams, whereas capturing carbon from non-concentrated sources like natural gas combustion or direct air capture are "risky bets."
• In Canada, concentrated carbon capture could significantly impact the oil and gas sector, potentially reducing emissions by 17 to 50 megatonnes by 2030. Long-term modeling suggests it could represent between 1% and 29% of all emissions reductions by 2050.
• The technology is commercially viable for a subset of large emitters, with costs ranging from $80 to $300 per tonne depending on CO2 concentration. In the Canadian oil sands, only 8% of emissions to be reduced are currently concentrated enough to be potentially viable; the remaining 49% of low-concentration emissions would require a carbon price of at least $170 per tonne.
• Deployment is hindered by high capital and operating costs, energy intensity, and the need for custom engineering for each facility, with the capture component accounting for 80% of total costs. Consequently, investor confidence relies on policy stability, such as the federal investment tax credit covering up to 50% of costs.
