Canada's CO2 Capture and Storage TRM 
Technology Pathways

Table of Contents for this "Technology Pathways" Section


The overarching technology pathway often discussed regarding CCS is in actual fact a combination of many pathways that converge around the common goal of CO2 capture and long-term storage. These pathways each relate to one of the three necessary components: capture and compression, transport and storage. Each component is essential for the development and deployment of fully commercial CCS infrastructure and systems in Canada.

Although each component has its own technical focus and set of goals and objectives, it is important to study the integrated system because all three components are essential to it. After all, the technological success of capture and transport will not matter if storage cannot be proven technically feasible.

Therefore, this section provides a description of each component or technology area in terms of specific technologies and potential applications. The current costs of these components are estimated for the Canadian context. R&D needs are proposed for each technology area, which identifies critical areas where further research may make the difference in terms of commercial success. A final section is devoted to the strategic development and deployment of CCS infrastructure and systems.

Section Observations:

Specific R&D needs exist for each CCS component (capture, transport and storage), with the ultimate goal being technically and economically feasible CCS infrastructure and systems.

Current CO2 capture costs range from (CDN) $13 to 80/tCO2 captured; capture offers the greatest potential for cost reductions in the CCS system.

Transportation costs are (CDN) $6/tCO2 per 650 kilometres transported; transport technology is largely available today.

Geological storage costs range from (CDN) $3 to 9/tCO2; long-term storage is one of many promising ways to reduce GHG emissions from the portfolio of options available today.

The development of emissions hubs, a pipeline backbone and long-term storage will require upfront capital, but using this systems view will result in technologically and economically sound infrastructure development for the long term.

It is important to note that referring to any specific CCS technology as the ultimate solution, or silver bullet for a technology area, would be premature. At this early stage of CCS development, it is difficult to predict how the technological pathway might progress. However, a forward-looking description of potential pathways based on what is known today, and some generally accepted assumptions, can provide valuable insight into what the future might hold.
