The most costly part of this whole system we're talking to you about today is the capture of the CO2. Transporting the CO2 is conventional pipeline technology, and it's well established. Areas in the United States, for example, have been using CO2 pipeline technology for decades to support enhanced oil recovery in their fields. It's really not seen as an impediment.
The challenge in Canada, particularly in western Canada, is that the CO2 sources are in a particular location and the places you'd want to use it for enhanced oil recovery or for deep sinks are in other locations. We need transportation infrastructure to connect up the sources and the uses of CO2, but that's in the area of capital investment, not in the area of technology, in terms of the challenges before us. Really, the transportation is not an issue for us.
