About this choice question, Mr. Whittingham, you talked about the tar sands earlier. There seemed to be some technological questions about the purity of the CO2 coming out. There's also a cost question. I'm looking at some studies that say spillage happens from time to time as well--from the Alberta government itself, from C.D. Howe. I'm looking at downstreamtoday.com, a technology group that advises petrochemical, oil, gas companies—no left-wing radical, certainly.
They're estimating the cost somewhere between $225 and $250 per metric tonne. This was an independent report commissioned by the Government of Alberta. If you equate this out to what this means, it's about $22 per barrel of oil coming out of the tar sands. From everything we've heard from oil companies working in the patch, that would be a non-viable price of production. Why so much hope for the tar sands being able to use CCS cost-effectively? Under any pricing regime, $250 per tonne is very high, is it not?
