CO₂ Capture

View publications on capture >>>

The objectives of the CCP Capture team are to:

Solve technical questions and confirm the economics of preferred technologies identified in Phase One
Pursue scale up of approximately 10 'preferred technologies' by at least one order of magnitude
Achieve 'ready for field demonstration' for at least one technology, with trials to start 2010-2011
Provide a comparative analysis of the performance and costs of different capture technologies

In the second phase of its work, the CCP focused on identifying technologies with the potential to significantly reduce the cost of capturing CO₂. It has already reviewed more than 200 capture technologies. The most promising of these, covering post-combustion, pre-combustion and oxyfiring were selected and developed from concept and are now being evaluated for potential demonstration. They are for use in oil and gas related scenarios – oil refineries, heavy oil extraction and natural gas fired power generation.

The CCP has two field trials scheduled for 2011:

Field demonstration of oxy-combustion at a Fluid Catalytic Cracking (FCC) refinery unit due to begin March 2011. Expected to capture up to 95% of FCC CO₂ emissions. Oxy-combustion could deliver a 45% cost advantage over pre-combustion in this scenario. View project factsheet
Pilot of oxy-fuel combustion on a once-through steam generator (OTSG) during 2011-12, expected to capture up to 99% of CO₂ emissions. Phase One work (2010) indicates that oxy-fuel combustion cost of capture will be in the range of $US125-150 per tonne, significantly less than post-combustion alternatives. View project factsheet
