Flue Gas and CO2 Geosequestration in Surat and Bowen Basin Coals (2008-2011)

Geosequestration of CO2 is generally recognised as the major strategy for short term greenhouse gas emission mitigation. A major impediment is associated with the capture cost for extracting CO2 from power station flue gas. This project aims to develop the engineering and applied science basis for comparing injection of flue gas directly, rather than separated CO2 into coal seams, in association with methane recovery. This eliminates or reduces the need for CO2 capture plant, which is 80% of the total sequestration costs, or about $2.1 billion for a 1400MW power station, and could provide the lowest cost geosequestration opportunity.'',
