| Abstract: | Coal-fired power stations in Collie, Western Australia emit 10 million tonnes of CO2 per year. This study assesses the potential opportunities of geological storage of CO2 both within the Collie Basin and the onshore part of the adjacent Southern Perth Basin of Western Australia within 50 km of Collie town site through a desktop evaluation of existing data. The aquifers and coal formations within both basins have been evaluated for their suitability for storage based on geological, geographical and environmental criteria related to storage capacity, injectivity, proximity to sources of CO2, location of other natural resources and containment security. The study has concluded that there is limited scope for large-scale storage of CO2 within the Collie Basin. In addition the potential for storage within coals of either basin is not a viable solution. This assessment is based on published criteria for CO2 storage in sedimentary basins and coal-bearing formations. |
