This web service shows the spatial locations of potential CO2 storage sites that are at an advanced stage of characterisation and/or development. The areas considered to be at an advanced stage are parts of the Cooper Basin in central Australia, a portion of the Surat Basin (Queensland), the offshore Gippsland Basin (Victoria), where the CarbonNet Project is currently at an advanced stage of development and the Petrel Sub-basin. This service will be presented in the AusH2 Portal.

Publicly available data was compiled to provide a common information base for resource development, and environmental and regulatory decisions in the Adavale Basin. This web service summarises the geological storage of carbon dioxide prospectivity of the Adavale Basin.

Publicly available data was compiled to provide a common information base for resource development, and environmental and regulatory decisions in the north Bowen Basin. This data guide gives examples of how these data can be used to create the components of a workflow to identify geological storage of carbon dioxide (CO2) opportunities. The data guide is designed to support the data package that provide insights on the geological storage of CO2 in the north Bowen Basin. The geological storage of CO2 assessment for the north Bowen Basin encompasses 3 of the 5 geological intervals, termed plays – these have been defined by Wainman et al. (2023). The assessment captures data from the Queensland Petroleum Exploration Database (QPED) from the Geological Survey of Queensland (GSQ) Open Data Portal (Queensland Government, 2022a); the Queensland Carbon Dioxide Geological Storage Atlas (Bradshaw et al., 2009), ZeroGen IGCC with CCS: A Case History (Garnett et al., 2014), OzSEEBASE (2021) and the Bowen and Surat Basins Regional Structural Framework Study (SRK Consulting, 2008) along with the scientific literature to inform the four components required for a potential geological storage of carbon dioxide system. These datasets were used to map out gross depositional environments and their geological properties relevant for geological storage of carbon dioxide. From these datasets, the following properties have been evaluated and mapped across the basin: injectivity, storage efficiency, containment and structural complexity. The data are compiled at a point in time to inform decisions on resource development opportunities. The data guide outlines the play-based workflow for assessing geological storage of CO2 prospectivity. Each of the elements required for a prospective geological storage of CO2 system are explained and mapped. These data were merged and spatially multiplied to show the relative assessment of geological storage of CO2 prospectivity across the basin, at both the play interval and basin scale. As an example of assessments contained within the data package, this data guide showcases the geological storage of CO2 prospectivity of the Rewan–Blackwater Play interval.

Carbon capture and storage (CCS) is a central component of many proposed pathways to reach net zero CO2 emissions by 2050. Even under conservative estimates, successful deployment of CCS projects at scale will require a substantial investment in the selection and development of new sequestration sites. While several studies have considered the potential costs associated with individual sequestration projects, and others have evaluated the costs of capture and sequestration in a generic manner, few have examined how regional differences in transport distances and reservoir properties may affect the overall costs of sequestration projects. In this abstract, we outline a new model to assess the costs associated with new carbon sequestration projects. The model evaluates the cost of CCS projects accounting for regional variations in transport distance and cost and well the storage properties of individual reservoirs. We present preliminary results from the modelling tool, highlighting potential opportunities for new CCS projects.

Publicly available data was compiled to provide a common information base for resource development, and environmental and regulatory decisions in the Cooper Basin. This data guide gives examples of how these data can be used to create the components of a workflow to identify geological storage of carbon dioxide (CO2) opportunities. The data guide is designed to support the data package that provide insights on the geological storage of CO2 in the Cooper Basin. The geological storage of CO2 assessment for the Cooper Basin encompasses 4 of the 6 geological intervals, termed plays – these intervals have been defined by Wainman et al. (2023). The assessment captures data from the Great Artesian Basin geological and hydrogeological surfaces update (Vizy and Rollet, 2022), Cooper Region Shale, tight and deep coal gas prospectivity of the Cooper Basin (Lech et al., 2020) (GBA), Cooper Basin architecture and lithofacies: Regional hydrocarbon prospectivity of the Cooper Basin (Hall et al., 2015) (CBAL), National Geoscience Mapping Accord Cooper and Eromanga Basins, Australia, seismic mapping data sets (NGMA, 2002), Queensland Petroleum Exploration Database (QPED) from the Geological Survey of Queensland (GSQ) Open Data Portal (2020a), and the Petroleum Exploration and Production System of South Australia (PEPS, 2021) along with the scientific literature to inform the 4 components required for a potential geological storage of CO2 system. These datasets are used to map out geological properties relevant for geological storage of CO2 assessments. From these datasets, the following properties have been evaluated and mapped across the basin: injectivity, storage efficiency, containment and structural complexity. The data are compiled at a point in time to inform decisions on resource development opportunities. The data guide outlines the play-based workflow for assessing geological storage of CO2 prospectivity. Each of the elements required for a working geological storage of CO2 system is explained and mapped. These data were then merged and spatially multiplied to show the relative assessment of geological storage of CO2 prospectivity across the basin, at both play interval and basin scale. As an example of assessments contained within the data package, this data guide showcases the geological storage of CO2 prospectivity the Toolachee Play interval.

Publicly available geological data in the north Bowen Basin region are compiled to produce statements of existing knowledge for natural hydrogen, hydrogen storage, coal and mineral occurrences. This data guide also contains assessment of the potential for carbon dioxide (CO2) geological storage and minerals in the basin region. Geochemical analyses of gas samples from petroleum, coal and coal seam gas boreholes in the basin show traces of natural hydrogen. However, the generation mechanism of the observed natural hydrogen concentration is unknown. Numerous mineral occurrences are found in the basin. Most contain gold, which historically has often been mined. Most occurrences are small, with some exceptions, such as Cracow, Golden Plateau, Kauffman’s Prospect and Miclere gold deposits. The north Bowen Basin has potential for epithermal gold-silver and gold-copper deposits in the deeper formations, but the depth of much of the basin makes exploration and mining difficult and expensive. There is also potential for sandstone-hosted uranium and paleoplacer gold deposits in the upper coal-bearing formations, such as what is seen in the Miclere area. The north Bowen Basin has a significant quantity of coal, with 152 deposits found in the basin, totalling about 47 billion tonnes of black coal. The results of CO2 geological storage assessment of 3 play intervals in the north Bowen Basin suggest there is low storage potential within the basin.
