Across Australia, groundwater is a vital resource that supports and strengthens communities, culture, the environment and numerous industries. Movement of groundwater is complicated, taking place horizontally, vertically and across different timescales from weeks to millions of years. It is affected by changes in climate, human use and geological complexities such as the type, geometry and distribution of rocks. Understanding how all these factors interact is known as a groundwater conceptual model and it is an important first step. This groundwater conceptualisation includes the Adavale Basin and the overlying Galilee Basin. Conceptualisation of the Galilee, Eromanga and Lake Eyre basins can be found in Hostetler et al. (2023). In the Adavale Basin this includes 1 aquifer in the Lake Eyre Basin, 5 aquifers in the Eromanga Basin, 3 aquifers in the Galilee Basin and 1 aquifer in the Adavale Basin (Wainman et al., 2023a, b). Confidence for each aquifer was calculated for both salinity and water levels (Gouramanis et al., 2023a, b, c, d). The confidence for each aquifer was added to show the overall confidence for the basin. The level of knowledge across all aquifers are moderate to low. The groundwater conceptualisations summarises the groundwater flow and potential connectivity between aquifers. Figures in this fact sheet show the distribution of the aquifers and aquitards, average salinity, potential aquifer yield and confidence over an area of 50 km along the cross section lines.

The potential for hydrogen production in the Adavale Basin region is assessed to provide a joint information base for hydrogen generation potential from renewable energy, groundwater, and natural gas coupled with carbon capture and storage (CCS). Hydrogen generation requires water, whether using electrolysis with renewable energy or steam methane reforming (SMR) with CCS. The data package includes the regional renewable energy capacity factor, aquifers and their properties (potential yield, salinity, and reserves or storativity), natural gas resources, and geological storage potential for carbon dioxide (CO2). This data guide gives examples of how the compiled data can be used. The renewable hydrogen potential is assessed based on renewable energy capacity factor and groundwater information (potential yield, salinity, and reserves or storativity). Eight aquifers from overlying basins (Galilee, Eromanga and Lake Eyre basins) are included in the assessment. The Adavale Basin region has low renewable hydrogen potential, except for some locations in the south-east and south-west. Although the renewable energy capacity factor in the basin is high, aquifers tend to have poor groundwater reserves or storativity, which results in lower overall renewable hydrogen potential. The Adavale Basin itself has no newly identified gas accumulation. However, gas reserves and contingent resources were identified in the overlying Galilee and Eromanga basins (Geoscience Australia, 2022). An assessment of CO2 geological storage also shows prospective storage areas in the Eromanga Basin within the Adavale Basin region (Bradshaw et al., 2023). Further work on identifying detailed gas potential is needed to assess hydrogen generation potential from gas.

Publicly available groundwater data have been compiled to provide a common information base to inform environmental, resource development and regulatory decisions in the Adavale Basin region. This data guide gives examples of how these data can be used. The data package included with this data guide captures existing knowledge of Adavale Basin aquifers and their properties, including salinity and water levels. The methods to derive these data for all Adavale Basin aquifers are outlined in the associated metadata files. These are described in groundwater conceptual models (Gouramanis et al., 2023). The Adavale Basin includes multiple aquifer systems that are grouped and more broadly defined as the Adavale Basin aquifers. Compiled data are assigned to these intervals and used to characterise groundwater systems at the basin scale. The data are compiled for a point in time to inform decisions on potential resource developments in the Basin. The available historical groundwater data can be used to assess the potential effects on groundwater. The data can also be used for other purposes, such as exploring unallocated groundwater resource potential. Data to January 2022 are used for this compilation.
