This web service features Australian hydrogen projects that are actively in the investigation, construction, or operating phase, and that align with green hydrogen production methods as outlined in Australia's National Hydrogen Strategy. The purpose of this dataset is to provide a detailed snapshot of hydrogen activity across Australia, and includes location data, operator/organisation details, and descriptions for all hydrogen projects listed.

The discovery of strategically located salt structures, which meet the requirements for geological storage of hydrogen, is crucial to meeting Australia’s ambitions to become a major hydrogen producer, user and exporter. The use of the AusAEM airborne electromagnetic (AEM) survey’s conductivity sections, integrated with multidisciplinary geoscientific datasets, provides an excellent tool for investigating the near-surface effects of salt-related structures, and contributes to assessment of their potential for underground geological hydrogen storage. Currently known salt in the Canning Basin includes the Mallowa and Minjoo salt units. The Mallowa Salt is 600-800 m thick over an area of 150 × 200 km, where it lies within the depth range prospective for hydrogen storage (500-1800 m below surface), whereas the underlying Minjoo Salt is generally less than 100 m thick within its much smaller prospective depth zone. The modelled AEM sections penetrate to ~500 m from the surface, however, the salt rarely reaches this level. We therefore investigate the shallow stratigraphy of the AEM sections for evidence of the presence of underlying salt or for the influence of salt movement evident by disruption of near-surface electrically conductive horizons. These horizons occur in several stratigraphic units, mainly of Carboniferous to Cretaceous age. Only a few examples of localised folding/faulting have been noted in the shallow conductive stratigraphy that have potentially formed above isolated salt domes. Distinct zones of disruption within the shallow conductive stratigraphy generally occur along the margins of the present-day salt depocentre, resulting from dissolution and movement of salt during several stages. This study demonstrates the potential AEM has to assist in mapping salt-related structures, with implications for geological storage of hydrogen. In addition, this study produces a regional near-surface multilayered chronostratigraphic interpretation, which contributes to constructing a 3D national geological architecture, in support of environmental management, hazard mapping and resource exploration. <b>Citation: </b>Connors K.

Hydrogen can be used for a variety of domestic and industrial purposes such as heating and cooking (as a replacement for natural gas), transportation (replacing petrol and diesel), and energy storage (by converting intermittent renewable energy into hydrogen). The key benefit of using hydrogen is that it is a clean fuel that emits only water vapour and heat when combusted. To support implementation of the National Hydrogen Strategy, Geoscience Australia in collaboration with Monash University are releasing the Hydrogen Economic Fairways Tool (HEFT). HEFT is a free online tool designed to support decision making by policymakers and investors on the location of new infrastructure and development of hydrogen hubs in Australia. It considers both hydrogen produced from renewable energy and from fossil fuels with carbon capture and storage. Tune in to this seminar to discover HEFT’s capabilities, its potential to attract worldwide investment into Australia’s hydrogen industry, and what’s up next for hydrogen at Geoscience Australia.

There is significant momentum in Australia to develop a hydrogen production industry. The Australian economy is highly reliant on fossil fuel exports and hydrogen is seen as a pathway to decarbonise Australia’s economy and as a source of ongoing export revenue in future years. Although not readily available in its natural form, hydrogen can be produced as a gas and used for a variety of everyday tasks and industrial uses: heating and cooking, transportation, alternative feedstock in industry, and energy storage. This talk provides a 101 on hydrogen and maps out a vision of hydrogen production in Australia.

The potential for hydrogen production in the Cooper 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) of gas with CCS. The data package includes the regional renewable energy capacity factor, aquifers and their properties (potential yield, salinity, and reserves or storativity), and geological storage potential of 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). Three aquifers from overlying basins (Eromanga and Lake Eyre basins) are included in the assessment. The Cooper Basin region has high renewable hydrogen potential. The presence of good aquifer throughout the basin combined with high renewable energy capacity factor resulted in significant areas with high hydrogen potential. The Cooper Basin has significant hydrocarbon resources, primarily for gas (Geoscience Australia, 2022). Although most known hydrocarbon resources have depleted since production began in the 1960s (Smith et al., 2015), a large amount of gas remains, including conventional gas (1,058 PJ reserves and 1,598 PJ resources) and unconventional basin-centred gas (2,265 PJ resources). An assessment in the overlying Eromanga Basin suggests that most areas over the Cooper Basin are prospective for potential CO2 geological storage (Bradshaw et al., 2023). Further work on identifying detailed gas potential is needed to assess hydrogen generation potential from SMR coupled with CCS.
