Bluecap is an open-source python software library developed through a collaboration between Monash University and Geoscience Australia. The software enables geospatial economic simulation of Australian resource projects. The simulator's goal is to highlight regions of high potential value in the early planning/exploration phase. Bluecap is designed to assist companies in focusing their efforts on regions more likely to generate commercially-viable projects. It was initially developed for the purpose of supporting mineral exploration, and has recently been expanded to include the capability to model hydrogen production. The simulator is a pre-scoping tool that uses coarse-level empirical models to compare project prospects across large areas. Due to its broad scale, Bluecap lacks the detailed information necessary for full feasibility studies, and as such, it should not be used as the sole basis for investment decisions. The Bluecap software underpins Geoscience Australia's Hydrogen Economic Fairways Tool (HEFT) and Economic Fairways Mapper.

<div>Hydrogen is expected to be a key driver of the globe’s transition to net zero. &nbsp;</div><div>Australia is investing significantly, across government and business, as it pushes towards scalable and cost-effective hydrogen production. The Australian Government wants to develop and cultivate the domestic hydrogen industry to become a hydrogen superpower – exporting clean energy across the globe. With current expectations that the hydrogen industry could add an additional $50 billion to Australia’s GDP, the industry presents a great opportunity to support economic growth as Australia transitions to net zero (DCCEEW, 2022a). &nbsp;</div><div>However, much of hydrogen production remains unproven commercially at the necessary scale and there are still a lot of unknowns about how to effectively build this industry in Australia. &nbsp;</div><div>Geoscience Australia (GA), as Australia’s national geoscience agency, is undertaking precompetitive geoscience data and analysis to support the hydrogen sector. This includes conducting research and data analysis to lower the risk of exploration for natural hydrogen and salt caverns, the development of tools to support decision-making by hydrogen producers, and economic assessments into the feasibility of green steel production.&nbsp;</div><div>The economic benefits of precompetitive geoscience data and analysis for the hydrogen industry Deloitte Access Economics (DAE) was engaged to identify, quantify and, where possible, monetise the economic benefits of GA’s work across four case studies. &nbsp;</div><div>As hydrogen is a nascent sector, there is little to no current commercial activity. This limits the ability to estimate the full extent of the economic benefits of GA’s work. As the hydrogen industry matures over the next five years, we expect more economic benefits will be realised, particularly as tenement uptake translates into hydrogen production. &nbsp;</div><div>Through analysis of four current case studies, it is evident that GA’s work is providing clarity and confidence to support large-scale investment decisions. Overall, GA’s work has the potential to deliver Australia an important competitive advantage and fast-track development of the local hydrogen industry. &nbsp;</div><div>Hydrogen Economic Fairways Tool (HEFT): found to enable timely and informed decision-making and lower the risk of investing in, and entering, the hydrogen industry. Specifically, the tool provides significant efficiencies for hydrogen companies, saving $30,000 to $50,000 per prospective project in time and reduced due diligence costs. &nbsp;</div><div>GA research on natural hydrogen: expected to have stimulated tenement uptake activity in South Australia, to explore for natural hydrogen. If even just one tenement was taken up as a result of GA’s data, it could be associated with economic benefits of around $22 million to the hydrogen industry, over a ten-year period (2022-23 to 2031-32). &nbsp;</div><div>GA research on salt cavern storage: hydrogen storage can be prohibitively expensive, which can stall the development of hydrogen projects. GA’s research highlighted salt caverns as a cheaper alternative. If just one industry player switched from conventional gas storage to salt caverns, salt cavern storage could lower the cost by $208 million, over ten years. In addition, salt cavern storage could avoid the loss of $4.1 million worth of hydrogen over the same period (2022-23 to 2031-32). &nbsp;</div><div>The techno-economic assessment of green steel production: GA’s research identified cost-effective locations for green steel production, which could be competitive with conventional steel at a carbon price of $148 per tonne of carbon dioxide&nbsp;</div><div><br></div><div><br></div>

All commercially produced hydrogen worldwide is presently stored in salt caverns. The only known thick salt accumulations in eastern Australia are found in the Boree Salt of the Adavale Basin in central Queensland. The Boree Salt consists predominantly of halite and is considered to be suitable for hydrogen storage. In 2021, Geoscience Australia contracted Intrepid Geophysics to perform 3D geological modelling of the Adavale Basin, particularly interested in modelling the Boree Salt deposit in the region. The developed 3D model has identified three main salt bodies of substantial thicknesses (up to 555 m) that may be suitable for salt cavern construction and hydrogen storage. These are the only known salt bodies in eastern Australia and represent potentially strategic assets for underground hydrogen storage. However, there are still unknowns with further work and data acquisition required to fully assess the suitability of these salt bodies for hydrogen storage. Geoscience Australia has transformed Intrepid Geophysics' Adavale Basin 3D Modelling dataset into Petrel. This Petrel dataset is part of Geoscience Australia's Exploring for the Future program.

Natural hydrogen is receiving increasing interest as a potential low-carbon fuel. There are various mechanisms for natural hydrogen generation but the reduction of water during oxidation of iron in minerals is recognised to be the major source of naturally generated H2. While the overall reaction is well known, the identity and nature of the key rate limiting steps is less understood. This study investigates the dominant reaction pathways through the use of kinetic modelling. The modelling results suggest there are a number of conditions required for effective H2 production from iron minerals. These include the presence of ultramafic minerals that are particularly high in Fe rather than Mg content, pH in the range of 8 to 10, solution temperatures in the 200 to 300oC range, and strongly reducing conditions. High reaction surface area is key and this could be achieved by the presence of finely deposited material and/or assemblages of high porosity or with mineral assemblages with surface sites that are accessible to water. Finally, conditions favouring the co-deposition of Ni together with FeO/Fe(OH)2-containing minerals such as brucite (and, possibly, magnetite) could enhance H2 generation
