Project activity Hydrogen studies
Hydrogen studies aim to understand Australia’s underground hydrogen storage potential, estimate natural (geological) hydrogen resources and develop tools, such as the Hydrogen Economic Fairways Tool (HEFT), to aid decision-makers in the hydrogen sector.
This work is part of the Exploring for the Future Australia’s Future Energy Resources project.
Hydrogen can provide a pathway for deep decarbonisation of the Australian and global economy, when it is produced from renewable energy or uses other low carbon emission technologies. As a fuel, it produces no carbon emissions, only water. Hydrogen is especially important for the heavy vehicle transport and shipping industries, where electrification is not practical, as well as for replacing coal and natural gas in industries like steel-making and fertiliser production.
What are we doing?
Underground hydrogen storage
A major area of research is underground hydrogen storage, which is a safe and economical option for large-scale, commercial storage.
Salt caverns are already used for hydrogen storage in the UK and USA. Geoscience Australia is mapping rock salt accumulations across Australia, which can be used to create underground salt caverns for hydrogen storage. The feasibility of using depleted gas fields for hydrogen storage is also being investigated.
Caverns in thick salt accumulations are typically created by solution-mining. This process has been used to develop caverns for liquid-petroleum gas storage in Texas since the 1950s. It is estimated that there are over 100 salt caverns used worldwide for storage of energy resource commodities, with 4 currently used for hydrogen and more planned in Europe and the USA.
Natural hydrogen resources
The project also assesses Australia’s natural hydrogen resources. Natural hydrogen is found all over Australia (in natural gas, gold mines, some iron-rich rocks and more). Geoscience Australia has been collecting and analysing gas samples from different geological settings to better understand this new potential energy resource.
HEFT
The Hydrogen Economic Fairways Tool (HEFT) is an online decision support tool used to assess the economic feasibility of hydrogen projects in Australia.
Building on Geoscience Australia’s geospatial-economic expertise, HEFT helps identify prospective hydrogen production regions and zones, enabling decision-makers, planners and investors to identify the optimal regions to establish new hydrogen projects and production hubs.
Developed in collaboration with Monash University, HEFT includes a break-even analysis, underground hydrogen storage, liquid hydrogen, ammonia, and customisable operating and capital cost sliders for hydrogen production.

Australia’s Future Energy Resources
This project is evaluating the potential for new energy commodities hosted within sedimentary basins, including oil, natural gas and hydrogen, to support Australia’s transition to a low carbon economy. It will also assess the optimal locations for green and blue hydrogen production, including storage areas.
