Researchers Identify Potential for Green Hydrogen Production in Australian Iron Ore

Iron Ore as a Hydrogen Source

Researchers from Edith Cowan University have identified a potential method to generate green hydrogen using the vast iron ore deposits found in Western Australia. The findings suggest that the region's red soil, known for its significant mineral wealth, may hide a vast clean energy source that could contribute to low-emission power production.

Green hydrogen is produced through processes that avoid the emission of greenhouse gases, unlike traditional hydrogen production which typically relies on fossil fuels. The use of iron ore deposits as a catalyst or medium for this production represents a shift in how the region's natural resources could be utilized for the energy transition.

Australia's Broader Energy Landscape

This research coincides with a broader acceleration in Australia's transition from coal to renewable energy. The country has seen record investment in wind, solar, and battery storage technologies as part of this shift. Additionally, electrification is being pursued as a means to provide energy security by leveraging the renewable resources abundant across the continent.

Beyond wind and solar, Australia possesses other significant mineral resources that may play a role in future energy security. According to government data, Australia holds a major share of the world's thorium resources, with approximately 1,391 kt of identified in situ thorium resources as of 2024. While thorium is not currently used as an energy resource, the government notes it could serve as a nuclear energy source in the future. Most of these thorium resources are associated with heavy mineral sand deposits.

Technological Integration

Experts at the Australian Clean Energy Summit have highlighted that electrification offers an opportunity because it is already technically possible to deploy. This transition involves replacing technologies that burn fossil fuels with electric alternatives that are cleaner and increasingly cheaper to operate.

Specific technologies mentioned in the context of this transition include thermal batteries, which are described as especially promising for increasing efficiency. These advancements in electrification and storage are viewed as complementary to the discovery of new low-emission fuel sources, such as the green hydrogen potential found in iron ore.

Future Clean Energy Development

Australia continues to develop various clean energy technologies to meet its emission reduction targets. These efforts include the advancement of renewable energy, carbon capture and storage (CCS), and low-emissions hydrogeology. The potential to tap into underground hydrogen sources is also a point of scientific interest, with some researchers exploring "recipes" to find and extract clean hydrogen from the earth.
