Australia’s red soil may be hiding a massive clean energy source

Researchers at Edith Cowan University (ECU) have identified a potentially important source of low-emission energy beneath Western Australia, where vast iron-rich formations may be capable of generating naturally occurring hydrogen.

The findings suggest that the region's geology could eventually support a new domestic energy source and, if developed at scale, a major hydrogen export industry.

Magnetite Could Generate Hydrogen Underground

The research focuses on magnetite, a mineral that is abundant in Western Australia's huge iron ore deposits across the Pilbara region.

Scientists from ECU's School of Engineering found that magnetite can release hydrogen gas when it reacts with hot water under conditions similar to those deep below the Earth's surface.

The team also discovered a way to stimulate the process. By injecting a solution into banded iron formations, the researchers were able to increase hydrogen generation, raising the possibility that naturally produced hydrogen could one day be deliberately enhanced underground.
