Researchers at Edith Cowan University in Australia discovered a potential green hydrogen goldmine beneath Western Australia’s iron ore deposits, identifying a natural geological process where water reacts with underground magnetite to generate clean energy. According to a study published in the International Journal of Hydrogen Energy, this subterranean reaction could provide a vast, untapped energy reserve and position the region as a major exporter of clean fuel.
Magnetite Reactions Unlock Natural Hydrogen Potential
The search for natural hydrogen sources has accelerated as industries look for alternatives to fossil-fuel-derived energy. Natural hydrogen generation occurs through specific geological processes, including when hot water contacts the magnetite mineral found abundantly within iron ore. A research team led by scientists at Edith Cowan University investigated how much hydrogen gas already exists within Western Australia’s iron ore formations and how much these deposits might produce over time, as reported by ScienceAlert. To replicate underground conditions, the laboratory experiments subjected magnetite to high pressures and temperatures of 200 °C (392 °F) for 60 days. The tests revealed that water and magnetite combinations successfully produced hydrogen gas. Furthermore, the experiments established that magnetite powder generated approximately five times more hydrogen per gram than solid magnetite slabs. Fluid access to the mineral through fractures, pores, and permeable rock proved essential for driving the chemical reaction.

Geological Factors and Future Energy Exports
According to Edith Cowan University chemical engineer Alireza Keshavarz, the underground reserves contain enough hydrogen to benefit Australia for generations and potentially establish the country as a major clean energy exporter. The laboratory findings indicate that hydrogen yields depend directly on mineral surface accessibility. When water contacts fresh mineral surfaces via permeable pathways, production rates increase significantly compared to solid rock slabs. Energy engineer Stefan Iglauer from Edith Cowan University noted that the work bridges the gap between controlled laboratory settings and real-world geological systems. The experiments also revealed that the hydrogen-producing reaction transforms much of the remaining magnetite into hematite. At larger scales, this transformation might create a natural protective layer that restricts water from reaching fresh magnetite surfaces. Understanding these mineral alterations improves the accuracy of future geological modeling and aids in assessing rock integrity for potential gas geo-storage applications.
