Researchers in the United States, Canada, and Australia are intensifying efforts to map and develop sources of geologic hydrogen, a naturally occurring resource found in underground rocks. This initiative represents a potential shift in hydrogen energy strategy, as interest in green hydrogen production has moderated due to high costs and difficulties in securing long-term supply agreements.
A significant development emerged in Australia, where scientists at Edith Cowan University published research on hydrogen generation from magnetite, a mineral present in Western Australia’s iron ore deposits in the Pilbara region. The study involved exposing magnetite samples to water at elevated temperatures and pressure for extended periods, simulating deep subsurface conditions. The researchers identified methods to stimulate hydrogen production by injecting solutions into banded iron formations, offering insights into natural hydrogen formation processes. According to the research team, Western Australia’s extensive banded iron formations could provide substantial quantities of this resource if extraction methods can be scaled effectively.
Canadian researchers from the University of Toronto and University of Ottawa have made parallel discoveries, documenting steady accumulation of hydrogen gas in the Canadian Shield, among Earth’s oldest rock formations. These findings suggest significant untapped potential for domestic hydrogen sources, with Canada’s geological conditions particularly favorable for natural hydrogen generation through underground chemical reactions between rocks and groundwater. Exploration efforts are already underway, with Canadian firm Max Power Mining conducting drilling operations at the Lawson Complex in Saskatchewan.
In the United States, commercial exploration activities are progressing, including production testing by HyTerra at projects in Kansas and Nebraska. The U.S. Geological Survey previously released a prospective resource map identifying regions with potential geologic hydrogen accumulations, spanning the mid-continent, Four Corners states, the California coast, and Eastern seaboard areas. These concurrent developments across multiple countries indicate growing confidence that geologic hydrogen could provide a cost-effective energy alternative to current hydrogen production methods.
