Key facts
- Naturally occurring geologic hydrogen, or white hydrogen, is being explored as an alternative to green hydrogen.
- Recent research in Australia suggests hydrogen can be produced from magnetite in iron ore deposits under specific conditions.
- Canadian scientists have mapped natural hydrogen accumulation within the Canadian Shield.
- Companies like Max Power Mining and HyTerra are actively drilling and testing for white hydrogen in Canada and the U.S.
- The U.S. Geological Survey has identified prospective regions for geologic hydrogen resources within the United States.
The pursuit of naturally occurring geologic hydrogen, known as white hydrogen, is gaining traction across North America and Australia as a potential alternative to green hydrogen production. Scientists and startups believe this mined hydrogen could offer a more cost-effective and abundant energy source.
Recent research from Edith Cowan University in Australia suggests a method to stimulate hydrogen production from magnetite within iron ore deposits by exposing it to water under high pressure and temperature. Researchers believe this process, replicating conditions deep underground, could unlock significant resources, particularly in regions with large banded iron formations.
Concurrently, geochemists in Canada have identified steady accumulation of hydrogen gas within the ancient rocks of the Canadian Shield, indicating a potential for cost-effective domestic energy production. Local firm Max Power Mining is actively exploring these possibilities with drilling operations.
In the United States, exploration is underway with companies like HyTerra conducting production and well testing in Kansas and Nebraska. The U.S. Geological Survey has also mapped prospective areas for geologic hydrogen, highlighting regions across the Midwest, the Four Corners states, and coastal areas.
This surge in interest comes as enthusiasm for green hydrogen, produced via electrolysis, has waned due to high costs and challenges in scaling up projects. White hydrogen, if commercially viable, could represent a significant shift in the clean energy landscape.
