So next time someone asks, “What’s the future of clean energy?”—you just might say: it’s been right under our feet all along.
What Is Geologic Hydrogen?
Unlike the hydrogen that’s produced in factories using fossil fuels (called “gray hydrogen”) or electricity from renewables (called “green hydrogen”), geologic hydrogen is 100% natural. It forms underground when water reacts with certain types of rock—often at high temperatures and pressures. These chemical reactions produce hydrogen gas, which can then become trapped in porous rock, just like oil or natural gas.
It’s been known in theory for decades, but only recently have scientists begun to seriously map, measure, and model its abundance and accessibility. In places like Mali, this kind of hydrogen has been accidentally discovered—and even tapped into for electricity. That means this isn’t just theory—it’s already proven to work on a small scale.
What’s different now is that geoscientists are realizing the scale might be far larger than previously assumed. If early estimates are accurate, this could represent one of the largest natural energy deposits ever discovered—and it’s entirely renewable.
Why This Discovery Matters Big Time
It’s Clean
When hydrogen is used as a fuel (for example, in cars or to generate electricity), its only emission is pure water vapor. That means it could help reduce pollution, fight climate change, and support clean air initiatives around the globe.
It’s Plentiful
According to U.S. Geological Survey (USGS) estimates, there could be trillions of tons of hydrogen gas trapped below Earth’s surface. That’s enough to meet global energy needs for 100,000 to 200,000 years, depending on how much we can extract and how efficiently we use it.
It’s Already Being Used
Back in 1987, drillers in Bourakébougou, Mali, hit a well that released natural hydrogen. Instead of being dangerous, it turned out to be a stable, flammable gas—used to power an electric generator that’s still working today. That hydrogen well has provided reliable, low-cost electricity to the region for decades, with minimal maintenance.
It Changes the Energy Game
If we can reliably find and extract geologic hydrogen, it could reduce dependence on coal, oil, and even solar and wind (which have storage and intermittency issues). Unlike wind and solar, which fluctuate based on time of day and weather, geologic hydrogen offers consistent, baseload energy production, much like traditional power plants.
It Supports Energy Independence
Nations with geologic hydrogen deposits could drastically reduce their dependence on imported fossil fuels, improving energy security and boosting local economies. This discovery could reshape geopolitics as well as climate science.
The Science Behind It
Where Does It Come From?
There are three main ways geologic hydrogen is produced:
- Serpentinization – When water meets iron-rich rocks like olivine, a reaction happens that splits water into hydrogen and oxygen. This is one of the most common processes.
- Radiolysis – Natural radiation from uranium or thorium breaks down water molecules in rocks, releasing hydrogen.
- Microbial Activity – Some bacteria deep underground produce hydrogen as part of their metabolism. This adds a fascinating biological layer to the geochemistry.
These mechanisms happen over long time periods but can continually regenerate hydrogen, making this source potentially sustainable.
Where To Look For It
Researchers say the best spots to find natural hydrogen include:
- Ancient cratons (very old parts of Earth’s crust that haven’t moved much in billions of years)
- Areas with ultramafic rocks (high in iron and magnesium)
- Fault lines and geologic fractures (allowing trapped gases to accumulate)
- Deep sedimentary basins
More than 30 U.S. states might have potential hydrogen-rich zones, along with parts of Canada, Europe, Russia, Brazil, and Australia. Global interest is accelerating rapidly, as exploration companies and governments begin prospecting.
How They Found It
This discovery wasn’t just luck. Scientists combined multiple research tools and disciplines:
- Geologic mapping to identify rock types that can produce hydrogen
- Remote sensing and magnetotellurics to detect underground gas signatures and thermal gradients
- Direct drilling in known hydrogen-rich zones to sample and verify production
- Lab simulations to model long-term hydrogen production rates and geological stability
In short: they created a kind of geologic hydrogen recipe, allowing energy companies to search more strategically. Some even refer to it as “hydrogen prospecting 2.0.”
What’s Happening Now?
Exploration is currently active in multiple global hotspots:
- Mali, where the hydrogen well continues to power local infrastructure and has inspired broader African exploration
- Kansas, where startup HyTerra is drilling exploratory wells and running early-stage tests
- France, Spain, and Australia, all of which are mapping out hydrogen hotspots and conducting feasibility studies
- Russia and Brazil, which are conducting high-profile state-funded geological surveys
Even major oil and gas companies are taking notice. Some have announced initiatives to re-purpose existing drilling infrastructure to test for hydrogen pockets. Meanwhile, venture capital is flowing into hydrogen-focused startups, and governments are setting up subsidies, policy frameworks, and tax credits to support innovation.
What It Could Mean For the Future
This discovery could trigger massive change across:
Transportation
Hydrogen fuel-cell vehicles (like the Toyota Mirai or Hyundai Nexo) could finally go mainstream, powered by naturally sourced fuel. Hydrogen-powered trucks, buses, trains, and even airplanes are on the horizon.
Electricity
Instead of burning coal or natural gas, we could burn hydrogen—or run it through a fuel cell—for carbon-free electricity. In remote areas, mini hydrogen power stations could replace diesel generators.
Industry
Heavy industries like steel and cement, which are hard to electrify, could switch to clean hydrogen. These sectors account for roughly 20% of global emissions—so this would be a big win.
Jobs
Geoscientists, drilling engineers, environmental specialists, hydrogen logistics professionals, and data analysts could all see new career paths emerge. Entire new industries could be born around geologic hydrogen.
Equity
For developing countries with untapped underground resources, this could mean affordable access to clean, scalable energy. That could improve healthcare, education, and infrastructure for millions.

Challenges Ahead
Of course, there are hurdles:
- Locating reliable reserves is still a work in progress. Geological conditions vary widely.
- Extraction methods need to be optimized for cost, safety, and environmental impact.
- Storage and transport infrastructure (like pipelines and compression stations) must be built or retrofitted.
- Public understanding and trust are crucial. Safety concerns must be addressed through education and transparency.
- Regulations and international agreements will need to be developed to manage trade and environmental impact.
Still, the potential rewards far outweigh the risks, say experts. Most believe the timeline for mainstream integration is realistic—if there’s political will and private investment.
