The Global Race to Unlock Geologic Hydrogen: A New Frontier in Clean Energy

The discovery of vast reserves of naturally occurring hydrogen beneath the Earth’s surface is reshaping the global energy landscape.

With growing investments and collaborations among governments, private companies, and research institutions, this hidden resource could pave the way for a carbon-free energy future.

The pursuit of geologic hydrogen, a naturally forming source of clean energy, has sparked innovation and excitement worldwide.

Groundbreaking research into geologic hydrogen could transform it into a competitive, clean alternative to fossil fuels, with significant funding aimed at optimizing its extraction and production.

Understanding Geologic Hydrogen and Its Promise

Hydrogen, the universe’s most abundant element, is generally bound with other elements like oxygen in water.

However, recent discoveries have revealed underground pockets of pure hydrogen, known as geologic hydrogen, which could provide an economical, scalable source of clean energy.

This year, the U.S. Department of Energy (DOE) allocated $20 million in research grants to 18 teams to explore methods of extracting and utilizing geologic hydrogen efficiently.

Among the recipients is MIT Assistant Professor Iwnetim Abate, whose team received $1.3 million to study optimal conditions for producing hydrogen underground.

“We aim to optimize the reaction parameters to make the reaction faster and produce hydrogen in an economically feasible manner,” Abate said. His team is focused on designing materials and technologies that could accelerate this process.

The key lies in natural chemical reactions. When water interacts with iron-rich rocks deep underground, the iron oxidizes, producing hydrogen gas.

Abate’s work will explore how to stimulate and control these reactions for large-scale applications.

A Growing Global Interest

Governments around the world are racing to tap into geologic hydrogen’s potential.

For instance, France has pledged funding to explore this resource, while U.S. lawmakers are holding discussions to encourage hydrogen extraction initiatives.

The industry’s growth is supported by startups like Natural Hydrogen Energy and Koloma, which are securing funding from entities such as Amazon and Bill Gates.The stakes are high. Current commercial hydrogen costs about $2 per kilogram when derived from fossil fuels, while “green hydrogen,” produced using renewable energy, costs around $7 per kilogram.

However, geologic hydrogen has the potential to drop prices to just $1 per kilogram.

Douglas Wicks, program director at the DOE’s Advanced Research Projects Agency–Energy (ARPA-E), notes, “If you get hydrogen at a dollar a kilo, it’s competitive with natural gas on an energy-price basis.”

Challenges and Collaborative Solutions

Despite the promise, geologic hydrogen comes with uncertainties.

Researchers need to understand how to stimulate these natural reactions, engineer safe extraction methods, and assess the feasibility of scaling production.

As Wicks explained, the field is “a total white space.”

To address these questions, researchers are employing diverse approaches.

Teams at institutions like the Colorado School of Mines, Texas Tech University, and Los Alamos National Laboratory are experimenting with technologies from the oil and gas sector to extract hydrogen safely and efficiently.

Others are leveraging advanced modeling tools to simulate how hydrogen forms in rocks.

Entrepreneurs like Viacheslav Zgonnik, CEO of Denver-based startup Natural Hydrogen Energy, are also exploring ways to accelerate hydrogen production.

“The idea is to find ways we can accelerate that reaction and control it so we can produce hydrogen on demand in specific places,” Zgonnik said.

Innovation Rooted in Personal Motivation

For Iwnetim Abate, this mission is personal. Growing up in Ethiopia, frequent power outages meant relying on kerosene lamps for light and wood or charcoal for cooking.

“That was my story all the way until the end of high school and before I came to the U.S. for college,” Abate shared. Now, his research could help bring sustainable energy to communities like the one he grew up in.

Abate is not the only one inspired by personal connections to this energy solution.

Malian entrepreneur Aliou Diallo transformed his country’s unexpected hydrogen discovery into an energy enterprise.

His company, Hydroma, has become the world’s first hydrogen exploration firm, demonstrating that even energy-poor regions can become leaders in the global clean energy revolution.

Experimentation and Scaling Up

Abate’s research is taking a two-pronged approach. First, his team is designing a catalyst fluid to trigger and accelerate the hydrogen-producing reactions in rocks. “A catalyst that’s inexpensive and abundant will allow us to enhance the production rate and make the process economically feasible,” explained Yifan Gao, a postdoctoral researcher in Abate’s lab.

Second, they are developing a high-throughput system powered by artificial intelligence (AI) and robotics. This system will test different catalyst combinations under various conditions to optimize hydrogen production. The AI will also predict the best materials and methods for specific geological compositions.

Looking ahead, the team plans to design a reactor that will allow them to replicate these reactions in real-world environments. “The lab-scale device will inform the design of a plant-scale reactor that can be implanted into the subsurface,” Abate said.

A Collaborative Effort

This research draws on expertise from multiple disciplines. At MIT, Yang Shao-Horn is contributing computational analysis, while Cornell University’s Esteban Gazel is analyzing the geological formations that produce geologic hydrogen. These collaborations aim to create a comprehensive understanding of how to harness this energy resource.

For Wicks, the potential of geologic hydrogen is transformative. “If we can understand how to stimulate these rocks into generating hydrogen, safely getting it up, it really unleashes the potential energy source,” he said. Drawing on established oil and gas expertise, the field could achieve rapid advancements in extraction and distribution methods.

The Road Ahead

As researchers and industry leaders push the boundaries of geologic hydrogen, this emerging field represents a critical step toward reducing global dependence on fossil fuels. The potential to scale production, drive costs down, and provide sustainable energy is unparalleled. For Abate, the journey is not only about advancing technology but also about fulfilling a vision of equitable energy access.

“The problem is global; the solution is global,” he said. “But the connection with my personal journey makes me personally connected to the problem and to the solution.” With collaborative innovation, the dream of limitless, clean hydrogen energy may soon become reality.
