A team of researchers at the GFZ Helmholtz Centre for Geosciences has pinpointed potential sources of naturally occurring hydrogen using advanced plate tectonic modeling. This discovery could contribute to a cleaner energy future by offering an alternative to fossil fuels.
The Need for Hydrogen Exploration
Hydrogen is a promising energy source due to its clean combustion process, which does not produce CO2 emissions. However, the challenge lies in large-scale production. Current synthetic methods require significant energy input, sometimes from fossil fuels, reducing their environmental benefits.
Scientists are now exploring natural hydrogen sources as a viable alternative. Until recently, the precise locations of large-scale natural hydrogen accumulations remained uncertain. Dr. Frank Zwaan and his team at GFZ have provided new insights into this issue.
Discovering Natural Hydrogen Hotspots
By utilizing tectonic modeling, the researchers found that mountain ranges containing deep mantle rocks near the surface could serve as potential hydrogen-rich environments. These regions create ideal conditions for large-scale hydrogen formation and accumulation, making them prime targets for extraction efforts.
Natural hydrogen can form through several geological processes, including the breakdown of organic materials and chemical reactions triggered by radioactive decay in the Earth's crust. However, the most promising mechanism involves the interaction between mantle rocks and water, known as serpentinization. This process alters rock composition, producing hydrogen gas as a byproduct.
For this reaction to occur efficiently, mantle rocks must be exposed to water under the right temperature conditions. This is most likely to happen in tectonically active regions where rock formations are brought closer to the surface.
Simulating Plate Tectonic Processes
The research team used advanced numerical simulations to analyze the full geological cycle, from the initial splitting of landmasses to the eventual formation of mountain ranges. Their models allowed them to determine where and when mantle rocks become exposed, as well as the conditions that enable hydrogen production.
Their findings indicate that mountain ranges provide significantly better conditions for natural hydrogen formation than rift basins. The relatively cooler temperatures in mountainous environments allow larger volumes of mantle rocks to remain within the optimal temperature range (200–350°C) for serpentinization. Additionally, water circulation along geological faults enhances the reaction, further increasing hydrogen output.
The study suggests that hydrogen production in mountain ranges could be up to 20 times greater than in other geological settings.
Expanding Exploration Efforts
These findings encourage intensified exploration efforts in mountainous regions such as the Pyrenees, European Alps, and Balkans, where preliminary evidence of hydrogen production has already been observed.
Dr. Zwaan emphasized the importance of developing targeted exploration methods, stating, "Identifying economic hydrogen reserves depends on understanding a region's geological history and how past tectonic activity has influenced resource formation."
He further added, "Timing is crucial. If we are to locate viable hydrogen deposits in mountain regions, we must analyze previous geological events, such as rifting periods that preceded mountain formation."
The Future of Hydrogen Energy
This research highlights the potential of natural hydrogen as a sustainable energy source. With improved exploration strategies and advanced modeling techniques, scientists can refine their search for hydrogen-rich locations, bringing the world closer to a clean energy future.
