A recent study suggests that substantial reserves of white hydrogen could be present in mountain ranges, sparking optimism that this eco-friendly gas could be extracted to bolster efforts in combating the climate crisis. White hydrogen, known for its potential to replace environmentally harmful fossil fuels, has garnered attention in recent years as a promising fuel source. Scientists have been investigating the existence of this potent fuel, also referred to as “natural” or “geologic” hydrogen, in significant quantities beneath the Earth’s crust for the past couple of decades.
Through extensive research, geologists have been studying the formation and potential locations of white hydrogen. The challenge has been identifying areas with abundant reserves that could meet the world’s growing energy demands. To address this issue, a team of researchers utilized computer models to analyze the movement of tectonic plates and identify regions where ideal conditions for producing white hydrogen exist. Their findings point to mountain ranges such as the Pyrenees and the European Alps as potential hotspots, as detailed in a study published in the journal Science Advances.
Hydrogen, which leaves behind only water when burned, has long been considered a green energy solution, particularly for energy-intensive industries like aviation and steel production. However, the majority of commercially available hydrogen is currently produced using fossil fuels, negating its environmental benefits. This is where the promise of white hydrogen comes into play.
The intrigue surrounding white hydrogen traces back to a serendipitous discovery in Mali in 1987 when an explosion at a water well revealed its presence. Since then, white hydrogen deposits have been identified in various countries, including the US, Australia, and France, but the challenge has been locating substantial quantities. Geologist Frank Zwaan from the Helmholtz Centre for Geosciences in Germany noted that while hydrogen is naturally produced in nature, it has not been extensively explored as an energy source. With the urgent need for sustainable alternatives amid the escalating climate crisis, the quest for viable energy options has intensified.
White hydrogen forms through a process called serpentization, where water interacts with iron-rich rocks from the Earth’s mantle to generate hydrogen. Although these rocks are typically found deep within the Earth’s crust where water is scarce, geological forces over millions of years can bring them closer to the surface. By utilizing tectonic plate modeling, scientists have identified mountain ranges with ideal conditions for the accumulation of white hydrogen due to the presence of significant mantle rock deposits at suitable temperatures and accessible water sources.
The potential for vast quantities of white hydrogen in mountain ranges like the Pyrenees and the European Alps suggests that this discovery could revolutionize the energy landscape, offering a renewable alternative to traditional fossil fuels. Geochemist Geoffrey Ellis from the US Geological Survey commented on the significance of this research, emphasizing the transformative potential of white hydrogen as a game-changing energy source.
A person not involved in the research mentioned that the processes responsible for bringing mantle rocks near the Earth’s surface are already well-documented. The uniqueness of this study, as communicated to CNN, lies in its provision of a quantitative approach to evaluating the potential for white hydrogen in different settings where mantle rocks have been uplifted. The significant challenge ahead will be pinpointing where white hydrogen accumulates in substantial reservoirs that can be drilled into, according to Zwaan. He also suggested the possibility of inducing serpentization artificially by drilling into areas where mantle rocks are in close proximity to the surface and injecting water.
Preliminary exploration efforts are underway in various regions such as France, the Balkans, and the United States. This new research is poised to direct geologists towards areas with the highest prospects for large-scale white hydrogen resources and is expected to greatly impact geological hydrogen exploration, as stated by Ellis.
Establishing a viable white hydrogen industry involves several stages, including devising cost-effective methods for extraction and developing infrastructure for its storage and transportation. Zwaan predicts that commercialization could take several decades and cautions against expecting instant results, likening the process to the gradual evolution of the oil industry. Despite the gradual nature of progress, Zwaan remains optimistic, drawing parallels between the historical trajectory of oil utilization and the potential future of white hydrogen.
