In the core of the subway chrome mine in Albania, a “massive source” of virtually pure natural hydrogen has been identified, with an annual emission of at least 200 tons of H2.
Findings in the Bulqizë mine
The Bulqizë mine, known to be an outstanding source of chromium essential for the production of stainless steel, was the site of this unprecedented discovery. Despite past incidents with explosions due to hydrogen leaks, only recently has the amount and purity of the “precious gas” been measured at the site.
They are located almost 1 km underground, and researchers have identified a small pool of hot water from which H2-rich gas constantly emanates. This place has received the name by the locality of “the Jacuzzi”, because this phenomenon resulted in the annual emission of 11 tons of hydrogen at 84% purity. However, additional studies suggest that the mine as a whole could release up to 200 tons per year of H2.
The potential of natural hydrogen
This finding stands out not only for the amount of hydrogen released, but also for its purity and ease of capture and measurement. With a flow rate a thousand times higher than geologically similar sites such as Oman, the Bulqizë mine sets a crucial precedent in natural hydrogen exploration.
Many researchers and experts see in this discovery a disruptive potential for global energy geopolitics, suggesting that natural hydrogen could be more common than anticipated and available in places where oil and gas are not currently extracted.
Present challenges and considerations
Although the total H2 reserve under the mine is estimated to be between 5,000 and 50,000 tons, “possibly insufficient” for large-scale commercial exploitation, the hydrogen could be used for on-site energy production. on-site. However, this enthusiasm is accompanied by a call for caution on the part of scientists, who stress the importance of considering the environmental impacts and sustainability of future exploration.
Could H2 be a renewable resource?
While some argue that natural hydrogen is not renewable due to its slow production rate compared to global energy needs, other studies suggest otherwise. These resources could be actively replenished, opening the door to a more sustainable energy future.
Exploration of natural hydrogen
This discovery not only redefines the understanding of natural energy resources, but also opens new avenues for the exploration and exploitation of natural hydrogen. As we move forward, balancing innovation with environmental responsibility is crucial, ensuring that the exploration of these resources contributes positively to the global energy landscape without compromising the delicate ecosystems involved.
