Are Vast Hydrogen Reserves Hidden Beneath Earth? – live Newztalkies.com
For years, scientists and companies have been searching for underground hydrogen reserves, driven by estimates that Earth contains trillions of tonnes of this clean, sustainable fuel. If harnessed, these geologic hydrogen reserves could revolutionize energy systems and help phase out fossil fuels. Despite some promising findings, the quest to locate these resources has faced significant challenges.
Potential Reserves to Power a Sustainable Future
Recent research reveals Earth might hold approximately 6.2 trillion tonnes of hydrogen trapped within rocks and reservoirs. This staggering amount is 26 times greater than the known global reserves of oil. Even if only 2% of this hydrogen—equivalent to 124 billion tonnes—were recoverable, it could fuel global energy needs and achieve net-zero carbon emissions for over 200 years.
The energy stored in these reserves could double that of the world’s known natural gas deposits, according to a study led by Geoffrey Ellis, a geochemist at the U.S. Geological Survey (USGS). These findings, recently published in Science Advances, highlight the untapped potential of natural hydrogen as a clean energy source.
How Natural Hydrogen Forms
Natural hydrogen forms underground through various chemical reactions in rocks, with one simple reaction splitting water into hydrogen and oxygen. Although earlier research suggested that hydrogen molecules are too small to remain trapped underground, discoveries in West Africa and Albania shifted this understanding. These findings confirmed that hydrogen can accumulate in reservoirs, possibly in significant quantities.
The research team developed a model to estimate hydrogen reserves, factoring in production rates, potential trapping mechanisms, and losses such as gas escaping to the atmosphere. The model predicted anywhere from 1 billion to 10 trillion tonnes of hydrogen, with 6.2 trillion tonnes being the most probable estimate.
Advantages of Natural Hydrogen
Unlike “green hy drogen,” produced through water electrolysis using renewable energy, or “blue hydrogen,” derived from fossil fuels, natural hydrogen is a readily available resource. Extracting it would eliminate the energy-intensive production process required by its synthetic counterparts. Furthermore, underground hydrogen reservoirs serve as natural storage systems, enabling efficient usage on demand.

“Natural hy drogen removes the storage problem associated with blue or green hydrogen. You could simply open a valve and access the fuel whenever needed,” Ellis explained to Live Science.
Challenges in Locating Reserves
Despite the immense potential, pinpointing accessible Natural hydrogen reserves remains a challenge. Most reserves may be buried too deep or located offshore, making extraction economically unfeasible. Researchers, including Ellis and his team, are working to identify geological conditions that favor hydrogen accumulation. Upcoming studies aim to shed light on potential reserves within the U.S.
The Role of Hydrogen in Future Energy Systems
Hy drogen is projected to account for up to 30% of global energy consumption in some sectors by 2050, with demand expected to increase fivefold. While current production methods focus on green and blue hydrogen, natural hydrogen could emerge as a game-changer due to its energy efficiency and reduced environmental impact.
