A geological model created by geologists from the U.S. Geological Survey suggests that Earth's subsurface may hold up to 5.6 × 10? million metric tons of natural hydrogen. The study published in Science Advances by Geoffrey Ellis and Sarah Gelman utilized this model to estimate the abundance of hydrogen in various parts of the Earth's subsurface.

Natural hydrogen is produced through chemical reactions within rocks and was previously thought to be scarce until the discovery of significant natural hydrogen reservoirs in locations like Albania and West Africa. The researchers' model indicates that there could be between 1 billion and 10 trillion tons of hydrogen in the subsurface, with an estimated average of 5.6 × 10? million metric tons. Harvesting even a small percentage of this hydrogen could potentially supply humanity's energy needs for up to two centuries.
