Natural hydrogen

Short description: Molecular hydrogen naturally occurring on Earth

Natural hydrogen (known as white hydrogen or gold hydrogen), is hydrogen that is formed by natural process[1][2] (as opposed to hydrogen produced in a laboratory or in industry). By contrast green hydrogen is produced from renewable energy sources, while grey, brown or black hydrogen are obtained from fossil fuels.[3] White hydrogen may be renewable. It is non-polluting and offers lower costs than industrial hydrogen.[4] Natural hydrogen has been identified in many source rocks in areas beyond the sedimentary basins where oil companies typically operate.[5][6]

## Origins

Sources of natural hydrogen include:[7]

* degassing of deep hydrogen from Earth's crust and mantle;[8]
* reaction of water with ultrabasic rocks (serpentinisation);
* water in contact with reducing agents in Earth's mantle;
* weathering \- water in contact with freshly exposed rock surfaces;
* decomposition of hydroxyl ions in the structure of minerals;
* natural water radiolysis;
* decomposition of organic matter;
* biological activity

## Reserves

Reserves have been identified in France.[9] In 2023 Pironon and de Donato announced the discovery of a deposit they estimated to be some 46 million to 260 million metric tons (several years worth of 2020s production).[10]

Prinzhofer and Derville demonstrated the existence of large reservoirs in a dozen countries, including Mali and the United States.[11] However, their potential remains unassessed.[12]

Emanations on the ocean floor have been identified but remain unexploited. A discovery in Russia in 2008 suggests the possibility of extracting native hydrogen in geological environments.

A large accumulation of natural hydrogen was discovered in a water well in Bourakebougou, Mali that was exploited to power the nearby village.[10]

### Mid-continent Rift System

Mid-continental Rift System

White hydrogen could be found or produced in the Mid-continental Rift System at scale. Water could be pumped down to hot iron-rich rock to produce hydrogen for extraction.[13]

## Geology

Natural hydrogen is generated from various sources. Many hydrogen emergences have been identified on mid-ocean ridges.[14] Serpentinisation occurs in the oceanic crust.

Diagenetic origin (iron oxidation) in the sedimentary basins of cratons, notably are found in Russia.

Mantle hydrogen and hydrogen from radiolysis (natural electrolysis) or from bacterial activity are under investigation. In France, the Alps and Pyrenees are suitable for exploitation.[15] New Caledonia has hyperalkaline sources that show dihydrogen emissions.[16]

Dihydrogen is soluble in fresh water, especially at depth (solubility increases with pressure).

## Literature

Vladimir Vernadsky originated the concept of natural hydrogen captured by the Earth in the process of formation from the post-nebula cloud. Cosmogonical aspects were anticipated by Fred Hoyle. From 1960-2010, V.N. Larin developed the Primordially Hydridic Earth concept[17][dubious - discuss] that described deep-seated natural hydrogen prominence[18] and migration paths.
