- White hydrogen, naturally occurring and renewed within the earth's surface, offers a renewable and potentially abundant source of clean energy for various applications.
- Recent discoveries of white hydrogen deposits in countries like France, Spain, and Canada have sparked interest in its extraction and utilization as a low-cost and environmentally friendly energy source.

Natural hydrogen(known aswhite hydrogen, geologic hydrogen[1]or gold hydrogen), is hydrogen that is formed by natural processes[2][3](as opposed to hydrogen produced in a laboratory or in industry). By contrastgreen hydrogenis produced fromrenewable energysources, while grey, brown, blue or black hydrogen are obtained fromfossil fuels.[4]White hydrogen may be renewable. It is non-polluting and offers lower costs thanindustrial hydrogen.[5]Natural hydrogen has been identified in many source rocks in areas beyond thesedimentary basinswhere oil companies typically operate.
Sources of natural hydrogen include:[8]
- degassing of deep hydrogen fromEarth's crustand mantle;[9]
- reaction of water withultrabasic rocks(serpentinisation);
- water in contact with reducing agents inEarth's mantle;
- weathering- water in contact with freshly exposed rock surfaces;
- decomposition ofhydroxyl ionsin the structure of minerals;
- natural waterradiolysis;
- decomposition of organic matter;
- biological activity

According to theFinancial Times, there are 5 trillion tons of natural hydrogen reserves worldwide.[10]A discovery in Russia in 2008 suggests the possibility of extracting native hydrogen in geological environments.[citation needed]Reserves have been identified in France,[11]Mali, the United States and approximately a dozen other countries.[12]
An accumulation of natural hydrogen was discovered in a water well in Bourakébougou, Mali, that was exploited to power the nearby village.[13]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).[13]In 2024, a natural deposit of helium and hydrogen was discovered in Rukwa, Tanzania.

Natural hydrogen is generated from various sources. Many hydrogen emergences have been identified onmid-ocean ridges.[16]Serpentinisation occurs in the oceanic crust.
Diagenetic origin (iron oxidation) in thesedimentary basinsofcratons, notably are found in Russia.
Mantle hydrogen and hydrogen fromradiolysis(naturalelectrolysis) or frombacterialactivity are under investigation. In France, theAlpsandPyreneesare suitable for exploitation.[17]New Caledonia has hyperalkaline sources that showhydrogenemissions.[18]
Hydrogen is soluble in fresh water, especially at moderate depths assolubilitygenerally increases with pressure. However, at greater depths and pressures, such as within the mantle,[19]the solubility decreases due to the highly assymetric nature of mixtures of hydrogen and water.
