It is unclear how much molecular hydrogen is available in natural reservoirs, but at least one company [15] specializes in drilling wells to extract hydrogen. Most hydrogen in the lithosphere is bonded to oxygen in water. Manufacturing elemental hydrogen requires the consumption of a hydrogen carrier such as a fossil fuel or water.

Hydrogen is a chemical element; it has symbol H and atomic number 1. It is the lightest element and, at standard conditions, is a gas of diatomic molecules with the formula H 2, sometimes called dihydrogen, [11] hydrogen gas, molecular hydrogen, or simply hydrogen. It is colorless, odorless, [12] non-toxic, and highly combustible.
US Geological Survey researchers say there could be 5.6 trillion metric tonnes of hydrogen in rocks and underground reservoirs
The concept of a society that uses hydrogen as the primary means of energy storage was theorized by geneticist J. B. S. Haldane in 1923. Anticipating the exhaustion of Britain's coal reserves for power generation, Haldane proposed a network of wind turbines to produce hydrogen and oxygen for long-term energy storage through electrolysis, to help address renewable power's variable output.

Hydrogen has long-been touted as a potential clean fuel as it only emits water vapour but it has failed to gain traction, mainly because of historically high production, transportation and storage ...
Hydrogen is set to an abundance of 12 on this scale. The Sun's photosphere consists mostly of hydrogen and helium; the helium abundance varies between about 10.3 and 10.5 depending on the phase of the solar cycle; [13] carbon is 8.47, neon is 8.29, oxygen is 7.69 [14] and iron is estimated at 7.62.

As of 2021, green hydrogen accounted for less than 0.04% of total hydrogen production. [5] Its cost relative to hydrogen derived from fossil fuels is the main reason green hydrogen is in less demand. [6] For example, hydrogen produced by electrolysis powered by solar power was about 25 times more expensive than that derived from hydrocarbons in ...
