Hydrogen gas is produced by several industrial methods. [ 1 ] Nearly all of the world's current supply of hydrogen is created from fossil fuels. [ 2 ][ 3 ]: 1 Most hydrogen is gray hydrogen made through steam methane reforming. In this process, hydrogen is produced from a chemical reaction between steam and methane, the main component of ...
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 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 H2, sometimes called dihydrogen, [ 11 ] but more commonly called hydrogen gas, molecular hydrogen or simply hydrogen. It is colorless, odorless, [ 12 ] non-toxic, and highly ...
1834 – Benoît Paul Émile Clapeyron – Ideal gas law. 1836 – John Frederic Daniell invents a primary cell in which hydrogen is eliminated in the generation of the electricity. 1839 – Christian Friedrich Schönbein publishes the principle of the fuel cell in the "Philosophical Magazine". 1839 – William Robert Grove develops the Grove cell.
Hydrogen can be produced from water by electrolysis.Electrolysis powered by renewable energy is carbon neutral.The Hydrogen Council said that, as of December 2023, manufacturers are preparing for a green hydrogen expansion by building out the electrolyzer pipeline by 35 percent to meet the needs of more than 1,400 announced projects.
Natural hydrogen. Natural hydrogen (known as white hydrogen, geologic hydrogen, [1] geogenic hydrogen, [2] or gold hydrogen), is hydrogen that is formed by natural processes [3][4] (as opposed to hydrogen produced in a laboratory or in industry). By contrast green hydrogen is produced from renewable energy sources, while grey, brown, blue or ...
Hydrogen pipeline transport is a transportation of hydrogen through a pipe as part of the hydrogen infrastructure. Hydrogen pipeline transport is used to connect the point of hydrogen production or delivery of hydrogen with the point of demand, pipeline transport costs are similar to CNG, [9] the technology is proven, [10] however most hydrogen is produced on the place of demand with every 50 ...
Water splitting is the chemical reaction in which water is broken down into oxygen and hydrogen: [1] Efficient and economical water splitting would be a technological breakthrough that could underpin a hydrogen economy. A version of water splitting occurs in photosynthesis, but hydrogen is not produced. The reverse of water splitting is the ...
