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 ...
More than $150 billion worth of green hydrogen projects have been announced globally in the past nine months. China, Japan and South Korea recently joined a slew of European countries setting net ...
1965 – The first commercial use of a fuel cell in Project Gemini. 1965 – Allis-Chalmers builds the first fuel cell golf carts. 1966 – General Motors presents Electrovan, the world's first fuel cell automobile. [20] 1966 – Slush hydrogen. 1966 – J-2 (rocket engine) liquid hydrogen rocket engine flies..
Illustrating inputs and outputs of steam reforming of natural gas, a process to produce hydrogen and CO 2 greenhouse gas that may be captured with CCS. Steam reforming or steam methane reforming (SMR) is a method for producing syngas (hydrogen and carbon monoxide) by reaction of hydrocarbons with water.
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 ...
