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 H 2, sometimes called dihydrogen, [11] hydrogen gas, molecular hydrogen, or simply hydrogen. It is colorless, odorless, [12] non-toxic, and highly combustible.
Hydrogen is a chemical widely used in various applications including ammonia production, oil refining and energy. [1] The most common methods for producing hydrogen on an industrial scale are: Steam reforming, oil reforming, coal gasification, water electrolysis. [2] Hydrogen is not a primary energy source, because it is not naturally occurring ...
The current process of obtaining hydrogen can emit a lot of carbon dioxide into the atmosphere, but scientists have found a new — greener — way. How seawater can be used to generate valuable ...
Compressed hydrogen in hydrogen tanks at 350 bar (5,000 psi) and 700 bar (10,000 psi) is used for hydrogen tank systems in vehicles, based on type IV carbon-composite technology. [ 140 ] Hydrogen has a very low volumetric energy density at ambient conditions, compared with gasoline and other vehicle fuels. [ 141 ]
What is hydrogen water? As you probably already guessed, hydrogen water (or HW for short) is regular H2O that has been pumped with extra hydrogen. You can do this yourself at home with your own ...
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 ...
Due to its clean-burning characteristics, hydrogen is a clean fuel alternative for the automotive industry. Hydrogen-based fuel could significantly reduce the emissions of greenhouse gases such as CO 2, SO 2 and NO x. Three problems for the use of hydrogen fuel cells (HFC) are efficiency, size, and safe onboard storage of the gas. Other major ...
