Natural hydrogen (known as white hydrogen, geologic hydrogen, [1] geogenic hydrogen, [2] or gold hydrogen) is molecular hydrogen present on Earth that is formed by natural processes [3] [4] (as opposed to hydrogen produced in a laboratory or in industry).
As of 2020, 5,648 hydrogen fuel cell buses are in use around the world, with 93.7% of them in China. Some early adopters of fuel cell buses have opted to focus on battery electric buses, with London having 950 battery electric buses, and 20 hydrogen fuel cell buses in their fleet as of 2023. [41]
Hydrogen technologies are applicable for many uses. Some hydrogen technologies are carbon neutral and could have a role in preventing climate change and a possible future hydrogen economy . Hydrogen is a chemical widely used in various applications including ammonia production, oil refining and energy. [ 1 ]
Hydrogen is also present naturally underground. This natural hydrogen, also called white hydrogen or gold hydrogen, can be extracted from wells in a similar manner as fossil fuels such as oil and natural gas. [129] [130] [11] White hydrogen could be found or produced in the Mid-continental Rift System at scale for a renewable hydrogen economy ...
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 can be produced from water by electrolysis.Electrolysis powered by renewable energy is carbon neutral.The business consortium 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.
