WebAny hydrogen that does enter the atmosphere quickly escapes the Earth’s gravity into outer space. Most hydrogen is produced by heating natural gas with steam to form syngas (a mixture of hydrogen and carbon monoxide). The syngas is separated to give hydrogen. Hydrogen can also be produced by the electrolysis of water. Web10 sep. 2024 · Researchers find 70 percent increase in atmospheric hydrogen over the past 150 years. Researchers insert a vacuum line down a borehole in Megadunes, Antarctica, to pump air out of the snow pack. WebHydrogen is a clean alternative to methane, also known as natural gas. It's the most abundant chemical element, estimated to contribute 75% of the mass of the universe. Here on earth, vast numbers of hydrogen atoms are contained in water, plants, animals and, of course, humans.
