Hydrogen gas is very rare in Earth's atmosphere (around 0.53 ppm on a molar basis [103]) because of its light weight, which enables it to escape the atmosphere more rapidly than heavier gases. However, hydrogen, usually in the form of water, is the third most abundant element on the Earth's surface, [ 104 ] mostly in the form of chemical ...
1809 – Gay-Lussac's law, a gas law relating temperature and pressure. 1811 – Avogadro's law, a gas law relating volume and amount of substance. 1819 – Edward Daniel Clarke invents the hydrogen gas blowpipe. 1820 – W. Cecil writes a letter, "On the application of hydrogen gas to produce a moving power in machinery". [6] [7]

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 natural gas.

Hydrogen, being the lightest existing gas (7% the density of air, 0.08988 g/L at STP), seems to be the most appropriate gas for lifting.It can be easily produced in large quantities, for example with the water-gas shift reaction or electrolysis, but hydrogen has several disadvantages:

Henry Cavendish FRS (/ ˈ k æ v ən d ɪ ʃ / KAV-ən-dish; 10 October 1731 – 24 February 1810) was an English experimental and theoretical chemist and physicist.He is noted for his discovery of hydrogen, which he termed "inflammable air". [1]
