Hydrogen is the most prevalent naturally occurring element in the universe. It is found in many different forms, however the gas is the most profitable and usable form. Beneath the surface of planets, deep within the crust, Hydrogen gas is found within sealed pockets of the planet’s crust. Gas extractors are able to drill into the surface, searching for underground pockets of gas or other sources of Hydrogen Gas.
For example, the standardized method of extracting Hydrogen Gas from an Oceanic Planet is to use an age old process of electrolysis. This process is slow, but essentially involves super heating vast quantities of water and separating the Hydrogen Gas from the Oxygen Gas once the water has evaporated. Either method produces results, or in some cases a combination of both is used to facilitate a more steady income of the precious gas.
