Hydrogen (H₂) is a molecule that makes up 98% of the known universe, and it is the third most abundant element on the Earth’s surface. Hydrogen’s boiling point is -252.9°C, and its melting point is -259.1°C. It is the second coldest known fluid, next to helium. It is the lightest of all the gases; Earth’s gravity is not strong enough to hold it in its atmosphere. Therefore, when Hydrogen gas is released, it will rise up and eventually escape into space. Hydrogen is a component of Water, minerals, and acids. It makes up a fundamental part of all hydrocarbons and organic substances. Next to helium, it is the coldest known fluid. Hydrogen is valued for its reactive and protective properties.
Hydrogen is produced by:
Hydrogen and Oxygen are produced using the principle of Water electrolysis. Hydrogen and Oxygen, the two components of Water (H2O), are separated by passing a high electrical current through an electrolyte. Each gas purified in its own separate circuit is then pumped into the cylinders. We also use a process called Steam-Methane Reforming (SMR) to produce Hydrogen. This process, by the use of an external heat source, heats tubes in which a catalyst reaction takes place. The reaction separates natural gas into two components, Hydrogen and Carbon Monoxide.
