Hydrogen is a chemical element, number 1 on the periodic table. It is a nonmetal, in a class by itself as the most basic, and most abundant, atomic element in the known universe. Its atomic structure consists of one proton and one electron. Hydrogen has two isotopes, a heavy hydrogen known as deuterium and tritium.

Because of its abundance, ease of manufacture, and high energy release per atom, hydrogen is frequently used as a fuel in many forms of power generation, including methanol production, petroleum refining and rocket propulsion. However, its volatility also makes it highly combustible. On Earth, this was discovered after several tragedies in the 20th century involving airships being destroyed when their hydrogen tanks (used for buoyancy) ignited and exploded.

In 2151 Commander Tucker referred to the risky job astronauts did with the use of rockets: In the old days, astronauts rode rockets with millions of litres of hydrogen burning under their seats. You think they said, gee I'd love to go to the moon today but it seems a little risky?. (ENT: "Silent Enemy")

In 2367, the Enterprise-D released large quantities of hydrogen from their Bussard collectors to escape from a Tyken's Rift. The hydrogen, when combined with a Calendenium-analog being released from an unknown alien vessel, created an explosion violent enough to rupture the rift, freeing both ships. The explosion released more energy than the combined firepower of Enterprise-D's phasers and photon torpedoes. (TNG: "Night Terrors")

The Lothra are an hydrogen-breathing species. (DS9: "Melora")

The H2 molecule has a "threshold" of 14.7 electron-volts. (VOY: "Relativity") This is respectably close to the ionization energy of hydrogen, which is 13.6 eV per atom.
