Bookmark or Share- Hydrogen - Department of EnergyHydrogen is a highly versatile energy carrier and an input to several important chemical and industrial processes. When it is produced cleanly—from renewables, nuclear power, or fossil energy with carbon capture—it can play a vital role in reducing emissions from some of the hardest-to-decarbonize parts of our economy. These parts of our economy are also among our most energy-intensive and ...
- Hydrogen | Properties, Uses, & Facts | BritannicaHydrogen, a colorless, odorless, tasteless, flammable gaseous substance that is the simplest member of the family of chemical elements. The earliest known chemical property of hydrogen is that it burns with oxygen to form water; indeed, the name hydrogen is derived from Greek words meaning ‘maker of water.’
- Hydrogen | H (Element) - PubChemHydrogen was first recognized as a distinct element by Henry Cavendish in 1766. Composed of a single proton and a single electron, hydrogen is the simplest and most abundant element in the universe. It is estimated that 90% of the visible universe is composed of hydrogen. Hydrogen is the raw fuel that most stars 'burn' to produce energy.
- Hydrogen | H2 | CID 783 - PubChemHydrogen, refrigerated liquid (cryogenic liquid) appears as a colorless very cold liquid shipped in special heavily insulated containers.Boils at -442 °F. Contact causes severe frostbite. Hydrogen gas at normal temperatures is lighter than air but until vapors boiling off from the liquid warm up they are heavier than air. Very easily ignited. Burns with a pale blue, almost invisible flame.
- Hydrogen | History, Uses, Facts, Physical & Chemical CharacteristicsIsotopes of Hydrogen. There are three naturally occurring isotopes of hydrogen, named 1 H (protium), 2 H (deuterium), and 3 H (tritium). Protium is the most abundant hydrogen isotope (99.98%). Tritium is the most stable radioisotope and have a half-life of 12.32 years. All heavier isotopes of hydrogen are synthetic and are extremely unstable.
