Hydrogen - Department of Energy
Hydrogen is the most abundant element in the universe; it is also the simplest and the lightest. Although hydrogen constitutes nearly 75% of all the universe’s matter, only a small fraction of the hydrogen accessible on Earth exists in a pure state (not bonded to other elements).
Hydrogen | History, Uses, Facts, Physical & Chemical Characteristics
Hydrogen is one of the three most abundant elements present on Earth. It was discovered in 1766 by Henry Cavendish and is widely used for various industrial, medical and recreational purposes.
What is hydrogen? | National Grid
Hydrogen is a clean alternative to methane, also known as natural gas. It's the most abundant chemical element, estimated to contribute 75% of the mass of the universe. Here on earth, vast numbers of hydrogen atoms are contained in water, plants, animals and, of course, humans.
Hydrogen explained - U.S. Energy Information Administration (EIA)
Hydrogen is a gas at normal temperature and pressure, but hydrogen condenses to a liquid at minus 423 o F (-253 o C). Energy carriers transport energy in a usable form from one place to another. Elemental hydrogen is an energy carrier that must be produced from another substance.
Hydrogen | H (Element) - PubChem
Hydrogen is the raw fuel that most stars 'burn' to produce energy. The same process, known as fusion, is being studied as a possible power source for use on earth. The sun's supply of hydrogen is expected to last another 5 billion years. From the Greek word hydro (water), and genes (forming).
