Hydrogen - Wikipedia
Hydrogen is a chemical element; it has the symbol H and atomic number 1. It is the lightest and most abundant chemical element in the universe, constituting about 75% of all normal matter. Under standard conditions, hydrogen is a gas of diatomic molecules with the formula H2, called dihydrogen, or sometimes hydrogen gas, molecular hydrogen, or simply hydrogen. Dihydrogen is colorless, odorless ...
Hydrogen | Properties, Uses, & Facts | Britannica
Hydrogen, 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 Energy Explained: Everything You Should Know
Hydrogen energy is emerging as a key clean fuel in the global move toward sustainability, offering the potential to decarbonise industries, transport and energy systems. This article, brought to you by the Renewable Energy Institute, an accredited provider of renewable energy education and training, provides an accessible overview of hydrogen; how it works, its advantages and challenges and ...
Hydrogen - Department of Energy
Hydrogen 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 - Thermophysical Properties - The Engineering ToolBox
Hydrogen is not toxic but is a simple asphyxiate by the displacement of oxygen in the air. Under prolonged exposure to fire or intense heat the containers may rupture violently and rocket. Hydrogen is used to make other chemicals, in petroleum refining and in oxyhydrogen welding and cutting. The phase diagram of hydrogen is shown below the table.

Hydrogen Factsheet - Center for Sustainable Systems
Hydrogen is a feedstock and energy carrier used in multiple sectors. Global hydrogen demand reached 97 Mt in 2023, a 2.5% increase from 2022, with 10 Mt in the U.S.1,2 Hydrogen is the most abundant element in the universe, but is present in limited amounts in elemental form on Earth. The primary production method (globally and in the U.S.) is steam methane reforming (SMR) of natural gas (NG ...
