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.
Hydrogen | Properties, Uses, & Facts | Britannica
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 refers to the use of hydrogen as a clean and versatile energy carrier which is capable of storing, moving and delivering energy produced from diverse sources such as water, fossil fuels or biomass to power vehicles, generate electricity and heat buildings.
Hydrogen - Department of Energy
Hydrogen has been described as the “Swiss army knife” of energy because it plays a key role in several sectors where there are limited or no viable alternatives (including in applications where electrification is particularly challenging or costly).
Hydrogen explained - U.S. Energy Information Administration (EIA)
Hydrogen can be produced, or separated, from a variety of sources—including water, fossil fuels, or biomass—and used as a source of energy or fuel. Hydrogen has the highest energy content of any common fuel by weight (about three times more than gasoline).

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.
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 | 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).
The Quest for Clean Hydrogen Moves Underground - The New York Times
The dream of clean hydrogen has tantalized energy experts for years, but producing it has been tough. Many start-ups think the answer could lie beneath our feet.
