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 explained - U.S. Energy Information Administration (EIA)
Hydrogen is an energy carrier 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 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.

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 - 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 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.
Why Hydrogen Is So Unique in Chemistry - sciencenewstoday.org
Hydrogen is the simplest atom possible: one proton, one electron, and, in its most common form, no neutrons. This simplicity might suggest predictability or even boredom. But don’t be fooled. Because of its simplicity, hydrogen is also the most sensitive to the subtleties of quantum mechanics.
Hydrogen - MIT Climate Portal
Hydrogen is the lightest chemical element and the most abundant chemical substance in the universe. Using fossil fuels or clean electricity, we can produce hydrogen gas, which can be stored, transported, and burned to provide power.
Hydrogen (H) - Definition, Preparation, Properties, Uses, Compounds ...
What is Hydrogen? Hydrogen is the simplest and most abundant element in the universe, consisting of just one proton and one electron. This lightweight, colorless gas is found in great abundance in stars and gas giants and is a fundamental building block in the chemistry of life.
Hydrogen - Energy Education
Hydrogen plays an incredibly large role in the workings of stars, but is also of vast importance on the Earth. It is rarely in its free state on Earth, instead it combines with many elements to form molecules that are important for life.
