Home > Glossary > Hydrogen


Hydrogen is the simplest and most abundant chemical element in the universe, represented by the symbol H and the atomic number 1. In standard conditions for temperature and pressure, hydrogen exists as a colorless, odorless, non-toxic, and highly combustible diatomic gas (H₂). It is notable for its high energy content per unit mass, which makes it a potential fuel source, particularly in the context of energy commodities in the form of hydrogen gas, liquid hydrogen, and various hydrogen compounds.

In the context of energy commodities, hydrogen is increasingly viewed as a key component of a future low-carbon economy. It can be produced from a variety of resources, such as natural gas, nuclear power, biomass, and renewable power like solar and wind. Depending upon the source and method of production, hydrogen can be classified as “gray” (from fossil fuels with CO2 emissions), “blue” (from fossil fuels with carbon capture and storage), or “green” (from renewable sources with no associated CO2 emissions). It is used in a range of applications, from fuel cells for electric vehicles to industrial processes and heating.

Here are two references for further information on Hydrogen:

1. U.S. Department of Energy (DOE) – Office of Energy Efficiency and Renewable Energy:
This site provides an overview of hydrogen and its potential uses as a clean energy source, including its role in fuel cells, the various methods of hydrogen production, storage, safety, and more.

2. International Energy Agency (IEA):
The IEA’s page on hydrogen outlines its importance in the transition to a clean, secure, and affordable energy future. The site details the global status of hydrogen production, market developments, policies, and the technology outlook.

Please note that while I ensure the links were active and relevant at the time of writing this description, I cannot guarantee they will remain permanently accessible, as web content can change.
