Hydrogen

Also Known As H2
Energy Carrier

The lightest element, used in energy systems as a carrier rather than a primary source: it must first be made, today mostly from natural gas and increasingly by electrolysis of water using renewable electricity. Hydrogen burns and reacts in fuel cells without carbon emissions at the point of use, which put it at the center of plans to decarbonize steelmaking, fertilizer, shipping and long-term energy storage.

First Commercial Year
2014 2
Marks the Toyota Mirai, launched in Japan in December 2014, the first mass-produced hydrogen fuel cell vehicle sold commercially. Hydrogen fuel cells had earlier non-commercial and niche industrial/aerospace uses (for example NASA spacecraft), but this is the first commercial sale of hydrogen as an energy source to ordinary buyers.

Ammonia, Energy Sources

Ammonia is a leading candidate hydrogen carrier (17.6 wt% hydrogen by mass), central to IEA's Future of Hydrogen analysis of storing and transporting hydrogen as ammonia.

Electrolyzers produce hydrogen rather than consume it; the association is production, not use.

  • Hydrogen explained
    generally presents as two hydrogen molecules (H2)
  • Associated With: Energy Carrier, What is energy explained, Sources of energy
    Both types of energy can be used as primary energy sources (an energy source in its original form) to produce useful energy such as heat, or they can be used to produce secondary energy sources such as electricity and hydrogen.
