With hydrogen you can store, transport and provide renewable energy from for example, sun and wind. The technology is used worldwide today to store solar and wind power, to make homes self-sufficient in energy and to make vehicles completely free of harmful emissions. By using hydrogen together with fuel cell technology, you get exhaust-free vehicles and buses where clean water is the only emission.

  • Hydrogen consists of two hydrogen atoms and has the chemical designation H 2
  • Hydrogen is both the most common and the lightest element
  • At room temperature and normal pressure, hydrogen is gaseous
  • The energy density is high per unit of mass, but low per unit of volume for uncompressed hydrogen.
  • The latter makes it challenging to store and transport hydrogen efficiently
  • The most common ways to store hydrogen are either in compressed form at 200–700 bar or in liquid form, which it assumes at -253 degrees Celsius
