General char​acteristics

Hydrogen is ​a colourless, tasteless and odourless gas. Hydrogen has a very low density, being 14.38 times lighter than air. It is flammable in a wide range of concentrations and burns with a colourless to slightly bluish flame. Hydrogen has a high calorific value (120 MJ/kg).

Basic quali​ty parameters

The quality of hydrogen for use in mobility is specified in ISO 14687 and EN 17124.
