MADE IN THE USA
Hydrogen (H) being the lightest element is the most abundant element in our universe (70%). Most hydrogen on earth exists in molecular forms such as water and organic compounds.
It is being used in liquid form (LH2) or as a colorless and odorless gas (H2) in many sectors such as petrochemistry, energy, mobility or production.
Since gaseous hydrogen combined with oxygen (O2) can form an explosive gas mixture (oxyhydrogen), most applications are subject to special safety pre-cautions regarding fire and explosion protection.
Many possibilities and potentials of hydrogen technology have only been developed and opened up in recent years and today play a key role in climate-neutral energy generation & storage.
