Hydrogen 4.0

Hydrogen is an extremely flammable gas that is lighter than air

H2

Hydrogen 4.0 is used extensively in metal cutting and welding applications. It is also used to lift weather balloons to high altitude. Hydrogen molecules are small, making them ideal for leak detection. Hydrogen has a low viscosity and a high thermal conductivity making it ideal for filling inside turbo generators.

Uses

  • Component in welding mixtures
  • Metal cutting
  • Hydrogenation process for the production of margarine
  • Hydrodesulphurisation of fuel
  • Due to its small molecules, it is ideal for leak detection when used alongside hydrogen detectors
  • Prevents metal oxidation during heat treatment
  • Due to its low viscosity and high thermal conductivity, it is extensively used as a coolant gas in power generators
  • Fuel cells, eg for fuel cell electric vehicles
  • Lifting weather balloons to high altitude
