Hydrogen technologies

hähn hydrogen offers you a range of selected products around hydrogen.

This ranges from hydrogen production in electrolysers to energetic use in fuel cell systems and material use in power-to-X plants or synthesis plants.

You will also find gas generators for the production of oxygen and nitrogen. For inerting, nitrogen plays an important role in work on H2 systems; detached from hydrogen technology, however, our gas generators are also used in some other industries, for example in the beverage and food industry or in hospitals.

Energy centers and waste heat recovery

We plan and build individual energy centers. Our services include engineering and, if desired, complete delivery and installation with additional services such as maintenance and repair. Operation is possible through contracting models.

Benefit from our comprehensive know-how in the field of energy. 

The following technologies are used by us:

  • Waste heat utilization e.g. via ORC plants
  • Heat pumps
  • Geothermal plants
  • Temperature storage media
  • Combustion plants (solid fuel firing, combined heat and power plant, boiler plant, gas turbines)
  • Waste
  • Biomass
  • Fossil fuels e.g. gas, oil
  • Hydrogen
  • Renewable energies
  • Steam plants
  • Power-to-X
  • Emergency power plants (mobile and stationary)
  • Compressed air supply
  • Refrigeration supply plants
  • Fuel infrastructure / tank farms

Our experience ranges from small projects to plants of 100 MW.

Mobile or semi-stationary plants can be designed as container plants.
