Future technology hydrogen production

Grünbeck is your partner during the transition

Hydrogen Production Division

Water is a precious resource. This is precisely why at Grünbeck we have made it our business to provide it with its optimum quality and state. With our water treatment processes, we contribute to addressing unanswered questions, including those on the use of hydrogen. “Understanding water” together for a sustainable future.

With our new Hydrogen Production Division, we are helping to shape the energy transition towards a climate-neutral supply. Our systems there supply the purest water needed to produce green hydrogen by electrolysis.

Innovative technology, the highest quality and comprehensive service have earned us an excellent reputation with customers all over the world. We would like to expand our activities with you at this high level, especially those for the hydrogen economy. We offer many new perspectives for people with a wide range of profiles who want to contribute their skills to the sustainable shaping of the economy and society.

The element of the future!

Climate neutral with H₂ effect

Whenever there is talk of sustainable energy storage or CO2-neutral mobility, one element is usually not far away. With the atomic number 1, it is the lightest element we know and yet it has huge potential: hydrogen. As the energy source of the future, it is of paramount importance for achieving the objectives set as part of the energy revolution. Without this colourless gas, no green electricity will be stored, nor will there be any fuel cell-powered vehicles on our roads in the foreseeable future. For technology corporations, carmakers and the steel and chemical industries, hydrogen is currently the key technology for future developments.

The application of hydrogen

Power production: Stationary power supply with minimum performance losses

  • Regeneratively reproducible and flexibly applicable


Heat: Making optimum use of renewable energies and cogeneration

  • 40% of German CO2 emissions currently results from heat generation!


Mobility: Sustainable means of transport in all fields

  • Individual transport, public passenger transport, industrial trucks, road and rail freight transport etc.

Hydrogen as an energy source

  • High energy content: Combustion of 1 kg H2 = Combustion of approximately 2.75 kg petrol
  • Hydrogen H2 is available in virtually endless quantities
  • H2 is technically easy to produce from H2O
  • Storage and transport possible
  • Power-to-Gas: Making power storable by means of hydrogen
  • Environmentally friendly: no CO2 is produced when burning H
  • Hydrogen refuelling stations and H2 generation containers are not dependent on existing infrastructure


Grünbeck's role

Only the purest water is required for the electrolysis process. Other water-borne substances can lead to problems with the redox reaction. As a rule, water with electrical conductivity of < 0.1 µS/cm is required (fully demineralised water). Different methods are used depending on the manufacturer, which means, for example, that water treatment systems are required for additional fresh water feed or circulation treatment.
