Hydrogen Solutions


Your partner for sustainable hydrogen generation

One of the most important challenges today is the decarbonization of the global economy. The key to meeting this challenge is to consistently expand renewable energy sources and integrate them in developed industry, energy, and mobility infrastructures.

We generate “green” hydrogen from renewable energy using PEM electrolysis, and in doing so make an important contribution to the global energy transition. The SILYZER product line helps you integrate fluctuating energy sources such as sun and wind in your process. 

We are setting the standards when it comes to sustainable hydrogen generation for the future. From planning and commissioning to operation, we support you as a reliable partner with a proven service concept tailored to your requirements.

Hydrogen – fuel of the future

Decarbonisation / Hydrogen

Renewable energy is playing an increasingly important role worldwide. It’s the backbone of a sustainable, CO2­ free energy sector, and thus a key technology for achieving decarbonization by the year 2100. Its share in global power generation is growing daily. But how can fluctuating energy sources such as sun and wind be integrated in existing grids, ongoing industrial processes, and flexible, individual mobility?

Hydrogen isn’t just the fuel of the future – it’s the fuel of the present!

Hydrogen is the most common element in the universe. Almost all of our chemical fuels are based on hydrogen, although in a bound form as hydrocarbons or other hydrogen compounds. To limit climate change caused by the global increase in CO2 emissions, solutions must be found for generating carbon­neutral and, therefore, sustainable fuels. This requires, among other things, that hydrogen is produced using renewable energy sources.

Use cases



About 90 percent of the more than 600 billion cubic meters of hydrogen produced annually worldwide is used by industry. Hydrogen is an essential chemical in industry that serves as fuel, additive, or reduction agent. Hydrogen is primarily used as a basic chemical in the synthesis of ammonia and other fertilizers such as urea, and for the synthesis of methanol, various polymers, and resins. Other major consumers in today’s hydrogen industry include refineries and the metalworking industry, as well as the semiconductor, glass, and food and beverage industries.



Only a small percentage of hydrogen is currently used in the energy sector, even though hydrogen is considered one of the most promising technologies in the large­scale integration of renewable energy. The more that electricity is generated from fluctuating renewable sources such as sun and wind and the less reliance there is on conventional power utilities, the more important it is that energy systems change. Ultimately, renewably generated power must also be available at times when sun and wind are scarce. This requires storing energy, including over extended periods of time. Hydrogen plays a key role as an energy source and storage medium. One example of a suitable infrastructure would be gas grids with their tremendous storage potential.

“Island solutions” can also be implemented using a hydrogen infrastructure. The highly dynamic behavior of a PEM electrolysis system is ideally suitable for direct connection to renewable power sources. Load peaks can thus be intercepted in the island grid and the energy can be fed back into gas turbines or fuel cells as needed.



The electrification of mobility is one of the greatest challenges in global decarbonization. Hydrogen can help to decarbonize this in two ways. Fuel cell vehicles can use hydrogen directly. Instead of CO2 and NOx, they pro­duce only water. Together with battery­powered vehicles, they not only reduce emissions from local urban traffic but also from interurban traffic and light and heavy­duty transport, because these vehicles have a significantly higher range than that of exclusively battery­powered vehicles – plus it takes only three minutes to refuel.

The second way hydrogen can help is through the synthesis of hydrocarbons from sustainable hydrogen and carbon from agriculture and forestry. In this way, even sectors with high fuel requirements, such as the aeronautics and shipping industries, can be decarbonized.
