With H2 into the future
Because it's time to rethink!
More and more companies are taking responsibility for future generations by implementing sustainability into their strategies. This includes the use of renewable energies such as wind power and photovoltaics. To be able to use them regardless of the weather and time of day, green hydrogen serves as a valuable energy storage medium. Unlike fossil fuels, hydrogen (H2) is sufficiently available, but only in bound form (e.g., H2O). Research is continuously developing efficient and economical processes to separate these molecules.
In cooperation with companies and institutes, Haver & Boecker also contributes to finding solutions: Wire mesh is an important component of hydrogen production and use. Other areas of hydrogen technology also benefit from using this versatile medium. We are happy to support you in taking on individual challenges and finding answers. Because one thing is certain: green hydrogen always raises new questions.
Maximum efficiency is not only the ultimate goal when dealing with hydrogen but also the greatest challenge:
How can as much hydrogen as possible be produced and used with existing energy?
The answer lies in optimising every process of the hydrogen cycle and all the compounds involved - from the extraction of renewable energy to the purity of the water supplied.

Use of hydrogen
Whether in mobility as a component of fuel cells and fuel filters or in electrical engineering as explosion protection:
The advantages of wire mesh are also convincing when dealing with hydrogen.
Various processes are used to produce hydrogen (e.g., steam or plasma reforming).
However, it is electrolysis that leads to producing "green" hydrogen in the end:
Electrolysers split water into its components, hydrogen and oxygen. The electrodes form the heart of these electrolysers.
Wire mesh offers optimal conditions for this, as a component of the anode and cathode, to contribute to efficient and rapid hydrogen production.
Fuel cells are used in cars, aircrafts, and even ships as a source of electrical energy released during the chemical reaction of hydrogen and oxygen.
Many individual stacks form a powerful fuel cell. The thinner the cells are, the greater the number that can be accommodated in a limited installation space. This results in a higher output of electrical energy at the same time.
Hydrogen oxidises at the anode and gives off electrons. This is how the electric current is generated. Wire mesh with a catalyst coating forms the gas diffusion layer (GDL) in a fuel cell or the porous transport layer (PTL) in an electrolyser.
Refuelling a vehicle with hydrogen takes place under an enormously high pressure of up to 700 bar.
Therefore, the filter mesh that holds back impurities in the tank nozzle must be even more stable.
Robust wire mesh laminate has proven to be the ideal solution for this cone screen in the hydrogen tank nozzle.
Wire mesh prevents flashback into the supply line.
Important properties are temperature resistance and corrosion resistance to the hydrogen-air mixture. The material selection is based on such technical specifications as well as experience from comparable projects.
A multi-layer woven wire mesh pressed part is already being used successfully as explosion protection in electromobility and the chemical industry.
At the same time, wire mesh already ensures optimal heat distribution in heaters with its homogeneous pore structure. The pore accuracy of the mesh is crucial for using even valuable hydrogen efficiently and in an environmentally friendly way.
