Materials for efficient hydrogen electrolysis
Name of the project
Green Hydrogen Production with Thermally Sprayed Nickel Cathodes in Water Electrolysis (in short: Hydro-NiCE)
Participants
CMMC GmbH; Sunfire GmbH; Chemnitz university of technology's chair of materials and surface engineering; Université de Technologie de Belfort-Montbéliard (France); Výzkumný a zkušební ústav Plzeň s.r.o. (Czech Republic)
Time frame
January 1, 2026, to October 31, 2028 (funded by the Sächsische Aufbaubank – Förderbank SAB)
Description
In the HydroNice project, CMMC is developing special aluminum-nickel alloys for various coating processes (HVOF, cold gas spraying, thermal spraying) and in different geometries for various atomization processes (atomization and gas atomization). This will result in a novel powder form that can be used as a high-performance cathode material in alkaline water electrolysis. The aim is to use special material design, innovative powder production, and thermal coating processes to create open-pored, highly active electrode surfaces that sustainably improve both the efficiency and stability of hydrogen production.
The focus is on combining defined weight proportions of aluminum and nickel so that the coatings perform at their best during hydrogen electrolysis. Any change in the chemical composition affects the melting temperature of the respective alloy and thus influences process stability and semi-finished product quality. For this reason, the specific material parameters are to be used in a simulation in such a way that a continuous casting process (continuous casting) is first virtually simulated and finally validated.
The project combines CMMC GmbH's expertise in the areas of materials and technology development and applies it in the best possible way.

Conclusion (ongoing)
With the help of the funding project, process parameters for coating using innovative nickel alloys will be made available. At the end of the project, the material can be produced for various fields of application using a continuous production process and an associated atomization process. The project thus makes a concrete contribution to increasing the efficiency of hydrogen production and to the industrial implementation of sustainable energy technologies.
