Development of performance-optimized and inexpensive electrode structures for alkaline electrolysis

Project goals

The aim of the project is to reduce the investment costs for alkaline electrolysis from the current € 1000 per kW to € 700 per kW in the future.

For this purpose, the project is working on an improved manufacturing process that should enable a continuous coating of the electrodes. Through the use of new material combinations the performance parameters are better adapted to renewable electricity. The effectiveness of the adjustments is first analyzed and mechanically characterized by imaging and spectroscopic methods and then tested in real operation.


Because of the close cooperation between research institutions and industrial partners, the project results can be directly integrated into existing systems. In the medium to long term alkaline electrolysis can be demonstrated as an important component of renewable energy storage systems.
