Kyros Hydrogen Solutions was, within the hydrogen network Hypos, a member of the project ELKE, which aims to develop high performance and cost-effective electrode structures for alkaline electrolysis.

The project sought to reduce the investment costs of alkaline electrolysis from 1,000 €/kW to 700 €/kW. To this end, ELKE worked on an improved manufacturing process that enables continuous coating of the electrodes. In addition, the performance parameters were better adapted to regenerative electricity by using a new combination of materials. The effectiveness of the adaptations was first analysed and mechanically characterized using 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.
