During his PhD studies, Morten Linding Frederiksen investigated how novel electrode materials can enhance the efficiency of alkaline water electrolysis. His research focused on how different elemental compositions and fabrication methods influence electrode performance and cost-effectiveness in the production of green hydrogen. By combining experiments conducted under both controlled laboratory conditions and industrially relevant environments, Morten achieved efficiency improvements of up to 16%.

These findings provide new insights into electrode performance and degradation mechanisms under real operating conditions, highlighting the importance of bridging laboratory-scale electrochemical studies with tests under practical industrial conditions.

The PhD study was completed at Department of Biological and Chemical Engineering, Faculty of Technical Sciences, Aarhus University.

This summary was prepared by the PhD student.
