Risø DTU is the National Laboratory for Sustainable Energy at the Technical University of Denmark (DTU), one of Europes leading research laboratories in sustainable energy and a significant player in nuclear technologies.

Risø DTU has large test facilities and interdisciplinary research environments that enable to solve problems across traditional professional boundaries and competences. It has 700 employees, of which 130 work in the Fuel Cells and Solid State Chemistry Division, with 20 persons directly involved in electrolysis research, development and testing.


The Fuel Cells and Solid State Chemistry Division carries out research and development on functional ceramics for energy technologies, with Solid Oxide Fuel Cells (SOFC) as the main research topic. Other research areas of interest are high temperature electrolysis (Solid Oxide Electrolyser Cells, SOEC), high temperature alkaline electrolysis (AEC), ceramic gas separation membranes, electrochemical flue gas purification, batteries, and magnetic cooling.

The division has been involved in SOFC research for more than 20 years and has considerable know-how in the development and testing of materials, cell components, fuel cells and electrolysis cells and stacks. The team holds world-class expertise in the areas of hydrogen generation, electrolysis and fuel cells.

The division facilities include a test laboratory for fuel cells and electrolysis of more than 500 m2 and a pre-pilot production line with a capacity of several tens of thousands of solid oxide cells per year.


Main contribution to WP5 leading the evaluation of electrolysis technologies suitable for offshore deployment and resistant to the marine environment and WP6, on safety systems and procedures.

Additional participation in WP1 and WP11.
