Topsoe and DTU Collaborate on Next-Generation Electrolysis Cells for Green Transition

As the Technical University of Denmark and Topsoe continue their long-standing collaboration, they are paving the way for a significant part of the green transition through the development of electrolysis cells for use in power-to-x processes. Their joint efforts have led to the creation of highly efficient electrolysis cells, which convert electricity from renewable sources into hydrogen using water. This crucial step in the power-to-x process is essential for replacing fossil fuels with climate-friendly alternatives, particularly in heavy traffic, shipping, and the production of plastics, paints, and medicines.

Key Takeaways:

• The collaboration between DTU and Topsoe has resulted in the development of highly efficient electrolysis cells using Solid-Oxide Electrolysis Cell (SOEC) technology, which requires 25% less power to convert electricity into hydrogen compared to other technologies.
• The electrolysis cells developed by Topsoe and DTU are based on a 20-year-old collaboration, starting with fuel cells, which were later transformed into electrolysis cells as the energy agenda shifted towards a greener future.
• The researchers have gained significant knowledge about the basic theory of SOEC electrolysis cells, but are working to gain a deeper understanding of the individual processes and materials within the cells to improve their performance and durability.
• Topsoe is building a factory in Herning to produce electrolysis cells, with the goal of having it operational by 2025, and is collaborating with DTU to optimize the cells through modeling, design, testing, and development of new materials.
• The researchers predict that the new generation of electrolysis cells will be produced at the factory in Herning in 7-10 years, after thorough testing and validation of the cells' potential.

Statistics:

• The electrolysis cells developed by Topsoe and DTU require 25% less power to convert electricity into hydrogen compared to other technologies, resulting in significant energy savings and reduced material usage.
• The collaboration between DTU and Topsoe has been ongoing for over 20 years, covering various fields, including fuel cells and electrolysis cells, and is the company's largest investment to date.
• The number of sub-laboratories at DTU's laboratory, dedicated to researching electrolysis cells, is five, with two used for manufacturing and three for characterizing various conditions in the cells.
