Prof. Oluf Jensen (Department of Energy Conversion and Storage, DTU) – Hydrogen, from romance to solution
Jens Oluf Jensen has materials science, electrocatalysis and electrochemistry as main research fields. The approach is experimental, addressing technologies within energy conversion with a focus on hydrogen energy, high temperature PEM fuel cells and alkaline water electrolysis. He was awarded his PhD degree for a study on metal hydrides. The research on fuel cells and electrolyzers includes ion conducting membranes (acidic and alkaline), catalysts (noble metal based and noble metal free), electrode structures and cell testing with an emphasis on durability. He coordinates the development of low temperature electrolysis at DTU Energy and is the founder of the conference series International Conference on Electrolysis. He teaches hydrogen energy and fuel cells as well as thermodynamics at DTU and at Joint European Summer School (JESS). He is a board member of Hydrogen Denmark, the national Danish organisation for hydrogen and Power-to-X, and editorial board member of the journals Electrocatalysis and Molecules (Electrochemistry Section).
For a century, the narrative of hydrogen as an energy carrier has flourished in all it beauty and simplicity. However, the immediate fascination of the cleanliness of the energy cycle based on the purest of all resources, water, has been held in check by a reality of cost and immense infrastructure challenges.
Today, we have reasons to believe that the balance is about to change in favour of hydrogen. The terms “hydrogen economy” and “hydrogen society” may still be too absolute, but the need for conversion and storage of energy as part of the green transition of the global energy system appears inevitable and hydrogen has a central role to play here.
The presentation will review the status for the early roll-out of electrolysis and power-to-X in Denmark and it will give examples of ongoing electrolyzer development at DTU Energy.
If traditional alkaline electrolysis is proven but clumsy, PEMFC elegant but with scaling limitations and SOEC efficient but late, then why not combine the best of the present electrolyzers in one or more game-changing technologies.

Jan Torgersen (NTNU) – Topologically Optimized Electrochemical Energy Converters: Geometry driven performance optimization from Nano to Microscale
Jan Torgersen is Professor of Mechanical Engineering at the Norwegian University of Science and Technology (NTNU) and Visiting Professor of Mechanical Engineering at Stanford University. He is part of the Outstanding Academic Research Fellow Program and NTNU and the director of the Micro- and Nanoscale Design laboratory. Torgersen studied Mechanical and Industrial Engineering at the Vienna University of Science and Technology (TU Wien), where he joined the Institute of Materials Science for his Master and PhD. He was instrumental in the structuring hydrogels with two photon polymerization, a high resolution lithography based additive manufacturing technique capable of fabricating 3D features over multiple length scales. In his post-doctoral work at the Nanoscale Prototyping Laboratory at Stanford University, he worked on energy conversion and storage devices such as thin film capacitors for DRAM applications, buffer layers for solar cells and catalytic layers for fuel cells. At NTNU Trondheim, he continues to work on the interplay between surface functionality and topology, where his current research interests lie in biomedical materials and energy conversion devices.
With unprecedented freedom in design, additive manufacturing technologies provide us with the capabilities to leverage from geometric complexity. If properly exploited, this allows us to design performance instead of geometry, where the latter is not user defined but a result of a computer optimization. This approach is heavily utilized for light weighting in aerospace, where high stiffness saves material usage and costs. After a quick dive into the field of topology optimization, similar approaches will be presented for the design next generation of electrochemical energy converters. In a journey from the nanometer to the centimeter scale, we will first tackle activation losses showing results on how to optimize the composition and the shape of Pt particles deposited on carbon coated membranes rendering ORR mass activities of 0.8 A mgPt−1 @0.9 V iR-free. Further, the transport in GDLs may be optimized by disregarding manufacturing constraints with theoretically to two to three orders of magnitude increases in permeability and ohmic conductance. Theoretical considerations on water management will also be given. For the realization of carbon lattices, we will show initial achievements on fabricating ordered carbon lattices with resolution in the 10 µm regime and total dimensions over several cm. This work can be transferred into all similar materials systems that involves porous electrode structures which depends on efficient transport, high surface area and minimized usage of materials, such as titanium microstructures, where initial results will be shown. The area of ordered structures with predictable and optimized performances might pave an entirely research and development field relevant for low cost and high-performance electrolysis. We are soon evaluating if the predicted performances can be validated in electrochemical measurements.
