What is the right energy mix for the energy system and mobility of tomorrow? “The energy system of the future must be powered by more renewable electrons and more renewable molecules,” explained Prof. Karsten Wilbrand vividly in his inaugural lecture at the TU Hamburg. In his lecture, the energy and mobility expert explained why he believes green electrons and molecules should be given priority today.
Large storage capacities
Renewable electricity from solar and wind power plays an essential role in decarbonizing the German energy system and making it independent of imports, the Shell mobility expert emphasized in his introduction. At the same time, however, the expansion of this inherently competitive sector, together with the necessary infrastructure, is limited. This is a good reason to bring renewable molecules such as hydrogen or hydrocarbons into play. “Unlike batteries, they have greater storage capacities, can bridge dark periods, and thus play an important role in the energy security and resilience of the energy system.”
Focusing on his area of expertise, the mobility sector, Wilbrand used a life cycle analysis of various car drive systems to impressively demonstrate how the right mix of green electrons and molecules – for example, through the correct use of plug-in hybrid vehicles – can contribute to a significant reduction in fuel consumption and CO2 emissions.
Appointment as professor
In fall 2024, TU Hamburg awarded Dr. Karsten Wilbrand the title of professor in accordance with Section 17 of the Hamburg Higher Education Act. The title is a special distinction that is only awarded for outstanding achievements comparable to those of a regularly appointed professor. Candidates often have strong practical experience, which complements their teaching perfectly. In this case, TU Hamburg is recognizing Karsten Wilbrand's outstanding achievements in the field of sustainable mobility solutions.
About the speaker
Karsten Wilbrand studied mechanical engineering with a specialization in energy technology at RWTH Aachen University and subsequently earned his doctorate at TU Hamburg at what was then the Institute for Thermal Power Plants and Marine Engineering. He began his professional career as head of the energy technology department at an international engineering and consulting firm for energy and environmental technology.
He has been with Shell since 2003, where he has held various technical and management roles. After heading fuel development in Germany and serving as global innovation manager responsible for strategic fuel research and development programs, he moved to his current position as Senior Principal Scientist for Mobility Technology in 2020. Since 2014, he has been a guest lecturer at the TU Hamburg, giving lectures on topics such as sustainable mobility and fossil and renewable fuels.
