Could diesel trains soon be a thing of the past? Change is coming, thanks to the further development of hydrogen technology. Using hydrogen as a power source for rail transport is a potential game-changer, for the future of sustainable mobility, especially for regional trains. But how do we bring this cutting-edge, climate-friendly power to a global train network, especially in areas which still rely heavily on traditional fuels to drive their railways? In the first episode of the second series of our Moving beyond podcast, host Prof. Sally Eaves speaks to Prof. Dr. Klaus Bonhoff, Head of Department for Policy Issues at the German Federal Ministry of Transport and Digital Infrastructure (BMVI), and Jochen Steinbauer, Platform Director H2 Technologies for Regional Trains at Siemens Mobility, to delve into the significant advantages of hydrogen technology and the decisive role it can play in the energy transition that is critical to the world today.
