Speaking of the Future Cluster: Who is involved and what are you currently working on?
A good question, it’s not necessarily obvious at first. But you have to imagine that we have to detach our entire energy system and material flows, e.g. in the chemical industry, from fossil sources and hydrogen can step in here at many points, especially as an energy carrier. This means that from the production of green hydrogen to its storage, transport and use, there is a wide range of necessary components for the entire hydrogen economy, where AM can be used as a production technology. We are also trying to cover this breadth in the Future Cluster Hydrogen.
Can you explain, why hydrogen burns but water doesn’t?
Why does natural gas burn but carbon dioxide does not? In both cases, one is the combustion product of the other: Hydrogen burns, i.e. reacts with oxygen, to form water. This releases energy, which is why hydrogen can be used as an energy carrier. Incidentally, the same reaction takes place in total in the fuel cell, which then supplies electrical energy. In the electrolyser, the reverse reaction takes place: Water is split into oxygen and hydrogen.
At the DAP you’re the Area Manager, in your free time it’s more like Accordion Manager. Surely there’s a good story to go with that?
Apart from the fact that Stephan is convinced that I listen exclusively to “pan flute metal”? Although I play mostly Latin music on the accordion now, I used to play tenor horn when I was in school. At that time, my tenor horn teacher directed his students to the orchestra of the Cologne public transport company (KVB), where you could earn some extra money on top of your pocket money. We always wore uniforms with the KVB logo at the gigs, and that’s when I got to know the phenomenon of “uniform greetings” – even as a 14-year-old in uniform, every bus and train driver suddenly greets you!
