The flood disaster in Germany, the extreme heat and the forest fires in parts of southern Europe and not least the latest report of the Intergovernmental Panel on Climate Change make it clear once again that we must reduce our CO2 emissions quickly and drastically. This requires a lot of electricity from renewable sources, also for the production of hydrogen by electrolysis of water. Many sectors of the economy are relying on this green hydrogen for their climate-friendly conversion. It can even be used to convert CO2, which cannot be avoided, into methanol as a fuel and basic material for the chemical industry - in technical jargon called Carbon Capture and Use, or CCU for short.
Robert Schlögl, Director of the department Heterogeneous Reactions talked about where the hydrogen for the upcoming transformation can come from and how useful CCU techniques are.
