Sustainability has become one of the greatest scientific challenges of our time. Redesigning the chemical value chain with sustainable reactions and non‐fossil feedstocks, closing cycles in energy storage and digitalization demand interdisciplinary scientific excellence. The summer school organized by the early career researchers groups of Germanys reaction engineering and catalysis community aimed to bring together young scientists from reaction engineering and catalysis with experts from industry and academia to work on sustainable chemistry, energy storage and digitalization. During three days of lectures, workshops and intensive group work, the hot topics of our time were discussed and seminal ideas to tackle current challenges were formed.
