“How to bring innovative ideas and products from the lab to the engineering scale?” is a crucial step of the transition to a future sustainable energy system. Various examples of recent up-scaling cases, covering different technologies and materials were presented during the second workshop of the Energy Materials 4 Innovation (EM4I), organised by the EERA Joint Programme on Advanced Materials and Processes for Energy Applications (JP AMPEA), together with the EERA Joint Programme on Nuclear Materials (JP NM) and the transversal Joint Programme Digitalisation for Energy (tJP DfE).
