The University of Lund hosted a 2-day technical meeting (20th – 21st April 2023). The focus of the meeting were the upcoming tasks in the main technological work packages (WP2, WP3 and WP4) and their Research & Development activities, as well as small scale “real-life” experiments. WP1 and WP5 debated their ongoing work, as well as synergies and links between the work packages. Face-2-face meetings are particularly useful to discuss the links between the work packages, but also to take a step back and look at the big picture. The technical presentations provided great insights and opened further questions to be considered over the next few months.
