This document, D5.2 Symposium Report, is a deliverable of the SUNRISE CSA, which is funded by the European Union’s H2020 Programme under Grant Agreement No. 816336. On February 3rd – 7th, 2020, a series of meetings were organized in Brussels by the SUNRISE consortium, partly in collaboration with Energy-X and the Representation of the State of Hessen to the EU. The week started on February 3rd – 4th with a closed consortium meeting at EERA to finalize the work on the SUNRISE deliverables. On February 5th – 6th, the formal kick-off of SUNERGY took place, the follow-up initiative of the CSAs SUNRISE and Energy-X. At this event over 100 stakeholders of both CSAs gathered for a series of public sessions on February 5th and 6th following a high-level lunch event at the European Parliament on February 5th and ending February 6th noon. February 6th pm and 7th am were spent on public SUNRISE meetings at EERA to collect input for the SUNRISE blueprint, deliverable D1.3.
