The third Progress Meeting was held from 31 May to 1 June 2022. The meeting was attended by all HEETII project Partners. Thanks to the very good organisation of the meeting by SWE we were hosted by Zamecek Petrovice. During the meeting 7 presentations were given about the project progress, dissemination, communication, conclusions from TGK1 meeting as well as problems and plans for tasks realisation. It was preliminarily agreed that the next meeting will take place at the end of 2022 and will be organised by GIG as coordinator of WP4.
