This conference was established around seven years ago and is one of the most prestigious in the field. It aims to promote the dissemination of information related to various aspects of green ammonia: from public perception of the issue and communication, support infrastructures, transport, as well as technological developments. The last of these objectives is particularly in line with the aims of the GrAPHy project. Participating in this type of event is very important for keeping abreast not only of the latest technological developments, but also for establishing a more transversal view of the area, and therefore stimulating the developments planned for the GrAPHy project. In addition to the high-quality presentations, the conference also offers good networking opportunities.
