The focus of the Fifth Meeting of the Advisory Board on March 11, 2021 was on our project teams CF04 Solid State Ammonia Synthesis, CF06_1 Ammonia Reactor and CF06_2 Ammonia Plant. The project partners presented recent results in the development of thin films, catalysts and reaction technology as well as system modelling of electrolysis processes, micro-Haber-Bosch processes and innovative synergetic plants for the seasonal production of green ammonia from renewable energies to the advisory boards. Other discussion points included the future CAMPFIRE Open Innovation Lab located at the industrial site of YARA GmbH & Co KG at the Rostock Poppendorf. Many thanks to the members of our advisory board for their reliable support and trustful cooperation.
