In addition to the future import of the hydrogen carrier ammonia, decentralized ammonia plants are needed that can efficiently produce green ammonia from fluctuating renewable energy on a small to medium scale. In the future, ammonia farms can cover peak loads and achieve economic operation at an intermediate number of full-load hours of use. In addition, a higher security of supply and independence from imports can be achieved. In the CAMPFIRE implementation project, a new type of ammonia farming system for plant outputs of up to 150 MWel is being developed in a subproject of the partners Zentrum für BrennstoffzellenTechnik (ZBT), Karlsruher Institut für Technologie (KIT), Universität Rostock, Leibniz Institut für Plasmaforschung und Technologie (INP) and the automatisation & software GmbH. For this purpose, a Haber-Bosch reactor is being developed which, with the aid of a falling temperature profile, enables the efficient conversion of nitrogen and hydrogen to ammonia at lower pressures than in current large-scale plants. In addition, new catalysts are being used that have a precious metal content, but this is being reduced through innovative core-shell approaches in order to strive for cost reduction. To generate them, the partners developed a new synthesis process based on the application of an atmospheric plasma in liquid starting materials such as salt solutions and ethanol (PiL — Plasma-in-Liquid). In this process, catalyst suspensions can now be generated within minutes. The partners fulfilled an important milestone of the subproject by successfully completing a first plant design for an ammonia farm for an electrical power of 15 kW for the conversion of 500 g H2 into NH3 per hour. This design will serve as the basis for the upscaling and implementation of the reactor for an output of 200 kWel in the following project phase.
