The need to promote an effective transition from an economy based on the intensive use of fossil fuels to another where the development criteria are based on sustainable processes that do not involve the generation of CO2 makes it necessary to develop new processes using the electricity generated from renewable sources as primary source of energy. This project, aims at developing atmospheric plasma technologies to induce chemical processes that are currently carried out through catalytic techniques. Specifically, FIREBOW pursues the development of a Gliding Arc Atmospheric Plasma reactor (GA) to induce three processes: (i) the synthesis of ammonia (NH3), (i) the production of hydrogen (H2) from NH3, and (iii) the decontamination of water. Both the experimental and theoretical characterization of the reactor, the latter carried out using computational methods, will be crucial for its correct operation and for the optimization of the proposed processes.
