Purpose and goal
The climate crisis demands renewable energy without CO₂ emissions. Renewable energy needs energy storage. Green ammonia can store energy efficiently. Superstate has a patented method to produce green NH₃ directly from air and water, through the electrolysis of a Li-salt. The method is scalable, energy efficient and enables local ammonia production with fossil-free electricity. The goal is to give e.g. farmers access to NH₃ for electricity, heating and operation of machines in a sustainable way.
Expected effects and result
Superstate´s method for green ammonia production at room temperature has three steps: electrolytic formation of the catalyst from a "salt", nitriding of the catalyst, and the third step is decomposition of the nitrided catalyst to form ammonia At the end of Etapp I, the optimized process and specifications for the components to be supplied to build a demo pilot for Etapp II. Optimized energy storage conditions will also be delivered to meet the customer´s energy needs.
Planned approach and implementation
Manually driven, flexible mini reactor will be built to vary tests conditions in terms of solvent, “salt concentration”, cathode/anode interaction, amperage/voltage measurements, gravimetry tests, samples probes accessibility, pressure variations with focus on safety and reliability will be built, based on CAD-models. The sustainability will be evaluated with mass spectroscopy and IR/UV methods and gravimetry analyses. The governing criteria are the energy efficiency, safety, and sustainability.
