Recently, ammonia is regarded as an alternative fuel without carbon dioxide (CO2). Numerous studies have been performed using ammonia as a fuel. Iki and Kurata confirmed the working of a prototype for the ammonia gas turbine, where ammonia burned in an environmentally benign way to generate electricity, exhausting only water and nitrogen [1]. From the view of cycle of ammonia for the development of a society with low carbon, it is required to synthesize carbon-free ammonia (green ammonia) in small plants. This green ammonia can be synthesized using renewable energy, with hydrogen from electrolysis of water and nitrogen from pressure…
