The use of ammonia in fuelling applications has been recognized as a method to support energy transition towards a zero-carbon economy. Ammonia, a chemical that contains large quantities of hydrogen, can be employed in applications that go from furnaces to aerospace engines. However, handling, power outputs, emissions and maintenance procedures still need to be properly defined before ammonia can substitute fossils in the production of energy. Therefore, this chapter presents four attempts in which ammonia has been employed to replace fossil fuels for powering purposes. From theoretical studies to technological developments, the chapter focuses on the challenges that each case faced whilst highlighting the novelties that the research groups developed to overcome those constraints. The experience gained over studies and developments combined with unique selection methods have enabled the progression of these ideas and rigs, establishing them as first demonstrators worldwide, thus providing the first insights into the complexity and potential of using NH3 as a fuel.
