Abstract

Ammonia has raised its profile to become a potential fuel for the near and long future in applications such as marine engines, boilers, furnaces and even large gas turbines. Although the chemical suffers some disadvantages compared with currently used fossil fuels in terms of flame speed and ignition delay time, it is also known that ammonia can be fully combusted under the right conditions, whilst also increasing its reactivity when either doped with other agents or reacted at high temperatures. These features make ammonia a good candidate not only to distribute hydrogen but also to use it directly as a fuel, hence reducing conversion inefficiencies and maximising the energy embedded in such a chemical. However, it is critical to raise awareness in the issues carried out when ammonia is employed for such purposes, thus providing potential users of a well-informed assessment of the possible use of ammonia as an energy vector. Along those lines, this chapter briefly addresses current case studies, national projects and international agendas that attempt to decode the best methods to use ammonia as a combustion fuel, aiming at providing evidence of ongoing efforts to maximise energy efficiency, stranded resources recovery and an entire mitigation of unfriendly emissions, all important parameters for the progression towards a net zero economy supported by ammonia combustion.
