Reaction: “Green” Ammonia Production
Ammonia production currently accounts for over 1.8% of the world’s consumption of fossil fuels and consequently over 1% of carbon dioxide emissions. The current production of ~180Mt/year is predicted to increase to ~270Mt/year by 2050 [1]; understandable given that over 80% of all ammonia produced...

| description | Ammonia production currently accounts for over 1.8% of the world’s consumption of fossil fuels and consequently over 1% of carbon dioxide emissions. The current production of ~180Mt/year is predicted to increase to ~270Mt/year by 2050 [1]; understandable given that over 80% of all ammonia produced is used for fertilisers. These predictions, combined with the requirement of net-zero carbon dioxide emissions for the 2°C scenario mean that there is an environmental imperative to decarbonise industrial ammonia production methods. Currently, steam methane reforming or (to a lesser extent) coal gasification are used to provide the hydrogen component of the syngas. Three possible methods are currently being considered to de-carbonisation the process namely: (i) conventional production with sequestration of the carbon dioxide, (ii) hydrogen production via electrification of water using renewable energies (wind, solar and tidal wave, etc) with adaptation of a small scale modified Haber-Bosch process as eHB, and (iii) development of alternative methods of production (i.e. electrochemical). While designing new ammonia plants with integrated carbon capture and storage (CCS) or retrofitting CCS to conventional plants does have notable potential, in this paper we will focus on the latter two other production methods mentioned above. The rationale for this is that, despite the fact that this method could play a part in production in the future, the cost of this method may be uncompetitive due to the dramatic falling cost of renewable energy. |
