Many projects across the world are looking to radically reduce the GHG costs of producing ammonia by using renewable electricity for hydrolysis, rather than the energy & natural gas intensive Haber-Bosch process.  This could reduce the GHG costs of N fertiliser, but the real drivers come from using ammonia in the energy chain.

Interesting piece from Alzbeta Klein from International Fertiliser Association (IFA) about routes to decarbonising ammonia production -


Did you know that IFA is tracking more than 50 green ammonia projects?

IFA’s 2022 capacity survey indicated that of the green ammonia projects currently underway, 1.8 Mt of ammonia capacity could be commissioned by 2026. This would account for 0.8% of global capacity. However, there are many more projects in the pipeline. If all the projects currently being tracked by IFA were to materialize, it is forecast that green ammonia operations could total almost 60 Mt in 2028, accounting for 20% of the global total.


Ammonia was originally made from hydrolysis of water using cheap energy from hydroelectric power (HEP) - so for all intensive purposes it started off as green. The trouble was that splitting natural gas with the consequent carbon dioxide by-product was cheaper. Why not replace natural gas with biogas from AD as a substrate and combine with HEP? It would have much less GHG than use of manure based on a unit of food output.

Nitrogen is required annually by most crops (except pulses) to achieve yield and quality. Judging how much N to apply is a key part of nutrient management.

A range of products are commercially available that claim to enable more efficient nutrient uptake, allowing less nutrient to be applied as fertiliser.

Fertilisers, especially nitrogen, give some of the biggest environmental impacts of any inputs, from both their manufacture and their application.  A range of innovative approaches are being developed to reduce the energy costs, greenhouse gas emmissions and waste associated with the production of fertilisers.
