Green Ammonia Applications
Existing Uses - Where Green Ammonia Can Be Used As Replacement Of Grey Ammonia
Fertilizers
o Nitrogen is an essential element and a much-needed source of nutrition for growing plants. Ammonia has the highest N content of any commercial fertilizer.
o Around 80% of global ammonia produced is currently used in the production of fertilizers. At present, all ammonia used as a fertilizer is produced by burning natural gas (and therefore can be referred to as grey ammonia).
o With growing concerns over its environmental impact, there is enough attention to the idea of using green ammonia instead of grey ammonia in the agricultural sector.
Industrial sector
Direct Application
In direct application, ammonia is directly applied as fertilizer to plants instead of converting it to other nitrogen fertilizers. This application involves using highly pressurized liquid ammonia as fertilizer. This liquid ammonia turns to vapour on direct application to soil
Indirect Application
Ammonia is first converted to other nitrogen-based fertilizer compounds. These include urea, ammonium nitrate, calcium ammonium nitrate (CAN), urea ammonium nitrate (UAN), mono- ammonium phosphate (MAP), di-ammonium phosphate (DAP), and others
o In industrial sector, the applications of ammonia include use in explosives, refrigerants, plastics, textiles, dyes, and chemicals, etc.
o The advent of carbon-free ammonia and the increased push to reduce the carbon footprint globally across industries can lead to an increase in industrial demand for
ammonia.
o There is interest from large mining companies to invest in carbon-free inputs, which means that green ammonia, upgraded into nitrates explosives, might be of interest.
Several green ammonia projects in countries with substantial mining industries plan to use green ammonia to produce nitrates. This is the case in Australia and Chile;
however, the market is still small in Europe.
o There is interest from producers of Acrylonitrile and Caprolactam, which are used to produce synthetic fibers. There might be increasing interest in developing a carbon-
free source of fibers, for the production of clothing and furnishings.
o Ammonia is also increasingly used as a NOx reagent (i.e., a reagent to reduce Nitrogen Oxide from a combustion process) in Selective Catalytic Reduction (SCR) systems.
SCR systems are emission control systems that are installed in large stationary sources of NO2, particularly coal power plants. The same system can be used to scrub NOx emitted from some of the potential new users of green ammonia, such as ships and power plants.
