Using Aqueous Ammonia in Carbon capture and CO₂ abatement

by | Oct 13, 2025

As industries across the UK and beyond work toward Net Zero goals, finding efficient and scalable methods to reduce carbon emissions has become a major focus. One area showing significant promise is carbon capture using aqueous ammonia — a process that not only helps remove CO₂ from emissions but also enables the creation of valuable by-products such as fertilisers.

Aqueous Ammonia as a CO₂ capture solvent

Aqueous ammonia, such as Aquamonia 245 (24.5%) and Aquamonia 330 (33%) from Blended Products, is being studied and adopted as an effective solvent for post-combustion CO₂ capture. When introduced into flue gas streams, ammonia reacts with carbon dioxide to form ammonium carbonate and bicarbonate compounds. This process efficiently absorbs CO₂, offering a lower-energy alternative to conventional amine-based systems.

Turning captured Carbon into value

One of the major advantages of using aqueous ammonia is its ability to convert captured CO₂ into value-added products. The absorbed carbon can be processed to produce ammonium sulfate or ammonium nitrate — both of which are widely used as nitrogen-rich fertilisers. This approach not only prevents greenhouse gas release but also supports the circular economy by transforming emissions into useful materials.

Supporting a sustainable future

With growing research and investment into ammonia-based carbon capture, Aquamonia from Blended Products provides a reliable, high-purity solution for pilot studies and industrial-scale applications. Available in multiple concentrations and pack sizes, it supports manufacturers, researchers, and energy producers seeking to make carbon capture more sustainable and cost-effective.
