Amminex Emissions Technology was founded in 2005 based on fundamental research carried out by a group of scientists at the Technical University of Denmark (DTU). The group consisted of five scientists with a background in chemical engineering, chemistry and physics. Together they developed a unique way of storing and transporting ammonia safely and at high density in a salt.
Ammonia is widely known as an ideal reagent to remove toxic NOx gasses because it reacts with them creating water and harmless nitrogen. Amminex core innovation lies in designing an innovative solution that is capable of providing ammonia in a new and far more effective way to diesel vehicles that are equipped with Selective Catalytic Reduction (SCR) catalysts.
An SCR catalyst is an advanced emissions control technology that works together with a reductant agent in the exhaust system to clean the exhaust from a diesel vehicle. Currently, the most widespread and used reagent is a liquid based ammonia solution that sets off a chemical reaction converting NOx into nitrogen and water. In city driving this technology has a number of physical limitations. At low exhaust temperatures for example - typically in cold weather or when diesel vehicles move slowly through congested traffic– extra fuel is needed to keep dosing active. This adds cost, increases CO2 emissions and also means the system often does not reduce sufficient NOx at the very time when it is needed the most.
Leveraging the breakthrough research results achieved in 2005, Amminex has developed a technology platform named ASDS™ that is capable of storing gaseous ammonia in a solid material that is carried onboard the vehicles, and dosing this into the exhaust stream. This material is created through a reaction of strontium chloride and ammonia and offers a number of distinct advantages compared to conventional technology.
ASDS™ unlocks the full potential of the SCR catalyst by dosing gaseous ammonia into the exhaust stream – also at low temperatures. This enables a high level of NOx reduction in all real-life driving conditions and climates with no compromises in fuel efficiency or CO2 emissions. In addition, ASDS™ also has other key benefits. For example, the density of ammonia in the solid material is twice as high as in the liquid based ammonia solution which doubles the possible driving range between refilling of the reagent. Furthermore, since ammonia is released to the exhaust stream as a gas, no deposits occur in the exhaust system. This translates into less maintenance and vehicle down-time compared to conventional liquid based technology.
Mature business partner
Since it was founded, Amminex has experienced fast growth having changed from a smaller research based company to a commercially mature company with all relevant business partners in place to meet customer expectations. The technology has been validated on a variety of diesel vehicle types including busses, light commercial vehicles and passenger cars. This has proven the reliability and operational performance of the technology and its ability to nearly eliminate NOx emissions from diesel vehicles regardless of driving conditions and climate. Adding to this, Amminex now also has strong operational track-record from large scale commercial implementation of ASDS™.
Amminex Technology currently employs 46 people and is headquartered in Søborg near Copenhagen, Denmark. The company also operates a a 6.500 m2 state-of-the-art volume production facility located in Nyborg, Denmark. The main shareholders of Amminex Emissions Technology are Faurecia, SEED Capital and Nordea-fonden.
