NOx Abatement in EU and How Much GreenChem Contributes

  • AdBlue
  • GreenChem
  • SCR

A brief overview

Nitrogen oxides (NOx) are a group of highly reactive gaseous compounds containing nitrogen and oxygen in different proportions, namely NO, NO2, and N2O. NOx is a byproduct of the combustion processes such as those used in power generation and road transport. It can cause serious health problems and is a major contributor to human-induced climate change.

To reduce concentrations of air pollutants in Europe, from the beginning of the 1990s, the EU introduced a series of directives and regulations, commonly called Euro standards, which prescribe limits for emissions of a range of pollutants, including NOx.

The EU’s NOx abatement regulations are designed to reduce NOx emissions from various sectors such as industrial, automotive, farming activities, and more. In 2020, road transport was the principal source of NOx, responsible for 37% of emissions in the EU.

Since the regulations were introduced, the EU’s commitment to NOx abatement has significantly reduced NOx emissions. It is also key to note that total emissions of NOx fell by 48% between 2005 and 2020. These figures show that the implementation of NOx abatement measures has positively reduced NOx emissions in the region, providing cleaner air for its citizens and helping to protect the environment.

Since 1990, total NOx emissions have steadily declined in all industries, including transport.

How GreenChem products contribute to DeNOx-ing our environment

We offer solutions that help industries reduce NOx emissions and comply with EU regulations. AdBlue is a unique product designed to be both efficient and affordable. By using our products, users of many sectors can significantly improve their environmental performance while also protecting their bottom line. It is safe to say that by using AdBlue, you have already put your mark on removing NOx from the atmosphere.

How much NOx does GreenChem help to remove yearly?

Using rounded molecular weights of Urea (60) and Nitrogen Oxide (30) in the overall NO reduction reaction results, in theory, 1 ton of Urea reduces 1 ton of NO, and thus 3 tons of AdBlue reduces 1 ton of NO.

The above figures are based on the assumption that NO reduction reaction has 100% efficiency. In reality, this is not the case, as reduction reactions rarely reach total efficiency. With modern SCR technology, it is proven that 90% efficiency NO conversion is well within reasoning. Therefore, we can assume that our efficiency is at least 90%.

GreenChem’s position

Based on the above ratio and the realistic efficiency, we can easily calculate the amount of NOx reduced by GreenChem’s AdBlue in the automotive segment using GreenChem’s total AdBlue sales. According to internal data, GreenChem’s AdBlue sales in the automotive segment have been on a steady rise, at levels of which we have consistently helped to remove more than 250,000t a year of NOx since 2021.

Below is the official overall data for NOx emissions provided by the European Environmental Agency (EEA). The latest statistics available are for 2020.

Conclusion

Nevertheless, even with a certain level of tolerance, GreenChem’s contribution to NOx abatement in Europe in an order of magnitude 250 000t NOx per annum is not unrealistic.

The quantity of NOx reduced by GreenChem’s AdBlue and resulting conclusions are based on chemical reaction methodology and calculation, not real experimental measurements. Thus, absolute accuracy has to be taken with caution. In conclusion, NOx abatement is not just an obligation but an opportunity to contribute to a cleaner and healthier future. With the right measures in place, the EU can continue to reduce its NOx emissions while also helping to create jobs and boost economic growth. At GreenChem, we are proud to play a part in this important endeavor and to help our clients become more sustainable. Together, let’s make the environment cleaner.
