Project Overview: The Challenge of Nitrogen Emissions

Nitrogen emissions are a major concern for governments and companies worldwide. To effectively measure the emission, dispersion, and deposition of nitrogen compounds, the Netherlands Organisation for Applied Scientific Research (TNO) has developed advanced measurement methods and models. At the core of these projects is HealthyPhoton's HT8700 Atmospheric Ammonia Laser Analyzer, which has been successfully applied in TNO's mobile measurement vehicle, marking a significant milestone in mobile ammonia concentration measurement in Europe.

Introduction of HT8700 and Breakthroughs

The introduction of the HT8700 Atmospheric Ammonia Laser Analyzer enabled TNO to achieve mobile ammonia concentration measurements. This instrument, known for its high sensitivity and precision, allows real-time monitoring of ammonia concentrations in dynamic environments. Since its implementation two years ago, TNO has conducted a series of mobile measurement experiments using the HT8700, obtaining valuable data and insights.

First Mobile Measurement of Farm Emissions

In November 2023, as part of the Ministry of Agriculture, Nature, and Food Quality program, TNO conducted a major measurement campaign at a dairy farm. Using the HT8700 on a mobile measurement vehicle, TNO achieved the first-ever road-based measurement of ammonia emissions in Europe, examining the height and development of ammonia plumes. This provided an instant snapshot of farm emissions and crucial data to validate and improve emission models.

Data Analysis and Model Validation

With the high-precision data from the HT8700, TNO generated detailed 3D models of ammonia plumes and compared them with actual measurements. This process helped scientists validate the accuracy of their models and further understand the dispersion characteristics of ammonia plumes. These data are essential for improving models used to calculate ammonia deposition.

Future Outlook: Wider Applications

TNO plans to further optimize mobile measurement methods, making them simpler and more cost-effective. Supported by the HT8700 Atmospheric Ammonia Laser Analyzer, future mobile measurement vehicles will be able to quickly assess ammonia and methane emissions from farms and other sources nationwide. This innovative technology will be widely used not only in the Netherlands but also in international collaborations, such as with the French National Research Institute for Agriculture, Food, and Environment (INRAE) and the Flanders Research Institute for Agriculture, Fisheries, and Food (ILVO).

Conclusion

Through the application of the HT8700, TNO has made significant strides in nitrogen emission measurement and provided valuable experience and technical support for environmental monitoring and pollution control worldwide. HealthyPhoton remains committed to providing high-performance measurement equipment, supporting scientific research, and environmental protection efforts globally.
