NoNOx filter
Collaboration with VolkerWessels to reduce nitrogen emissions
In March 2023, Groningen Airport Eelde launched a pilot with the NoNOx filter, an innovation from VolkerWessels capable of reducing up to 99 per cent of nitrogen oxide emissions from diesel engines. During a six‑month test period, the filter was applied to a Ground Power Unit (GPU) used to supply aircraft with electrical power on the ground. This collaboration aligns with the airport’s ambition to achieve emission‑free ground operations by 2030.
We are ready!
This project is complete and will not be updated further. For questions, please contact the project manager.
Project Results
- The NoNOx filter was installed on a diesel‑powered Ground Power Unit for testing.
- Emissions data were collected before and after the filter's installation.
The NoNOx filter directs the GPU’s exhaust gases through a filter medium that captures nitrogen oxides and converts them into harmless gases such as water vapour. The filter activates at GPU start‑up and heats up via exhaust gases, after which it automatically begins reducing emissions.
Role of Groningen Airport Eelde
Groningen Airport Eelde served as the pilot test location and was responsible for monitoring and evaluating the system within daily operations. The airport used this project to investigate how existing equipment can be made more sustainable, as part of the broader NXT Airport programme.
