New solutions for precise and reliable emission measurements
Ambitious goals to mitigate climate change and improve air quality are part of everyday work in the energy sector, maritime transport, aviation, and the development of non-road mobile machinery. New engines, fuels and exhaust aftertreatment technologies enable low emissions, but measuring them is challenging.
The METECH project develops precise emission measurement technologies that can reliably detect gaseous and particulate pollutants harmful to climate and air quality. The methods under development must function not only in laboratories but also in demanding field conditions.
Researchers at Tampere University’s Aerosol Physics Laboratory focus particularly on measurement techniques for particle emissions.
“Measuring small particles is a key focus of our researchers. This is closely tied to understanding the significance of gas–particle conversion and the phenomena of secondary particle formation,” says Professor Topi Rönkkö, Head of the Aerosol Physics Laboratory at Tampere University.
The three‑year METECH project has a budget of 1.6 million euros. The project is part of Wärtsilä’s WISE Veturi programme, and is funded by Business Finland.
Reliable measurements support the transition to cleaner technologies
In addition to reducing greenhouse gases and climate impacts, it is essential to decrease health risks by improving air quality. The project focuses on measuring methane (CH₄), nitrous oxide (N₂O), ammonia (NH₃), sulfur dioxide (SO₂), ultrafine particles, and black carbon.
Accurate emission measurements are crucial for reliably verifying new technologies and fuels, and for enabling companies to meet tightening emission limits, reporting obligations, and emissions trading requirements. The project supports the transition toward a pollution‑free future while creating international business opportunities for Finnish equipment manufacturers.
“We support this work by ensuring consistency between field and laboratory measurement results,” Rönkkö adds.
The METECH project is coordinated by VTT. In addition to Tampere University, the partners include Finnish Meteorological Institute, Wärtsilä Finland Oy, Proventia Oy, Gasmet Technologies Oy, Dekati Oy, Pegasor Oy, Airmodus Oy, Helsinki Region Environmental Services Authority (HSY), AGCO Power Oy and Maurus Oy.
