Study visit in Finland brought new insights on methane emissions
Researchers in the MEQAL project visited the Finnish research institute Ruukki to learn about their work on measuring methane emissions. The visit provided new insights and ideas for the project, as well as opportunities for collaboration on equipment.
The MEQAL research project, funded by the EU through Aurora-Interreg, is developing new methods to detect and quantify methane leaks from, for example, recycling sites and wetlands. From Mid Sweden University, project leader Göran Thungström participated, together with project partners from the University of Oulu: Anssi Mäkynen, Katri Kukkola, Harri Juttula, and Ville Kaikkonen.
– This was a very rewarding visit that gave us both new knowledge and concrete ideas for our continued work in the MEQAL project, says Göran Thungström.
Methods for measuring methane gas
During the visit, Ruukki presented its equipment for measuring methane emissions from peat extraction sites and land areas. Several different models were demonstrated, based on chambers that measure a defined surface area over time. Calculations can then determine how much methane is released into the atmosphere, and also analyze the relationship between methane and carbon dioxide emissions.
The visit also highlighted the importance of long-term measurement series – in some cases, decades of data are required to draw conclusions about the development of methane emissions from wetlands.
– We received clear examples of how to practically measure methane emissions. In addition, there is now the possibility for our partners in Oulu to borrow equipment from Ruukki for their measurements, explains Göran Thungström.
Next steps in the MEQAL project
Following the study visit, the project work continues in its different areas. At Mid Sweden University, researchers are developing surface chemical sensors, while the University of Oulu is creating optical methods using drones to measure methane emissions across larger areas. In Rovaniemi, a test field is being built where methane emissions can be tracked with both drones and autonomous vehicles, so-called “sniffers.”
– Right now, we are still at the lab level, but it is incredibly valuable that our universities combine our expertise and collaborate, says Göran Thungström.
About the project
The Aurora Interreg project MEQAL is a collaboration between Mid Sweden University, the University of Oulu, and the University of Lapland in Rovaniemi. The project’s main goal is to develop new methods for detecting and quantifying methane leaks. In the long run, the technology could also help identify and address leaks to reduce emissions.
