Hydrogen can originate from various geological processes and its ability to migrate to near-surface layers makes soil gas analysis crucial for identifying subsurface accumulations. Current methods using portable analysers are often insufficient for precise determination, highlighting the need for gas chromatography in controlled laboratory settings. Hydrogen's high mobility and chemical reactivity make it difficult to maintain stable soil gas samples from collection to analysis. To address this challenge, an exper...

In the context of the urgent need to combat climate change, renewable energy sources, such as geothermal energy, play a crucial role in reducing greenhouse gas emissions. This study examines the ecological impact in the form of avoided emissions for five geothermal heating plants located in Poland. The analysis included emissions of CO2, SO2, NOx, CO, benzo(a)pyrene, and particulate matter (PM10 and PM2.5), considering three reference scenarios based on conventional fuels: hard coal, high-methane natural gas, and ...
