Ecological Shortcomings OF Existing Methods for Substantiating the Number OF Gas Distribution Stations (GDS)

Gas distribution stations (GDS) are key components of regional and urban energy infrastructure, ensuring the reliable supply of natural gas to households, enterprises, and industrial facilities. However, existing methods for substantiating the number of GDS emphasize only technical and economic indicators, while overlooking ecological risks. This study analyzes the ecological shortcomings of current approaches, focusing on the age structure of operating GDS, routine gas losses, and associated emissions. Results indicate that 40% of GDS have been in service for over 30 years, contributing to higher risks of technical failures, leakages, and increased maintenance demands. Methane emissions from individual stations reach 2.5–3.7 tons annually, representing a significant climate impact, while hydrogen sulfide and mercaptans, though smaller in mass, affect local air quality and public health. The findings emphasize the need for integrated justification methods that combine technical reliability, ecological monitoring, and modernization strategies to ensure sustainable gas distribution.
