Leak detection with linear soil gas sensors under field conditions — First experiences running a new measurement technique

摘要

A 400 m2 soil test field with gas injection system was built up, which enables an experimental validation of linear gas sensors for specific applications and gases in an application-relevant scale. Several injection and soil watering experiments with carbon dioxide (CO2) at different days with varying boundary conditions were performed indicating the potential of the method for, e. g., rapid leakage detection with respect to Carbon Capture and Storage (CCS) issues.
