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

Abstract

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 (CO 2 ) 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.
