Abstract
Implementation of geological CO2 storage requires monitoring for potential leakage, with an essential part being establishment of baseline CO2 in soil gas. CO2 concentrations and weather parameters were monitored for ∼2 years at three locations in the Netherlands. CO2 concentrations in soil ranged from 0.1 to 28% and were variable with site, depth and soil type. Statistical models (based on weather parameters) corresponded well with the measured CO2 time-series, having best fit with soil temperature. This method can detect large CO2 anomalies, however not smaller leakages. The monitoring method is robust and low-maintenance, making it a relatively low-cost surveillance possibility.
