| Popis: | 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. |
