Abstract

The potential environmental impacts of CO2 leakage from carbon capture and storage (CCS) sites remain a critical concern for the long‐term viability of CCS technologies. Soil microbial communities, which regulate essential biogeochemical processes, are particularly sensitive to changes in soil CO2 concentrations. In this study, controlled CO2 release experiments at two depths, 2.5 m (shallow subsurface) and 0.5 m (near‐surface) in a field setting in Eumseong, South Korea, were conducted in 2016 and 2017, respectively, to evaluate soil microbial and biogeochemical responses to elevated CO2 exposure. In the 2.5‐m depth experiment, despite substantial CO2 enrichment at 60‐cm soil depth (peaking at 21.2%), minimal CO2 accumulation occurred at the surface (15‐cm depth:
