Description
Large-scale geological CO₂ storage faces a critical but underestimated constraint: subsurface pressure buildup from injection can progressively limit storage capacity over time, yet most climate-policy frameworks, including IAMs, still rely on static capacity estimates that ignore this dynamic. The authors introduce CO2LOGIX, a computationally efficient model that simulates pressure evolution under different CO₂ injection growth scenarios. Applied to a UK case study, the model shows that unmitigated pressure reaches its upper limit after 83 years, with near-term storage rates still falling short of recommended targets. Faster growth scenarios worsen the problem, shrinking available capacity or requiring costly mitigation. The study calls for incorporating realistic pressure feedbacks into IAMs, and positions CO2LOGIX as a practical tool for managing pressure constraints in large-scale CCS deployment.
