CO2LOGIX: First-order model of pressure-constrained CO2 geological storage growth at the basin scale

The UPTAKE monthly webinar series returns, continuing its engaging discussions on carbon dioxide removal (CDR) technologies and the latest research developments. The next session in the series, dedicated to recent publications on CDR research, will focus on the paper CO2LOGIX: A first-order model of pressure-constrained CO2 geological storage growth at the basin scale. Speaker: Iain de Jonge-Anderson, University of Strathclyde Moderator: Catrin Harris, Utrecht Univerity Panelist: Samuel Krevor, Imperial College 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.
