In CO₂ storage the predicted plume and pressure front are the regulated asset — they drive the permit, the monitoring plan, the 45Q credit and decades of liability. So mesh quality isn’t cosmetic. Buoyant CO₂ is an unstable, fingering displacement that structured grids tend to suppress and under-predict, while a true Voronoi mesh keeps flux faces orthogonal and limits grid-orientation and dispersion error — making that fidelity routine instead of a special study.
The biggest lever is schedule. A Class VI permit’s Area of Review is delineated straight from flow simulation, and those permits have historically taken years. Turning a geomodel into a qualified mesh in hours lets an operator delineate the AoR faster and re-run quickly every time the regulator asks for a revision — pulling first injection forward. At roughly 1 Mt/yr against the $85/t 45Q credit, a single year of acceleration runs on the order of $10M+.
The rest is risk. Because credits and liability ride on the modeled plume, better, more consistent meshing means defensible capacity and injectivity estimates, less exposure to credit clawback, and fewer surprises that trigger re-permitting. And because randomized Voronoi meshes make ensembles cheap, you can put real confidence intervals on whether CO₂ reaches a monitoring well and when — the probabilistic, defensible statements regulators and credit buyers increasingly expect. It removes a well-defined class of numerical error; it doesn’t claim to erase geologic uncertainty.
