CO2 transport pipeline routing and CAPEX estimation for CCS infrastructure planning.
CO2GIS is an open-source QGIS plugin for planning CO2 transport pipeline infrastructure. It integrates raster-based least-cost path (LCP) routing with cell-level capital-cost (CAPEX) estimation, enabling optimal pipeline corridor selection under multi-criteria land constraints. The plugin implements the COMET cost surface framework, hydraulic pipeline sizing via the Darcy-Weisbach equation, and automatic booster station placement on long segments. Two estimation modes — precise cell-by-cell and fast point-sampling — let users tune the accuracy/speed trade-off. Requires the GRASS GIS provider bundled with QGIS.
