Geo-X: Generalised geospatial software for production of green commodities

Geo-X is an open-source geospatial optimisation tool designed to estimate the production costs of green commodities such as hydrogen and ammonia. Building on the GeoH2 model, Geo-X introduces a fully generalised structure that enables the integration of multiple renewable energy sources and diverse commodity production pathways. The software couples detailed techno-economic plant optimisation with spatially explicit assessments of transport and infrastructure, managed through a reproducible Snakemake workflow. Geo-X supports applications across data-rich and data-constrained contexts, providing transparent, extensible modelling for policymakers, researchers, and practitioners. Its capabilities are demonstrated for hydrogen and ammonia production in Ukraine and Ghana.
