Synthetic Underground Hydrogen Storage Measurement, Reporting and Verification Dataset (SUHS-MRV)

This Zenodo record publishes SUHS-MRV dataset content v2.1, a fully synthetic dataset designed to support early-stage Measurement, Reporting, and Verification (MRV) workflows for Underground Hydrogen Storage (UHS). The dataset represents cyclic hydrogen storage operations, including injection, withdrawal, storage balance, losses, hydrogen used as cushion gas in salt caverns, potential methane co-production in depleted gas reservoirs, and compression energy intensity. Records are provided at daily, monthly, and annual resolutions. The daily time step is a bookkeeping interval and does not imply daily operational cycling. All data are generated using deterministic, open-source Python workflows with a fixed random seed to ensure reproducibility. Values are illustrative and rule-based, derived from publicly available literature, and do not represent site-specific physics or operational measurements. Dataset fields are mapped to the Open Footprint (OFP) environmental data model and OSDU Well-Known Schemas (WKS) to enable schema-driven interoperability, MRV workflow prototyping, and digital integration testing across sustainability and subsurface data systems. The release includes CSV datasets, schema definitions, schema crosswalks, validation notebooks, and documentation. It is intended for research, education, and data-engineering use cases (e.g., MRV system development, schema testing, reservoir-type benchmarking) and is not suitable for regulatory, financial, or site-specific engineering assessments.
