Molecular Hydrogen Generation from Organic Sources in Geological Systems

Research data on thermogenic hydrogen generation from organic matter in source rocks, including samples from the Permian Patchawarra Formation in Australia and other global basins. The study indicates a cumulative H2 potential of 20 mg/g TOC and estimates ~3.5E+10 tonnes of in-place accessible H2 globally. Data originates from the Australian Ocean Data Network and is associated with a 2022 journal publication.

Use Cases

• Modeling hydrogen generation kinetics based on vitrinite reflectance ranges (3.5–5.0%) described in the study.
• Comparing hydrogen yields from different source rock organofacies (Type-II marine vs. Type-III terrigenous) mentioned in the description.
• Estimating regional hydrogen resources based on the per-unit-rock-volume yields inferred for formations like the Patchawarra Formation.
• Analyzing the relationship between secondary porosity in marine shales and hydrogen storage potential as discussed.

Strengths

• Data is linked to a peer-reviewed journal article (Journal of Natural Gas Science and Engineering, 2022).
• Description provides specific quantitative findings, including a cumulative H2 potential of 20 mg/g TOC and a global resource estimate of ~3.5E+10 tonnes.
• Analysis covers multiple geological basins and source rock types (e.g., Permian Patchawarra Formation, middle Cambrian Arthur Creek Formation).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Description metadata is limited; actual data quality requires manual inspection after download.
