A cumulative H2 potential of 20 mg/g TOC is reported from open system pyrolysis experiments on organic matter. The dataset, associated with a 2022 journal article, examines hydrogen generation across Paleozoic maturity suites from Australia and additional marine source rocks from Europe and the USA. It includes kinetic parameters constructed by subtracting hydrogen associated with hydrocarbon formation from total hydrogen.
Use Cases
- Modeling hydrogen generation kinetics based on vitrinite reflectance ranges of 3.5–5.0%
- Comparing hydrogen yields between terrigenous and marine source rocks based on described porosity differences
- Estimating regional hydrogen resources based on inferred yields per unit rock volume for formations like the Patchawarra Formation
Strengths
- Data is derived from open system pyrolysis experiments and high-resolution mass spectrometry
- Includes analysis of specific geological formations (Permian Patchawarra Formation, middle Cambrian Arthur Creek Formation) and basins (Cooper, Georgina)
- Provides a calculated global in-place accessible H2 estimate of ~3.5E+10 tonnes
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
- Data may reflect geographic bias inherent to the selected Australian, European, and USA source rocks
