20 mg/g TOC cumulative hydrogen potential is found from organic matter in Lower Cretaceous shales of the Songliao Basin. The dataset likely contains results from open system pyrolysis experiments on Paleozoic maturity suites from Australia's Cooper and Georgina Basins, and mature marine source rocks from Europe and the USA. Kinetic parameters for thermogenic hydrogen generation were constructed by subtracting hydrogen associated with hydrocarbon formation.
Use Cases
- Model hydrogen generation kinetics based on vitrinite reflectance ranges of 3.5–5.0%
- Estimate regional hydrogen resources based on yields per unit rock volume
- Compare hydrogen storage potential based on porosity differences between marine and terrigenous shales
- Assess global in-place accessible hydrogen resources based on the reported ~3.5E+10 tonnes estimate
Strengths
- Cumulative hydrogen potential of 20 mg/g TOC is quantified
- Kinetic parameters were constructed from open-system pyrolysis experiments
- Analysis includes specific geological formations like the Permian Patchawarra Formation and 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
