A 2022 study analyzes thermogenic hydrogen generation from organic matter in source rocks from the Songliao, Cooper, Georgina, and other global basins. The research uses high-resolution mass spectrometry and open-system pyrolysis experiments to model hydrogen generation kinetics and estimate global resources. The dataset likely contains results from these experiments, including hydrogen potential and maturity parameters.
Use Cases
- Modeling hydrogen generation kinetics based on vitrinite reflectance and organic matter type described in the study.
- Estimating regional hydrogen resources based on the reported cumulative potential of 20 mg/g TOC and global in-place estimates.
- Comparing hydrogen storage potential in marine versus terrigenous shales based on described porosity differences.
- Calibrating pyrolysis experiments using the kinetic parameters constructed from hydrocarbon and hydrogen yield adjustments.
Strengths
- Analysis is based on experimental data from multiple global basins, including the Permian Patchawarra and middle Cambrian Arthur Creek Formations.
- Quantifies a cumulative H2 potential of 20 mg/g TOC and identifies a main generation pulse in the vitrinite reflectance range 3.5–5.0%.
- Provides a concrete global resource estimate of ~3.5E+10 tonnes of in-place accessible H2.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
