Molecular Hydrogen Generation from Organic Sources in Geological Systems

Data from a study published in the Journal of Natural Gas Science and Engineering in 2022, hosted by the Australian Ocean Data Network. The dataset likely contains results from pyrolysis experiments and analyses of Paleozoic and Cretaceous rock samples from Australia, Europe, and the USA. It focuses on thermogenic hydrogen generation potential, kinetic parameters, and porosity characteristics across different source rock types.

Use Cases

• Modeling hydrogen generation kinetics based on reported pyrolysis experiments and adjusted kinetic parameters.
• Estimating regional hydrogen resource potential based on the reported cumulative H2 potential of 20 mg/g TOC and per-unit-volume yield calculations.
• Comparing porosity development for hydrogen storage between marine and terrigenous source rocks based on SEM-scale observations described.
• Correlating hydrogen generation pulses with vitrinite reflectance maturity ranges (3.5–5.0%) across different organic matter types.

Strengths

• Includes specific quantitative findings, such as a cumulative H2 potential of 20 mg/g TOC and a global in-place accessible H2 estimate of ~3.5E+10 tonnes.
• Analysis covers a range of source rock types and organofacies from multiple basins (Songliao, Cooper, Georgina, Europe, USA).
• Links experimental pyrolysis data with microscopic observations (SEM-scale porosity) for storage implications.

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 study basins.
