Hydrogen Generation Potential From Mature Source Rocks

Research data analyzes molecular hydrogen generation from organic matter in geological systems across multiple basins. The study includes Paleozoic maturity suites from Australia's Cooper and Georgina Basins, plus samples from Europe and the USA, published in the Journal of Natural Gas Science and Engineering in 2022. Findings are based on high-resolution mass spectrometry and open-system pyrolysis experiments.

Use Cases

• Model hydrogen generation kinetics using vitrinite reflectance values and pyrolysis-derived kinetic parameters.
• Compare hydrogen yields per unit rock volume between formations like the Patchawarra and Barnett Shale.
• Analyze the relationship between organic matter type (Type-II/III) and secondary porosity development for hydrogen storage.
• Estimate regional hydrogen resources using cumulative H2 potential (e.g., 20 mg/g TOC) and rock volume calculations.
• Correlate hydrogen generation pulses with specific maturity stages (e.g., vitrinite reflectance 3.5–5.0%) across different basins.

Strengths

• Data spans multiple geological basins globally, including Australia, Europe, and the USA.
• Analysis includes specific maturity ranges (vitrinite reflectance 3–5%) and quantitative yield metrics (20 mg/g TOC).
• Methodology combines high-resolution mass spectrometry with extensive open-system pyrolysis experiments.

Limitations

• Sample size and specific row/record counts are not provided in the description.
• The dataset appears focused on mature source rocks, potentially lacking data from lower maturity stages.
• Column names and raw data structure are unknown, limiting direct analytical use.
