Organic Matter Hydrogen Generation in Global Geological Basins

Research data analyzes molecular hydrogen generation from organic matter in mature source rocks. The study includes samples from the Permian Patchawarra Formation and middle Cambrian Arthur Creek Formation in Australia, plus mature marine rocks from Europe and the USA. It was published in the Journal of Natural Gas Science and Engineering in 2022.

Use Cases

• Modeling hydrogen generation potential using vitrinite reflectance values (3.5–5.0%) and kinetic parameters.
• Comparing hydrogen yields per unit rock volume between formations like the Patchawarra and Barnett Shale.
• Analyzing the relationship between organic matter type (Type-II, Type-III) and secondary porosity development for hydrogen storage.
• Estimating global in-place accessible hydrogen resources using reported calculations of ~3.5E+10 tonnes.
• Correlating hydrogen generation with specific geochemical metrics like cumulative H2 potential (20 mg/g TOC) and relative yields of CH4 and H2.

Strengths

• Data is derived from two distinct Paleozoic maturity suites and additional mature marine source rocks, providing a multi-basin perspective.
• Analysis includes specific maturity ranges (vitrinite reflectance 3–5%) and a quantified cumulative H2 potential of 20 mg/g TOC.
• Research methodology combines high-resolution mass spectrometry and extensive open-system pyrolysis experiments.

Limitations

• The dataset size, row count, and specific column structure are not provided in the source description.
• Sample data and raw data files are unavailable, limiting immediate analysis to the published findings.
• Geographic coverage is specific to studied basins in Australia, Europe, and the USA, not globally comprehensive.
