This presentation describes a comprehensive case study focused on natural hydrogen seepage within the Yilgarn Craton, Western Australia. The study employed an array of field techniques, including soil gas sampling, headspace gas analysis, and surface water analysis, aimed at understanding the distribution and characteristics of hydrogen seepage in this region. By exploring various field techniques, we aimed to uncover the intricate patterns and dynamics of hydrogen release from the geological formations of the Yilgarn Craton. Additionally, this research presents a comparative assessment of passive versus pumped long-term monitoring techniques to determine their respective efficacies and advantages in monitoring hydrogen seepage over extended periods.
In addition to field studies, the research included laboratory analysis of soil desorption to provide critical insights into hydrogen release mechanisms from the soil matrix. The integration of both field and laboratory studies enhances our comprehension of the natural hydrogen seepage phenomenon, shedding light on geological processes and their potential implications for resource exploration. The findings from these combined field and laboratory efforts provide valuable data on natural hydrogen seepage, contributing to a better understanding of geological processes and potential implications for resource exploration.
