Soil gas surveys for hydrogen and helium in New South Wales
<div>Exploring for the Future (2016-2024) was an Australian Government program led by Geoscience Australia (GA), in partnership with state and Northern Territory governments. The program aim was to drive industry investment in resource exploration in frontier regions of Australia by providing new precompetitive data and information about energy, mineral and groundwater resource potential.
To address this overarching objective, GA led a key element of the Australian Government’s commitment to achieve net zero by 2050. The energy transition to an ever decreasing carbon emission economy will involve the increasing use of hydrogen gas (hydrogen). The key benefit of using hydrogen is that it is a clean fuel, emitting only water vapour and heat when combusted. However, hydrogen today is manufactured at a relatively high cost. The recent discovery of a 98% per cent pure natural hydrogen field in Mali (Africa) has led to low cost hydrogen production. It has also captured the imagination of explorers and the search is now on for new natural hydrogen accumulations across the world. Australia is considered one of the most prospective locations for sub-surface natural hydrogen due to our ancient geology and potential presence of suitable hydrogen traps. A review of occurrences of hydrogen in natural sub-surface rocks found high concentrations of hydrogen in central western, New South Wales (NSW). Helium is extracted in commercial quantities from natural gas and Australia currently has no local production. This project, in collaboration with the Geological Survey of NSW (GSNSW), built on the desktop review and has identified new occurrences of natural hydrogen and helium through soil gas surveys in various locations across central and far west, NSW.
To support the Exploring for the Future program, six soil gas surveys for natural hydrogen and helium were jointly undertaken by staff from GA and GSNSW across central and western NSW during 2022-23. The project also included sites near the Tumut township to test various soil gas sampling techniques as well as the major focus in the Curnamona Province and Delamerian Orogen in far west New South Wales. In the first phase of the project, conceptual geological models for natural hydrogen and helium generation and accumulation were developed using pre-existing geoscientific data, including electromagnetic, magnetotelluric, magnetic, gravity, radiometric, drilling, seismic and satellite-derived data. The selected sites represented various concepts for natural hydrogen and helium generation, such as granite rocks rich in potassium, thorium, and uranium, banded iron formations, ultramafic rocks, and diatremes. The second phase of the project was the collection of soil gases from shallow (1 m deep) installations and subsequent molecular and isotopic compositional analysis at the GA Laboratory. Maximum hydrogen and helium concentrations in the soil gases are 309.5 ppm and 35.3 ppm, respectively, which is comparable to and even exceeds previously reported soil gas surveys both in Western Australia and overseas. The final phase was the integration of all datasets within a GIS platform for the interpretation and presentation of maps within this report.</div>

Geoscience Australia has led a key element of the Australian Government’s commitment to achieve net zero by 2050. This element is the adoption of hydrogen (H2) energy. The key benefit of using H2 is that it is a clean fuel, emitting only water vapour and heat when combusted. The recent discovery of a 98% per cent pure natural H2 gas field in Mali has captured the imagination of explorers and the search is now on for new natural H2 gas accumulations across the world. Australia is considered one of the most prospective locations for sub-surface natural H2 due to our ancient geology and potential presence of suitable H2 traps. A review of occurrences of natural H2 found high concentrations of H2 gas present in central western, New South Wales (NSW). This project, in collaboration with the Geological Survey of NSW, builds on that early work and identifies new occurrences of natural H2 through soil gas surveys in various locations across central and far west, NSW. Helium is also a strategic resource, being used by industrial, manufacturing, medical, recreational, research and space sectors. Currently helium is extracted in commercial quantities from natural gas. This document summarises the reconnaissance soil gas results obtained on molecular hydrogen (H2) and atomic helium (He) collected under the Exploring for the Future program. The purpose of the soil gas field studies was to collect samples and to document occurrences of geologic (natural) H2 and He in the Curnamona Province and Delamerian Orogen in far west New South Wales (NSW). The project also included sites near the Tumut township to test various soil gas sampling techniques. This project was a collaboration between Geoscience Australia (GA) and the Geological Survey of New South Wales (GSNSW), Department of Regional NSW. Its goal was to attract explorers to ultimately discover helium and natural hydrogen fields in this region
