Ancient rocks may hold a faster, cheaper path to low‑carbon energy. We sit down with Dr Krista Davies, Managing Director of Prominence Energy, to unpack how the Gawler Craton’s hot granites, iron‑rich rocks, and deep crustal faults create multiple natural hydrogen “play types” across a massive 64,000 km² land position in South Australia. Krista brings three decades in oil and gas and a pioneering PhD in natural hydrogen to explain, in plain terms, why white hydrogen and helium could reshape heavy industry and unlock new export opportunities.
We walk through the exploration strategy from the ground up. First comes low‑impact soil gas and water bore sampling to detect subtle seepage signatures of hydrogen and helium, providing cost‑effective field validation across broad terrain. Then we integrate those anomalies with structural models to pick the smartest seismic lines, image reservoir and seal configurations, and rank traps before drilling. It’s a disciplined, geology‑led approach that turns a district‑scale thesis into drill‑ready targets while preserving capital and minimising surface disturbance.
Beyond the rocks, we map the market. Hydrogen demand today is big but emissions‑heavy; natural hydrogen offers a discovery‑and‑produce pathway that could lower costs and accelerate adoption for green steel, heavy transport, and industrial heat. Proximity to the Spencer Gulf, Whyalla’s industrial hub, and mining centres near Olympic Dam strengthens the case for local offtake and future export. We also dig into helium’s rising strategic value for MRI, semiconductors, and data centre cooling—an opportunity made sharper since Australia became a net helium importer. If exploration confirms accumulations of both gases, helium can enhance project economics and resilience.
We close with a clear 2026 roadmap: complete the geochemical survey on PEL 803, integrate insights to focus seismic in the second half, then advance a risk‑ranked portfolio toward drilling next year. If you care about energy transition, critical minerals, and practical paths to decarbonisation, this is a grounded, data‑driven look at what could be Australia’s next energy chapter.
