Energy experts work to unlock natural hydrogen and helium
Gold Hydrogen was one of the first companies in the world to prove that high levels of both natural hydrogen and helium exist underground.
This has been achieved at its Ramsay Project on the Yorke Peninsula in South Australia, a 100% owned exploration project covering 75,000 sq km of permitted tenement (PEL 687).
The two sites drilled so far were identified after South Australian State Department geologists’ reports were uncovered from the 1920s and 30s. These showed natural hydrogen, which they had no use for back then, had been found while exploring for oil.
More than a century later, we have looked at these results with a new understanding that naturally occurring hydrogen could be the key to unlocking a revolutionary low-cost fuel source with huge implications for net zero carbon goals.

With a town in Mali, Africa, being powered by natural hydrogen for some years, we went back to the original South Australia petroleum test sites and had phenomenal results.
In 2023/24, we reported finds of natural hydrogen up to 95.8% purity and helium up to 36.9% purity. In a major boost to the company, traces of the extremely rare and valuable variant Helium3 were found in the latest samples.
Data from the two test sites has been matched with seismic and other survey results to identify up to five new sites that will be test drilled in 2025. The data suggests the latest targets are likely to record higher hydrogen and helium levels.
Successful results will lead to completion of a pilot project with the aim of commercialising both gases.
