Australian exploration company Gold Hydrogen has achieved a significant milestone by successfully flowing, separating, and purifying helium during testing at its Ramsay 1 well on South Australia’s Yorke Peninsula. The development marks an important step in the company’s strategy to commercialize natural hydrogen and helium resources from the Ramsay Project.
Since flow testing began on 25 July, the company has recorded air-corrected helium purity levels exceeding 30%, while stabilized air-corrected purity has remained around 19%. Air-corrected helium purity represents the actual helium concentration in the produced gas after removing the effects of atmospheric contamination, providing a more accurate assessment of the gas stream's quality.
The Ramsay 1 well has been operated at its planned pumping capacity of up to 2,000 barrels of fluid and gas per day. Helium extracted from the gas stream has been processed through a purification system supplied by Canadian industrial gas equipment company Quantum Technology. Following purification, the helium has been compressed and stored in onsite cylinders for further evaluation.
According to Gold Hydrogen, this is the first successful surface concentration of helium in Australia since the Darwin helium plant ceased operations in late 2023. The company considers this achievement a key technical validation for future commercial production.
Ramsay 1 will now serve as the designated reinjection well throughout the remainder of the 2026 exploration campaign. Operational data collected from the well will support engineering decisions and help optimize production strategies across the broader Ramsay Project. Managing Director Neil McDonald stated that the successful testing provides valuable operational experience and confidence in the equipment before zonal testing begins at the Ramsay 2 and Ramsay 3 wells.
The company also plans to significantly expand testing at Ramsay 3 using a larger pumping system capable of processing up to 20,000 barrels of fluid and gas per day, representing a tenfold increase in testing capacity.
Gas samples collected from Ramsay 1 will undergo detailed analysis through a collaborative research program involving Australia’s Commonwealth Scientific and Industrial Research Organisation (CSIRO) and Oxford University to better understand reservoir characteristics and gas composition.
Gold Hydrogen noted that the gas stream primarily consists of helium, nitrogen, and naturally occurring hydrogen. In 2024, the company reported discovering hydrogen with a purity of 95.8% across seven separate zones while also confirming helium resources. Based on current estimates, the project could contain up to 1.3 million tonnes of natural hydrogen and approximately 96 billion cubic feet of helium.
Further strengthening its commercialization strategy, Gold Hydrogen signed a non-binding memorandum of understanding with Mitsubishi Gas Chemical in June 2026 to jointly conduct a staged pre-feasibility study for methanol production. If sufficient natural hydrogen resources are confirmed, the partners intend to advance toward a definitive feasibility study and front-end engineering design for a future commercial facility.
Impact on Product and Chemical Commodity Prices
The successful purification of helium and continued confirmation of high-purity natural hydrogen strengthen the commercial outlook for industrial gases, hydrogen-based chemicals, and future green methanol production. Increased domestic helium availability could improve supply security for semiconductor, medical, aerospace, and research industries while supporting Australia's industrial gas sector. For chemical commodities tracked by ChemAnalyst, the immediate price impact is expected to remain limited because the project is still in the testing and pre-commercialization phase. However, successful scale-up could gradually ease long-term helium supply constraints and improve hydrogen feedstock availability, potentially supporting more competitive pricing for hydrogen-derived chemicals and methanol over time.
