Gold Hydrogen Advances Toward Commercial Flow Testing at Ramsay Natural Hydrogen and Helium Project

Gold Hydrogen has released a detailed operational and commercial update outlining the company’s progress toward flow testing and potential commercialization at its Ramsay Project in South Australia, where multiple wells have confirmed naturally occurring hydrogen and helium. 

The presentation highlights the completion of the company’s 2025 drilling campaign, including successful drilling of Ramsay 3 and Ramsay 4, with hydrogen and helium detected across all four Ramsay wells drilled to date. Gold Hydrogen reported hydrogen purities of up to 97% and helium concentrations as high as 36.9%, alongside the detection of helium-3. 

A major focus of the update is the company’s upcoming June 2026 flow testing program, which is designed to assess reservoir deliverability, gas-water ratios, stabilized gas composition, and the potential for future contingent resource booking. The campaign is expected to test up to three wells over roughly 100 operational days. 

Gold Hydrogen says the project benefits from stacked hydrogen and helium-bearing zones, allowing selective extraction and potential co-production from a single well without compromising gas purity. The company also emphasized that commercially proven technologies already exist for dissolved gas extraction, helium separation, purification, and water reinjection — systems independently reviewed by Worley and widely used in Japanese dissolved gas operations for decades. 

The company’s strategic investor base continues to play a central role in its commercialization pathway. Toyota, Mitsubishi Gas Chemical, and ENEOS Xplora collectively hold approximately 11.6% of Gold Hydrogen, with Mitsubishi and ENEOS already operating large-scale dissolved gas extraction projects in Japan. 

Gold Hydrogen also outlined multiple commercial pathways under evaluation, including direct hydrogen supply, hydrogen-to-power generation, helium production for industrial markets, and longer-term green methanol production. 

The broader helium market backdrop appears increasingly important to the company’s positioning. Gold Hydrogen noted that supply disruptions at Qatar’s Ras Laffan complex have removed roughly one-third of global helium supply, while Australia remains fully dependent on imported helium following the closure of the Darwin helium plant.
