Gold Hydrogen Prepares Flow Testing at Ramsay Project to Assess Natural Hydrogen Potential

Gold Hydrogen Limited is preparing to launch a flow testing program at its Ramsay project in South Australia, as it advances efforts to evaluate the commercial potential of naturally occurring hydrogen and helium resources.

According to a recent filing, equipment mobilisation is expected to begin in late May 2026, with flow testing operations scheduled to commence by late June. The program will focus on zonal testing of specific underground formations identified as containing natural hydrogen and helium, building on earlier subsurface analysis.

Preliminary data from the project has indicated unusually high concentrations of natural hydrogen, with soil gas measurements reaching up to 2,160 parts per million—around 4,000 times higher than typical atmospheric background levels. These findings have strengthened confidence in the presence of a potentially significant natural hydrogen system across the company’s extensive tenement holdings, which span more than 77,000 square kilometres.

Further supporting this view, early-stage fluid inclusion studies suggest the existence of regionally extensive hydrogen and helium generation systems. This raises the possibility that the Ramsay project could form part of a broader resource base, positioning it as a potentially strategic asset in emerging low-carbon energy markets.

Alongside the testing program, Gold Hydrogen is collaborating with Worley Limited to assess early-stage development options. This includes evaluating the potential to accelerate helium production from the site, which could help strengthen domestic supply and enhance Australia’s capacity in this critical industrial gas.

The growing interest in natural, or “white,” hydrogen reflects a broader industry trend toward exploring unconventional sources of clean energy that may require less processing than manufactured hydrogen. If successfully developed, such resources could offer a lower-cost and lower-emission alternative within the hydrogen value chain.

While the upcoming flow tests are a key milestone, they will be critical in determining reservoir performance, flow rates and overall commercial viability. The results are expected to guide the next phase of development planning for the Ramsay project.
