Gold Hydrogen Limited (ASX:GHY) explores and develops natural hydrogen and helium resources in South Australia. The company holds 100% ownership of the flagship Ramsay Project on the Yorke Peninsula, spanning 75,000 square kilometers under permitted exploration license PEL 687, along with eight petroleum exploration license applications and four gas storage license applications covering an additional 8,000 square kilometers; it has confirmed high-purity natural hydrogen up to 95.8%, helium up to 36.9%, and traces of helium-3 through drilling campaigns. Gold Hydrogen targets commercialization of these gases for clean energy transition, heavy transport, industrial applications, and high-value helium uses in semiconductors, optics, and space industries. Founded in 2021 and headquartered in Brisbane, the company operates solely in Australia with a focus on the Yorke Peninsula and Kangaroo Island regions. In July 2025, Gold Hydrogen secures a A$14.5 million strategic investment from Toyota Motor Corporation, Mitsubishi Gas Chemical, and ENEOS Xplora at a 22% premium to its market price, establishing partnerships for joint exploration, production, purification technologies, hydrogen supply for mobility, and potential green methanol development at the Ramsay Project; this funding supports a new drilling campaign launched in November 2025 targeting structural highs identified by 2024 seismic data to appraise commercial production potential. The company also receives a A$6.45 million R&D tax refund in early 2025 and expands its South Australian footprint with additional license applications.
