H3 Energy Limited (ASX: H3E) is an Australian-based energy exploration and production company headquartered in Adelaide, South Australia. Formerly known as Whitebark Energy Limited, the entity underwent a significant rebranding and ticker change in December 2025 to better align its corporate identity with its evolving focus on the global energy transition. The company is primarily dedicated to the discovery and commercialization of traditional hydrocarbons, natural hydrogen, and helium resources across its diverse Australian permit holdings.
The company’s core operational assets include the 100%-owned Warro Gas Project in the Perth Basin of Western Australia, which represents a large-scale contingent gas resource located near existing pipeline infrastructure. In South Australia, H3 Energy maintains a dominant land position in the Officer Basin, where recent soil gas surveys have confirmed the presence of natural hydrogen and helium. Furthermore, the company is actively pursuing geothermal energy opportunities through exploration applications in southwest Queensland, targeting proven conventional hot water production sites for potential power generation.
Strategically, H3 Energy aims to capitalize on the projected domestic gas supply gap in Western Australia while establishing an early-mover advantage in the emerging hydrogen and helium markets. The company’s value proposition is built on a dual-track strategy that involves de-risking mature gas assets through advanced engineering solutions and exploring high-impact transition minerals. By catering to both traditional industrial energy users and the growing demand for carbon-neutral energy alternatives, H3 Energy seeks to deliver sustainable growth and diversified exposure for its shareholders.
