Prominence Energy Gawler Hydrogen Project Receives Final Regulatory Approval

Prominence Energy Secures Final Regulatory Approval to Close Gawler Hydrogen Project Acquisition

Prominence Energy Ltd (ASX: PRM) has received the final regulatory approval needed to complete its acquisition of the Prominence Energy Gawler Hydrogen Project, marking a significant milestone in the company's strategic expansion into the emerging natural hydrogen sector. The South Australian Department of Energy and Mining has approved the transfer of Petroleum Exploration Licence 803, clearing the path for transaction completion.

The approval represents the culmination of a six-month regulatory process that began with the initial announcement in June 2025. Furthermore, with all hurdles now cleared, Prominence is positioned to close the transaction imminently and commence exploration activities on what could become a valuable natural hydrogen asset.

Strategic Entry Into Australia's Natural Hydrogen Frontier

The Prominence Energy Gawler Hydrogen Project acquisition positions Prominence Energy at the forefront of Australia's natural hydrogen exploration boom. Natural hydrogen, often called "white hydrogen," represents a potentially game-changing energy source that occurs naturally within the Earth and can be extracted using conventional exploration methods.

Chief Operating Officer Krista Davies highlighted the significance of this milestone: "The Company is delighted to have received the final regulatory approvals necessary to close the Gawler Hydrogen Project transaction. We anticipate closing the transaction shortly and progressing with our exploration efforts in the Gawler Hydrogen Project."

Key advantages of natural hydrogen:

• Zero-carbon emissions when combusted (only water vapour produced)
• Lowest production costs compared to manufactured hydrogen
• Renewable and non-polluting energy source
• Conventional exploration methods can identify accumulations
• Global presence with naturally occurring deposits worldwide

Understanding Natural Hydrogen: The Clean Energy Game-Changer

Natural hydrogen represents a revolutionary approach to clean energy production. In contrast, unlike manufactured hydrogen that requires significant energy inputs and infrastructure, natural hydrogen is formed through geological processes and accumulates underground in explorable deposits.

What makes natural hydrogen special?

Natural hydrogen forms through specific geological reactions occurring deep within the Earth's crust. Water reacts with iron-bearing rocks at high temperatures, producing hydrogen gas that migrates upward and potentially accumulates in underground reservoirs.

These processes occur naturally over geological timeframes, creating renewable hydrogen deposits that can be located using established exploration techniques. Consequently, the environmental benefits prove substantial compared to traditional hydrogen production methods.

Manufactured hydrogen typically requires either natural gas reforming (producing carbon emissions) or electrolysis (requiring significant electricity input). However, natural hydrogen extraction produces minimal environmental impact, with the primary byproduct being water vapour when the hydrogen is eventually combusted for energy.

Market potential remains significant as global governments commit to carbon reduction targets. Moreover, Australia's diverse geological settings provide favourable conditions for natural hydrogen formation, with several regions already showing promising indicators of subsurface hydrogen accumulations.

Prominence's Multi-Asset Energy Portfolio Strategy

The Prominence Energy Gawler Hydrogen Project acquisition aligns with Prominence Energy's broader investment strategy of securing high-ROI opportunities at ground floor valuations. The company's experienced team reviews numerous opportunities before selecting projects with exceptional potential.

Current portfolio highlights:

• 100% Working Interest in Big Apple Prospect, Gulf of Mexico (sizeable gas prospect)
• 20% interest in Umine
• 10% interest in ECOSSAUS Ltd (Australian salt cavern energy storage solutions)
• Gawler Hydrogen Project (pending completion)

This diversified approach across conventional oil and gas, hydrogen, and energy storage technologies positions Prominence to capitalise on multiple energy transition opportunities. In addition, the strategy focuses on early-stage acquisition of assets with significant development potential, allowing the company to secure projects before widespread market recognition increases valuations.

Next Steps and Exploration Timeline

With regulatory approval secured, Prominence Energy is moving toward immediate transaction completion and exploration commencement. The company's strategy focuses on rapid progression from acquisition to active exploration, leveraging proven geological techniques to assess the project's hydrogen potential.

Anticipated timeline:

• Immediate: Transaction completion following final approval
• Near-term: Commencement of exploration activities
• Medium-term: Resource assessment and development planning

The use of conventional, low-cost exploration methods means Prominence can begin evaluating the project's potential without significant upfront capital expenditure, maintaining the company's focus on capital efficiency. For instance, these methods include geochemical sampling, geophysical surveys, and potentially drilling to test subsurface hydrogen accumulations.

Investment Thesis: Positioning for the Hydrogen Revolution

Prominence Energy's entry into natural hydrogen exploration comes at a pivotal moment in the global energy transition. As governments worldwide commit to carbon neutrality targets, natural hydrogen offers a compelling solution that combines environmental benefits with economic viability.

Key investment drivers:

• First-mover advantage in Australian natural hydrogen exploration
• Proven management team with track record in energy sector opportunities
• Diversified portfolio across multiple energy transition technologies
• Capital-efficient exploration approach using established geological methods
• Strategic timing as natural hydrogen gains mainstream recognition

The company's ability to secure quality projects at early-stage valuations, combined with the emerging recognition of natural hydrogen's potential, creates a compelling investment proposition for energy transition-focused investors. Furthermore, natural hydrogen's cost advantages over manufactured alternatives could provide significant competitive benefits as the technology matures.

Australian Natural Hydrogen Sector Context

Australia's geological diversity makes it particularly prospective for natural hydrogen discoveries. Several regions across the continent show indicators of subsurface hydrogen accumulation, including areas with similar geological characteristics to the Gawler region.

The federal and state governments have expressed support for clean energy development, creating a favourable regulatory environment for natural hydrogen exploration. Consequently, this supportive framework enhances the viability of projects like the Prominence Energy Gawler Hydrogen Project.

Sector advantages include:

• Established mining jurisdiction with clear regulatory frameworks
• Geological expertise within Australian exploration companies
• Government support for clean energy initiatives
• Export potential to Asian markets seeking clean fuel alternatives

The timing appears favourable for companies entering this sector, as technological understanding advances and market demand for clean hydrogen alternatives increases globally.
