Decahydron Secures Weatherford Investment and Partners with SNOC & Siemens Energy to Advance Natural Hydrogen Projects in the UAE

Decahydron, a natural hydrogen and CO₂ mineralisation company headquartered in Ireland with operations in the UAE, has announced a series of landmark developments that position it at the forefront of the global geologic hydrogen industry.

At ADIPEC 2025, the company confirmed a strategic equity investment from Weatherford International plc (NASDAQ: WFRD) — a global leader in energy services and subsurface engineering — to fast-track its transition from exploration to commercial deployment. The partnership will accelerate the appraisal and development phases of natural hydrogen production and CO₂ mineralisation across the Northern Emirates and the wider MENA region, marking a pivotal step toward establishing a carbon-negative energy sector in the region.

The investment follows Decahydron’s successful completion of a 6,000-foot exploration well in Sharjah that confirmed the presence of natural hydrogen within ultramafic rock formations. The company is now preparing to enter the appraisal phase to demonstrate commercial production potential.

In parallel, Decahydron has entered into a collaboration agreement with Sharjah National Oil Corporation (SNOC) and Siemens Energy to assess the feasibility of using natural hydrogen directly for power generation and industrial applications in the northern Emirates. This study builds on Decahydron’s ongoing exploration with SNOC and aims to unlock new, zero-emission energy pathways for Sharjah and the UAE — including potential deployment for data centres and other energy-intensive facilities.

Arnaud Lager, CEO of Decahydron, stated:

“Natural hydrogen has the potential to transform the energy landscape. Our early findings suggest that this resource could redefine how clean hydrogen is produced — offering an abundant and continuous supply directly from the Earth. The time is right for the energy industry to unite around this new frontier, and the UAE is emerging as a leader in this transformation.”

Girish Saligram, President and CEO of Weatherford, added:

“Decahydron’s innovative approach to natural hydrogen and CO₂ mineralisation aligns closely with Weatherford’s commitment to energy transition and subsurface excellence. We’re proud to support the acceleration of this promising clean-energy pathway.”

H.E. Khamis Al Mazrouei, CEO of SNOC, commented:

“The potential discovery of natural hydrogen could mark a new chapter in Sharjah’s energy landscape — providing an abundant, naturally occurring source of clean energy and strengthening our role in the national energy transition.”

Through these partnerships, Decahydron is building an integrated model that couples natural hydrogen production with permanent CO₂ mineralisation, enabling a carbon-negative energy cycle powered by the Earth’s own geology. This strategy unites science, technology, and industry leadership to advance commercial-scale natural hydrogen projects across the UAE and the broader Middle East.

SNOC, Siemens Energy and Decahydron to Collaborate and Explore Natural Hydrogen Power Project in Sharjah, UAE

[Abu Dhabi, Nov 5, 2025] — Sharjah National Oil Corporation (SNOC) and Siemens Energy will collaborate with Decahydron, a natural hydrogen and carbon mineralisation company, to assess the feasibility of utilising natural hydrogen in power generation or other industrial uses in the northern Emirates.

The collaboration expands ongoing technical studies by Decahydron and SNOC on an existing exploration well in Sharjah to assess the Emirate’s natural hydrogen potential. Early results are encouraging, with drilling planned for 2026 in order to provide detailed resource data and measured flow rates.

The project will examine the use of natural hydrogen directly for power generation or other industrial uses, avoiding the costs of storage and transport while creating a new low-carbon energy source for the UAE which could be used for energy-intensive facilities such as data centres.

Decahydron is advancing a natural hydrogen and CO₂ mineralisation project in Sharjah and is working to validate the scale of the resource.

Siemens Energy will leverage its extensive expertise in energy technology to support the feasibility work, drawing on prior experience with hydrogen solutions. The company will also provide analytical insights to help assess the commercial potential and contribute to shaping the strategic direction of the project as it progresses toward potential implementation.

H.E. Khamis Al Mazrouei, CEO of SNOC, said: “We look forward to advancing this feasibility study in parallel with our ongoing exploration activities. The potential discovery of natural hydrogen could mark a new chapter in Sharjah’s energy landscape — providing an abundant, naturally occurring source of clean energy. If proven viable, it would not only strengthen Sharjah’s role in the national energy transition but also reaffirm SNOC’s commitment to driving sustainable, secure, and resilient energy solutions for generations to come.”

Khalid Bin Hadi, Managing Director UAE, Siemens Energy, said: “Hydrogen has the potential to be central to the decarbonisation of the power sector, and our technology is ready to enable this transition. This collaboration marks the start of a new initiative to explore the potential of natural hydrogen as a clean, sustainable energy source for the region.”

Arnaud Lager, CEO of Decahydron, said: “Natural hydrogen has the potential to transform the energy landscape. Our early findings suggest that this resource could redefine how clean hydrogen is produced by offering an abundant and continuous supply directly from the Earth. This is the right moment for the energy industry to come together and prepare for the opportunities that natural hydrogen will bring. Our work indicates that Sharjah and the northern Emirates hold exceptional potential, a finding also supported by independent research from the Colorado School of Mines and the Université de Pau.”

Decahydron Limited, an Irish headquartered, UAE operating, energy company pioneering natural (“white”) hydrogen exploration and subsurface CO₂ mineralisation, announced at ADIPEC 2025 that it has received a strategic equity investment from Weatherford International plc (NASDAQ: WFRD), a global leader in energy services and subsurface engineering.

The partnership marks a pivotal step in fast-tracking Decahydron’s transition from exploration success to commercial deployment. Together, the companies aim to accelerate the appraisal and development phases of natural hydrogen production and CO₂ mineralisation across the Northern Emirates and the wider Middle East and North Africa region, positioning the UAE at the forefront of a new carbon-negative energy frontier.

Decahydron has recently successfully completed a comprehensive exploration programme, integrating geophysical data with subsurface results from a 6,000-foot exploration well confirming the presence of natural hydrogen within ultramafic formations. The company is now preparing to advance into the appraisal phase designed to demonstrate commercial production potential.

“Weatherford’s investment is a strong endorsement of our vision to unlock the hydrogen potential of ultramafic rock formations,” said Arnaud Lager, Chief Executive Officer of Decahydron. “This partnership will accelerate our appraisal phase and chart a direct path to commercial production, bringing the world closer to abundant, carbon-negative hydrogen.”

“Decahydron’s innovative approach to natural hydrogen and CO₂ mineralisation aligns closely with Weatherford’s commitment to energy transition and subsurface excellence,” added Girish Saligram, President and Chief Executive Officer at Weatherford. “We are excited to support the acceleration of this promising clean-energy pathway.”

Through this collaboration, Weatherford will acquire an equity stake in Decahydron and contribute technical expertise in drilling, reservoir characterisation, and digital wellbore analytics. Joint technical committees will oversee the development of pilot wells, data integration, and future commercial frameworks for large-scale hydrogen production.
