Decahydron Secures Strategic Investment from Weatherford to Accelerate Natural Hydrogen and CO₂ Mineralisation Projects
Decahydron, an Ireland-headquartered cleantech startup operating in the United Arab Emirates and focused on unlocking natural hydrogen while permanently mineralising CO₂, has made a significant stride in its funding journey with a strategic equity investment from global drilling and energy services leader Weatherford International plc. The deal marks one of the most significant financial endorsements to date for Decahydron’s work in carbon-negative hydrogen energy and positions the company to accelerate its transition from exploration success toward commercial deployment at scale across the Northern Emirates and the broader Middle East and North Africa region.
Founded in 2022, Decahydron has developed a dual-purpose technology that extracts naturally occurring hydrogen from ultramafic rock formations while using the same geology to permanently lock away injected CO₂ through mineralisation. This approach aims to deliver abundant, low-carbon hydrogen and carbon removal in one integrated process. Prior to this investment, the company completed a major exploration programme that confirmed the presence of natural hydrogen at depth in Sharjah, UAE, laying the groundwork for future appraisal and commercial production phases.
The strategic investment from Weatherford follows a period of early-stage support from energy technology accelerators, including selection for the 2025 Rose Rock Bridge Accelerator — a programme that helped Decahydron refine its business model, deepen industry engagement, and position its solution for collaboration with major partners and potential investors.
Weatherford’s backing is widely interpreted within the energy community as a strong vote of confidence in Decahydron’s technology and commercial prospects. Under the terms of the partnership, Weatherford is acquiring an equity stake in Decahydron and contributing technical expertise in drilling operations, reservoir characterisation, and digital analytics — capabilities that are considered critical for moving efficiently into the appraisal and pilot-scale development phases. Joint committees comprised of both companies will oversee the development of pilot wells, data integration, and the establishment of commercial frameworks for larger-scale hydrogen production.
Decahydron’s CEO, Arnaud Lager, has said that Weatherford’s investment not only validates the company’s innovative approach to natural hydrogen and subsurface decarbonisation but also accelerates the timeline toward proof-of-concept and eventual commercial production. The company is now preparing to advance detailed resource evaluation and pilot well drilling activities in 2026, using the funding and technical support to tackle both scientific and commercial milestones.
In parallel with its financing progress, Decahydron has forged strategic collaborations with major industrial players to broaden its commercial footprint. The company has entered into agreements with Sharjah National Oil Corporation (SNOC) and Siemens Energy to study the feasibility of using naturally occurring hydrogen for power generation and other industrial applications in the UAE, further building confidence among prospective investors by demonstrating the real-world relevance of its technology.
These partnerships underscore a broader trend of capital flowing into technologies that combine climate mitigation with energy production, especially in regions seeking to diversify beyond conventional hydrocarbon systems. By leveraging partnerships with companies like Weatherford and Siemens Energy alongside national energy corporations such as SNOC, Decahydron is positioning itself as a pioneer in the natural hydrogen sector — a segment that has captivated both government and private capital attention due to its potential to deliver low-carbon energy at scale.
Decahydron’s pathway from a research-driven startup to a financed energy technology venture reflects an emerging ecosystem of investors and industry partners willing to support deep-tech solutions that address climate change, industrial decarbonisation, and future energy needs. As the company progresses into 2026, observers expect to see further milestones tied to project execution, expanded investor engagement, and possible additional funding announcements, especially as pilot production data becomes available and commercial frameworks are established.
The company’s strategic equity investment from Weatherford is a key early financial foundation that helps propel Decahydron toward its goals of proving natural hydrogen’s commercial viability and scaling CO₂ mineralisation globally. With hydrogen markets attracting fresh investment interest and national energy strategies increasingly incorporating carbon-negative solutions, Decahydron’s trajectory illustrates how innovative startups can secure meaningful backing when technology aligns with both climate imperatives and energy security demands.
