Mantle8 confirms record hydrogen concentration in the Pyrenees

  • Mantle8 secures exclusive exploration rights in Comminges ahead of full license grant
  • Comminges results confirm accuracy of Mantle8’s predictive exploration technology

Mantle8, a natural hydrogen (H2) exploration company, has reported exceptionally high soil-gas readings at its Comminges prospect in the French Pyrenees, validating its proprietary exploration technology. The breakthrough signals a potential turning point for Europe’s long-term energy security, leveraging local, cost-effective and climate-neutral natural H2 reserves.

Mantle8’s proprietary technology is uniquely designed to identify complete H2-generating systems—its core differentiator. Unlike conventional exploration, it integrates geology, geophysics, geochemistry and numerical modeling to map the entire system: from the H2-producing source rock to the trapped subsurface reservoir, a world first. It also quantifies H2 volumes and assesses resource quality with unprecedented precision.

Mantle8’s modeling identified the Comminges area as a likely site for an active H2-generating system. Recent soil-gas test results of 2,500 parts per million (ppm) strongly validate the accuracy of the company’s technology, indicating active H2 generation and far surpassing the industry’s prospectivity threshold of 350 ppm.

“The Comminges block represents the perfect combo: an ideal pilot zone to validate our technologies, with a geological setting offering maximum hydrogen potential,” said Mantle8’s Founder and CEO, Emmanuel Masini. ”With these highly encouraging early results, we are well on our way to make $0.80/kg hydrogen a reality by 2030.”

Ahead of the full grant of the PER (Permit Exclusif de Recherche), expected by the end of 2025, Mantle8 will monitor the block for the production of H2 using low-impact exploration methods and the entire H2-generating system will be imaged, including reservoirs. This data will allow Mantle8 to accurately select sites for further exploration, reducing development time by 50% and cutting millions in upfront exploration costs.
