Mantle8 has secured two natural hydrogen exploration permits in Spain, covering 960km² across Navarra and the Basque Country, as interest grows in Europe’s potential domestic hydrogen resources.

The permit area lies on the southern flank of the Pyrenees and features geology similar to the formations Mantle8 is evaluating through its Comminges permit on the French side of the mountain range.

For the company, the Spanish permits are not being viewed as isolated prospects. Instead, Mantle8 sees the wider Pyrenees region emerging as a coherent natural hydrogen province, where geological continuity across borders could help reduce exploration risk before drilling begins.
