Terrensis is a pioneering natural hydrogen exploration company founded in 2022 by highly experienced entrepreneurs who are among the most seasoned leaders in this emerging sector. With more than a decade of unique expertise — including, as technical advisors, the design and implementation of the first natural hydrogen discovery — the founders bring unmatched scientific, technical and operational know-how. The company is now focused on achieving a second major discovery, targeting a large hydrogen gas accumulation in the Western Pyrenean foothills, one of the world’s most promising exploration areas. Terrensis made history in December 2023 by securing the first exclusive natural hydrogen exploration permit in France, named “Sauve Terre H²,” through its subsidiary TBH2 Aquitaine. The company collaborates with leading research institutions and is recognized for its deep technical know-how.
