Emmanuel Masini is a geoscientist, entrepreneur, and Founder and CEO of Mantle8, a pioneering French deeptech company advancing the exploration and extraction of naturally occurring hydrogen as a low-cost, ultra-low-emissions energy source.

Emmanuel holds a PhD in structural geology from the University of Strasbourg and spent over a decade leading geoscience projects across Europe, North Africa, and the Middle East, including as an R&D Project Manager at TotalEnergies.

Before Mantle8, Emmanuel co-founded M&U, a geology research and consulting firm, and led the Orogen Research program, a major collaboration between Total, CNRS, and the French Geological Survey involving approximately 100 researchers.

Emmanuel has built Mantle8 into a recognized European deeptech leader, earning a spot on the Europe Top 50 DeepTech Founders to Watch list and securing exploration permits for some of the largest natural hydrogen reservoirs close to demand.

Mantle8 has raised a total of EUR 37M including a EUR 31M Series A round, completed the world's first 4D imaging of an active underground natural hydrogen system, and is targeting commercially viable hydrogen production at EUR 0.80/kg by 2030.
