Mantle8, a European natural hydrogen exploration company, has received a €2.06 million grant from the European Union’s Just Transition Fund to support the development of its natural hydrogen exploration technology platform in Grenoble.

Founded in 2024 by Emmanuel Masini, Mantle8 develops geoscience-based technologies designed to identify potential natural hydrogen resources and analyse hydrogen-generating systems in the subsurface.

The company currently holds several exploration permits associated with potential natural hydrogen reservoirs and is working to advance technologies that could support future hydrogen production. Its programme builds on long-standing geoscience research in Europe, particularly in Grenoble, with the aim of translating scientific work into scalable industrial technologies.
