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.
The grant will support further development and scaling of the company’s technology platform, including expansion of the HOREX pilot project in Comminges, the establishment of an APoGeH geochemistry laboratory in Grenoble, upgrades to GeoLogix for improved subsurface imaging, and continued development of the Simul8 modelling platform, and Mantle8 also plans to recruit specialised researchers and conduct techno-economic studies with strategic partners.
All activities supported by the programme will take place in Grenoble and the wider Auvergne-Rhône-Alpes region. While the funding does not directly finance exploration campaigns, it is intended to accelerate the industrial development of Mantle8’s technologies so they can be deployed more efficiently and precisely.
