- Natural hydrogen confirmed across multiple intervals with rising concentrations beyond 2000m.
- Deepest dedicated hydrogen exploration well globally reaches 3655 m.
- New 2254 km² permit strengthens pathway toward industrial scale development.
La Française de l’Énergie has confirmed the significant presence of natural hydrogen following the successful completion of its PTH-2 deep drilling project in the Moselle section of the Grand Est region in France.
The well, drilled to a depth of 3655 m, is currently the deepest in the world dedicated specifically to natural hydrogen exploration. The milestone reinforces growing global interest in naturally occurring hydrogen, often referred to as white hydrogen, as a low cost and carbon free energy source.
During the drilling campaign, hydrogen was detected across multiple geological intervals, confirming its widespread presence. Preliminary analysis shows a marked increase in concentrations from depths of around 2000 m, indicating strong potential for commercially viable extraction.
The project has also delivered important scientific insights. A total of 58 surface samples were collected alongside extensive subsurface logging data. These findings are expected to improve understanding of hydrogen generation, migration and accumulation within the Lorraine basin.
In a parallel development, FDE secured the Trois Évêchés exploration permit, covering 2254 km² for an initial five year period. This expands the company’s footprint in the basin and supports continued appraisal activity.
Data gathered from the PTH-2 well will now be used to support certification processes required for future industrial scale development. The company also plans to advance detection technologies toward patented production tools, positioning itself within an emerging natural hydrogen value chain.
The discovery builds on earlier results from the Folschviller well in 2023 and strengthens France’s position as a potential leader in natural hydrogen. With rising demand for clean energy solutions, the resource could offer a competitive alternative to conventional hydrogen production methods, particularly in markets seeking scalable and low emission energy options.
