Key Findings
La Française de l’Énergie has reported significant hydrogen concentrations from the PTH-2 exploration well located in the Moselle basin of Lorraine. The primary data points recovered from the borehole show dissolved-hydrogen concentrations of 36.1 percent at a depth of 2,242 metres and 49.6 percent at 2,426 metres.
Technical Details
The drilling campaign targeted deep geological formations, with the PTH-2 well reaching a total depth of 3,655 metres. The recorded percentages of dissolved hydrogen serve as early indicators of enrichment at depth. To further validate these findings, the company has identified the following critical next steps:
- Conducting flow tests in collaboration with SYSPROG.
- Undergoing the process of resource certification.
Background and Context
The exploration is centered in the Moselle basin, specifically targeting areas beneath a former coal-mining district. This region is being evaluated for its potential to host natural hydrogen. While the initial readings from the 3,655-metre well are promising, the company notes that the current data represents early indicators rather than a fully characterized resource.
Significance and Outlook
The detection of hydrogen concentrations reaching nearly 50 percent at depths exceeding 2,400 metres provides a technical basis for further exploration in the Lorraine region. However, the company emphasizes that additional work is required to fully characterize the resource and understand its behavior over time. The transition from initial concentration readings to flow testing and certification will be the deciding factor in determining the scalability and stability of the hydrogen source in the Moselle basin.
