en.Wedoany.com Reported - French energy company La Française de l’Energie (FDE) has measured hydrogen concentrations of up to 49.6% in the PTH-2 well located in the Moselle department, and the project has officially entered the industrial development phase.

In-situ exploration data from the PTH-2 well released by FDE shows that the well reaches a depth of 3,655 meters, making it the deepest well globally specifically drilled for natural hydrogen resource exploration. Test results indicate that the concentration of dissolved hydrogen in the formation increases with depth. At a depth of 2,242 meters, the hydrogen concentration reached 36.1%; at a depth of 2,426 meters, the concentration set an exploration record, reaching 49.6%.
These exploration results confirm the economic viability of natural hydrogen resource development and validate the reliability of FDE's proprietary SYSMOG detection technology. Based on these results, the group has significantly reduced the geological risk of its "Trois Evêchés" exploration block, which covers an exploration permit area of over 2,200 square kilometers.
FDE has partnered with Teréga Solutions to conduct a feasibility study for extraction infrastructure. The group plans to conduct downhole flow tests in the second half of 2026, complete an independent third-party certification of reserves in 2027, and aims to achieve commercial production between the end of 2028 and early 2029.
