A groundbreaking discovery in Northern France has the potential to ignite a renewable revolution in an unexpected place. A French shale gas company has unearthed a massive reserve of clean hydrogen gas, offering a glimmer of hope for regions heavily reliant on coal.

The discovery was made by Jacques Pironon and Phillipe De Donato, directors of research at France's National Centre of Scientific Research, during an assessment of methane stores in the Lorraine Basin. Surprisingly, they stumbled upon a previously unknown hydrogen gas deposit located 3,300 feet underground. The readings showed a hydrogen concentration of 20%, surpassing all expectations.

Hydrogen, when extracted and burned, produces only water as a direct emission, making it an attractive alternative to fossil fuels. While green hydrogen, produced through electrolysis and powered by renewable energy, remains a small-scale and expensive solution, the newfound deposit offers a different proposition.

Termed "white" or "gold" hydrogen, this geologic hydrogen could revolutionize heavy machinery and long-distance transportation. The hydrogen deposit in Mali, which powers an entire village, boasts a purity of 98%, setting a remarkable precedent.

Experts estimate that there are tens of billions of tons of extractable white hydrogen worldwide, potentially offering a sustainable energy source for hundreds of years. In France's Lorraine Basin, plans are underway to assess the extent of the deposit's potential. Energy company La Française de l'Énergie (FDE) is collaborating with researchers to evaluate the viability of extracting white hydrogen from existing shale gas wells.
