White hydrogen: a treasure beneath our feet and in the sights of scientists
The adventure of white hydrogen begins in the mysterious depths of the Earth. There, geological phenomena worthy of the biggest Hollywood productions come into play to generate this coveted gas. Unlike its colorful cousins (green, gray, blue, and so on), white hydrogen is not manufactured: it is extracted, like a secret as old as time finally revealed.
The most interesting part is that its origins are multiple. Among the main mechanisms, we find:
- ⛏️ Serpentinization: an effervescent meeting between hot water and iron-rich rocks, releasing generous amounts of hydrogen.
- 🌋 Mantle degassing: where volcanoes and faults are active, gas pockets rise quietly.
- 💧 Radiolysis: the magic of radiation that breaks the water molecule and thus offers an exit ticket to hydrogen.
This geological cocktail transforms our planet into a gigantic generator that almost naturally recharges itself. Geologists agree on a capacity for “continuous production,” with a quick cycle, in contrast to oil which takes its time (literally, millions of years!).
It is in this context that we better understand the buzz around the Folschviller well basin in Lorraine. Imagine this scene: researchers (not far from modern-day “Goonies”), in search of methane, hit the jackpot with 250 million tons of white hydrogen. From a geopolitical and scientific viewpoint, this is a game-changer.
