Native hydrogen, geological curiosity or future black gold

Hydrogen is destined to play a key role in the energy transition, either as an energy vector or as a zerocarbon source of energy. However, Hydrogen is still mostly produced from methane and there are yet only a few carbonfree methods of production (mainly electrolysis and plasma torch). Nonetheless, native Hydrogen does exist and naturally comes out from the ground in many places. The number of these places is even quickly increasing Eventually, if Hydrogen was indeed considered as a geological curiosity by many, the discovery of important flows and its production for a first time in Mali are changing the game.
