The French government recently granted TBH2 Aquitaine an exclusive license to explore for natural hydrogen, helium and related substances, entitled “Sauve Terre H2”. This 225 km² area in the Pyrénées-Atlantiques represents considerable potential for “white” hydrogen, a decarbonized primary energy source naturally present in the subsoil.
A Rigorous Exploration Process
Exploration will begin with seismic surveys, followed by drilling in two to three years’ time, once new permits have been obtained. This approach reflects France’s commitment to clean energy, while ensuring the viability and environmental safety of the project.
White Hydrogen Versus Grey and Green Hydrogen
Unlike “grey” hydrogen, produced from fossil fuels, and “green” hydrogen, made from renewable but expensive electricity, “white” hydrogen is a promising alternative. It generates no CO2 and could play a crucial role in the decarbonization of industry and transport.
Global Expansion and Outlook
In addition to Pyrénées-Atlantiques, other permits are being considered in France, notably in Lorraine and Jura. Internationally, countries such as Spain and the United States are also interested in exploiting natural hydrogen, underlining a growing worldwide interest in this resource.
Pioneering researchers and companies, supported by appropriate legislation, are at the forefront of this quest. The discovery of constant flows of natural hydrogen at Bourakébougou, Mali, illustrates the renewable potential of this resource. Experts remain cautiously optimistic, calling for more research to fully assess the potential of natural hydrogen.
