Belgium
A vast natural hydrogen deposit has been identified beneath parts of France and Belgium, a discovery experts are describing as “quite exceptional.” Preliminary estimates suggest the underground pocket could contain around 34 million tonnes of hydrogen — roughly one-third of current global annual hydrogen consumption.
The finding has sparked strong interest within the scientific and energy communities, as natural hydrogen — sometimes referred to as “white hydrogen” — could represent a major breakthrough in the transition to low-carbon energy sources.
Hydrogen is widely seen as a key component of decarbonization strategies, particularly for heavy industry, transportation, and energy storage. However, most hydrogen produced today comes from fossil fuels, a process that generates significant carbon emissions.
If the newly identified reserves prove technically and economically recoverable, they could offer a cleaner alternative. Unlike “gray” hydrogen (derived from natural gas) or even “green” hydrogen (produced via electrolysis using renewable electricity), naturally occurring hydrogen would not require energy-intensive production processes.
Despite the enthusiasm surrounding the discovery, significant challenges remain. Further geological surveys will be required to determine the exact size, accessibility, and purity of the deposit. Extraction methods for natural hydrogen are still in early stages of development, and environmental considerations will also need to be addressed.
Energy analysts caution that while the estimated 34 million tonnes is a striking figure, commercial exploitation will depend on technological feasibility, regulatory frameworks, and economic viability.
If confirmed and responsibly developed, this hydrogen reserve could strengthen Europe’s energy independence at a time when diversification of supply is a strategic priority. It may also accelerate investment in hydrogen infrastructure across the region.
For now, researchers are continuing their assessments. But the scale of the discovery has already raised hopes that Europe could be sitting atop one of the most promising energy resources of the future.
