A groundbreaking discovery in northeastern France has revealed a vast natural supply of white hydrogen deep underground in the Lorraine mining basin. This discovery, made by researchers from France’s National Centre of Scientific Research and the GeoRessources Laboratory, could potentially hold between six million and 250 million metric tons of hydrogen. White hydrogen, which forms naturally through chemical reactions between water and certain rock types, is considered a clean and renewable energy source that does not release pollutants when burned, offering significant potential for industries aiming to decarbonize. The global interest in white hydrogen has been sparked by its environmental benefits and potential as a cornerstone in the clean energy transition. Different from other forms of hydrogen, white hydrogen occurs naturally and requires no emissions-intensive extraction process. This natural resource has attracted the attention of startups worldwide, with companies in South Australia and the US actively exploring its commercialization prospects. Despite the optimism surrounding white hydrogen, challenges such as regulatory uncertainties and production costs remain hurdles to widespread adoption. While current estimates suggest production costs could be as low as $1 per kilogram, accessing deeper reservoirs may increase costs, necessitating technological advancements for economically viable extraction. Geologists have identified natural processes like serpentinization and radiolysis as responsible for white hydrogen formation, with deposits found in countries worldwide. As technology advances, the possibility of efficiently harnessing this resource becomes more tangible, offering a promising solution for transitioning away from fossil fuels and addressing climate change on a global scale.
