Geologic hydrogen, sometimes referred to as white, gold or natural hydrogen, refers to hydrogen gas that is found in its natural form beneath Earth's surface.
Last year, researchers found what may be the world's largest geologic hydrogen deposit to date in France's eastern Lorraine region.
The unexpected discovery further boosted interest in its clean energy potential.
Some have expressed skepticism about the clean energy potential of natural hydrogen.
Grey hydrogen — produced using natural gas and the most common form of hydrogen production — leads to large greenhouse gas emissions.
