Giant reserves of 'gold' hydrogen may be lurking beneath at least 30 US states, 1st-of-its-kind map reveals

A map of the United States showing regions that are likely (dark blue) and unlikely (white to light blue) to host hydrogen reserves, based on the geology.

A first-of-its-kind map of the United States has revealed the likely locations of huge, naturally occurring hydrogen reserves.

The map, which you can explore here, is the first to show prospective locations for hydrogen on such a huge scale, marking areas where hydrogen gas may be lurking beneath the surface in quantities large enough to extract.
