Trillions of tons of buried hydrogen: Clean energy gold rush begins

There's enough natural hydrogen trapped underground to meet all projected demands for hundreds of years. An unpublished report by the US Geological Survey identifies it as a new primary resource, and fires the starter pistol on a new gold rush.

The "black gold" oil rush in the US started in 1859, when one Edwin Drake drove a stake into the Pennsylvania soil and oil started flowing out. The gold hydrogen rush may have a similar moment to point back to; in 1987, as one Mamadou Ngulo Konaré tells the story, well diggers gave up on a 108-m (354-ft) deep dry borehole, but he and other villagers in Bourakébougou, Mali, noticed that wind was blowing out of it. When one of the drillers looked in, smoking a cigarette, it blew up in his face, causing severe burns as well as a huge fire.

That fire, as Sciencequoted Konaré, burned "like blue sparking water, and did not have black smoke pollution. The color of the fire at night was like shining gold." It took weeks to put the fire out and plug the hole, but subsequent analysis showed the gas coming out was 98% pure hydrogen. Celebratory mangos were served. Some years later, a little 30 kW Ford generator was hooked up, and Bourakébougou became the first village in the world to enjoy the benefits of clean, naturally occuring hydrogen as a green energy source.
