Drilling for hydrogen deposits

“If you had asked me four years ago what I thought about natural hydrogen, I would have told you ‘oh, it doesn’t exist,’” said Geoffrey Ellis, a geochemist with the US Geological Survey. “Hydrogen’s out there, we know it’s around,” he said, but scientists thought big accumulations weren’t possible.

Then he found out about Mali. Arguably, the catalyst for the current interest in white hydrogen can be traced to this West African country.

In 1987, in the village of Bourakébougou, a driller was left with burns after a water well unexpectedly exploded as he leaned over the edge of it while smoking a cigarette.

The well was swiftly plugged and abandoned until 2011, when it was unplugged by an oil and gas company and reportedly found to be producing a gas that was 98% hydrogen. The hydrogen was used to power the village, and more than a decade later, it is still producing.

When a study came out about the well in 2018, it caught the attention of the science community, including Ellis. His initial reaction was that there had to be something wrong with the research, “because we just know that this can’t happen.”

Then the pandemic hit and he had time on his hands to start digging. The more he read, the more he realized “we just haven’t been looking for it, we haven’t been looking in the right places.”

The recent discoveries are exciting for Ellis, who has been working as a petroleum geochemist since the 1980s. He witnessed the rapid growth of the shale gas industry in the US, which revolutionized the energy market. “Now,” he said, “here we are in what I think is probably a second revolution.”

White hydrogen is “very promising,” agreed Isabelle Moretti, a scientific researcher at the University of Pau et des Pays de l’Adour and the University of Sorbonne and a white hydrogen expert.

“Now the question is no longer about the resource… but where to find large economic reserves,” she told CNN.
A slew of startups

Dozens of processes generate white hydrogen but there is still some uncertainty about how large natural deposits form.

Geologists have tended to focus on “serpentinization,” where water reacts with iron-rich rocks to produce hydrogen, and “radiolysis,” a radiation-driven breakdown of water molecules.

White hydrogen deposits have been found throughout the world, including in the US, eastern Europe, Russia, Australia, Oman, as well as France and Mali.

Some have been discovered by accident, others by hunting for clues like features in the landscapes sometimes referred to as “fairy circles” – shallow, elliptical depressions that can leak hydrogen.

Ellis estimates globally there could be tens of billions of tons of white hydrogen. This would be vastly more than the 100 million tons a year of hydrogen that is currently produced and the 500 million tons predicted to be produced annually by 2050, he said.

“Most of this is almost certainly going to be in very small accumulations or very far offshore, or just too deep to actually be economic to produce,” he said. But if just 1% can be found and produced, it would provide 500 million tons of hydrogen for 200 years, he added.

This could be an important growth area for Texas drillers.  We are finding ways to sue hydrogen for energy rather than bombs.
