>accessible hydrogen in the earth
These researchers say water-rock reactions deep within the Earth continuously generate hydrogen, which percolates up through the crust and sometimes accumulates in underground traps. There might be enough natural hydrogen to meet burgeoning global demand for thousands of years, according to a U.S. Geological Survey (USGS) model that was presented in October 2022 at a meeting of the Geological Society of America.
Critically, natural hydrogen may be not only clean, but also renewable. It takes millions of years for buried and compressed organic deposits to turn into oil and gas. By contrast, natural hydrogen is always being made afresh, when underground water reacts with iron minerals at elevated temperatures and pressures. In the decade since boreholes began to tap hydrogen in Mali, flows have not diminished, says Prinzhofer, who has consulted on the project. “Hydrogen appears, almost everywhere, as a renewable source of energy, not a fossil one,” he says.

At USGS, Ellis is working on answering that question. He thinks Earth produces orders of magnitude more hydrogen each year than the 90 million tons that humans manufacture. But it’s not only that flow that matters—it’s the size of the underground stock. “How much can be trapped in the subsurface that we can actually go after?” Ellis asks. “That’s a much more difficult question to answer.”
He and his USGS colleague Sarah Gelman gave it a try using a simple “box” model borrowed from the oil industry. The model accounted for impermeable rock traps of different kinds, the destructive effect of microbes, and the assumption—based on oil industry experience—that only 10% of hydrogen accumulations might ever be tapped economically. Ellis says the model comes up with a range of numbers centered around a trillion tons of hydrogen. That would satisfy world demand for thousands of years even if the green-energy transition triggers a surge in hydrogen use.
HIDDEN HYDROGEN
Does Earth hold vast stores of a renewable, carbon-free fuel?
