A brand new Gold Rush is taking form on a quiet stretch of Kansas prairie. There, a clutch of startups backed by the likes of Invoice Gates are looking out under the floor for naturally occurring hydrogen, a gasoline that may generate energy by way of climate-friendly means. Discovering it in huge portions might revolutionize a transition away from different fossil fuel-produced power. However the hunt is clear power wildcatting, with an actual chance of failure — and the added danger of diverting restricted local weather enterprise capital at a time when the world is in search of confirmed emissions-cutting applied sciences.
Kansas sits atop a geological quirk: The Midcontinent Rift is a subterranean scar a billion years previous created when North America began to separate down the center after which stopped. Iron-rich rocks inside the rift can produce hydrogen when uncovered to water, stress and warmth. And information left over from a number of previous oil exploration wells within the space a long time in the past present the gasoline is — or a minimum of was — current.
Tantalizing hints abound that different websites around the globe additionally home provides of the lightest aspect within the universe, attracting cash to the search. One firm, Koloma, has raised greater than $300 million, together with from Invoice Gates’ Breakthrough Power Ventures. Mining big Fortescue Ltd. not too long ago spent $22 million to purchase a 40% stake in Australia-based HyTerra, one of many startups wanting in Kansas. All informed, roughly 50 geologic hydrogen corporations are in operation, together with explorers, gear makers, and oil and gasoline conglomerates funding analysis, in keeping with BloombergNEF.
Naturally occurring hydrogen holds the potential for what Wooden Mackenzie analyst Richard Hood calls a “Spindletop second,” referring to the 1901 Texas oil gusher that helped create the trendy world. If it exists in business portions, pumping hydrogen from the bottom can be cheaper than stripping it from water utilizing electrical energy and cleaner than making it from pure gasoline, the commonest methodology.
“No query, there’s danger,” stated Bruce Nurse, co-founder of PureWave Hydrogen, which has leased websites in three Kansas counties for exploration. “However it’s an power supply we have to go after right here within the U.S., as a result of manufactured hydrogen just isn’t going to chop it.”

Scientists have begun earnestly making an attempt to find out how a lot hydrogen lurks underneath the Earth’s floor, and Geoffrey Ellis is on the forefront of that work. A analysis geologist for the US Geological Survey (USGS), Ellis spent 20 years researching petroleum geochemistry. About 5 years in the past, Ellis pivoted to hydrogen when he heard about Mali.
Mali is the good origin story of the hunt for geologic hydrogen, which trade refers to as “white” and typically “gold.” Within the late Eighties, residents of a village drilling for water within the West African nation of Mali stumbled upon a pocket of gasoline. Not figuring out what it was, they plugged it again up. A long time later, employees heard of this discovery and drilled a brand new nicely to uncover what they’d hoped was pure gasoline, solely to seek out practically pure hydrogen.
Ellis’s group has been modeling the subsurface globally — drawing on oil and gasoline trade instruments and strategies — and his estimate is wide-ranging: anyplace from billions of tons on the conservative finish to trillions of tons. Tapping even a fraction of the estimated hydrogen would meet a whole bunch of years of demand, Ellis stated.
He ascribes the a number of orders of magnitude of uncertainty to the character of the mannequin he and his staff constructed, primarily based on what is understood about hydrogen and better-understood assets like petroleum. The query for him — and traders and firms — isn’t whether or not it exists, however how a lot of it’s accessible and in a position to be amassed in giant, pure portions. The one approach to know for positive is to start out drilling.
“You need to function in uncertainty,” stated Koloma’s Chief Enterprise Officer Paul Harraka.
To maximise their possibilities of success, prospectors are leaning on paper information in dusty archives and oil and gasoline paperwork which have talked about unintentional hydrogen discoveries. However they’re additionally utilizing expertise like refined machine studying to establish what are referred to as “fairy circles” in satellite tv for pc photos. These round depressions on the Earth’s floor typically emit hydrogen and will level to subsurface reservoirs.
Viacheslav Zgonnik is the co-founder and former CEO of Denver-based Pure Hydrogen Power, which went prospecting in 2023 close to Geneva, Neb. Drilling greater than 11,000 toes into the bottom, they discovered hydrogen, although Zgonnik declined to say how a lot. However he left the corporate this 12 months to create a startup to supply software program to corporations on the lookout for hydrogen deposits.
“When there’s a gold rush, you promote picks and shovels,” Zgonnik stated.
A lot of the exploration occurring right now is within the U.S. and Australia, not simply because there’s proof hydrogen might exist underground however due to the 2 international locations’ supportive regulatory environments. Within the U.S., landowners have the rights to exploration permits fairly than the state, a stark distinction to different international locations the place government-controlled licenses can lead to lengthy delays.
Because of all these elements, many wildcatters are concentrated in Kansas and different states alongside the Midcontinent Rift. “It’s costly, and you’ll’t simply go digging random holes within the floor,” stated Mark Gudiksen, a managing associate at enterprise agency Piva Capital, which invested in Koloma. “So you need to be considerate about utilizing all the methods of the commerce.”
Even when prospectors hit hydrogen, its business prospects are extremely unsure. The explanation inexperienced hydrogen produced by renewable power hasn’t taken off but is due to its excessive price. The Division of Power has set a objective for hydrogen producers and prospectors to get prices right down to $1 per kilogram. That may unlock a wave of demand at present missing however important to rising the hydrogen trade.
The world at present makes use of about 94 million metric tons of hydrogen per 12 months, in keeping with BloombergNEF. The analysis agency forecasts that for the worldwide economic system to succeed in net-zero emissions by mid-century, hydrogen use will rise slowly, hitting 118 million metric tons in 2030, earlier than getting into a interval of fast progress. Worldwide use might attain 234 million metric tons in 2040 and 390 million metric tons in 2050, in keeping with BNEF’s New Power Outlook 2024.
“The market is de facto, actually, actually huge if the unit economics work,” stated Mark Daly, head of expertise and innovation at BloombergNEF. However that’s an enormous “if.”
One important price issue: purity. The nicely in Mali is sort of 100% pure hydrogen. However hydrogen is usually co-located with different gasses, together with helium. Australian firm Gold Hydrogen, for instance, stated it discovered hydrogen in addition to excessive ranges of helium in preliminary drill assessments carried out in 2023 on South Australia’s Yorke Peninsula and is now working to drill its first new wells. Whereas helium is a useful product, separating the 2 gasses provides expense.

One of many largest issues to bringing down prices is transport, which includes compressing the gasoline right into a liquid and trucking it or shifting it by underground pipelines. Each are costly and within the case of pipelines, nearer to fantasy than actuality. At excessive stress, hydrogen can react with metal pipes, inflicting them to develop into brittle and crack.
There’s additionally the potential for hydrogen leakage, a difficulty that scientists and startups haven’t but correctly confronted.
Hydrogen “is a really promiscuous gasoline. It diffuses everywhere,” stated Douglas Wicks, a program director on the Power Division’s Superior Analysis Initiatives Company-Power (ARPA‑E) who’s answerable for two geologic hydrogen analysis packages.
Transporting hydrogen is smart economically inside a 100-kilometer radius, stated Daly. He identified that elevating sufficient cash to construct a pipeline requires proof that the useful resource it’s transporting will exist for 20 to 40 years.
Many startups exploring in Kansas and Nebraska might overcome transportation points by promoting it regionally. The states are two prime agricultural producers, and firms see farmers as their largest potential prospects. Hydrogen found within the area might be transformed to ammonia, which is extensively used to make fertilizer.
The myriad unknowns usually are not stopping wildcatters. They’re additionally not stopping enterprise capitalists and enormous company traders alike from putting huge bets.
One of many trade’s largest boosters can also be one of the influential local weather tech traders in Breakthrough Power Ventures.
“The invention of geologic hydrogen might be one of many single most vital occasions in our lifetimes, and maybe the lifetimes of our youngsters,” stated the agency’s technical lead Eric Toone in a speech on the Breakthrough Power Summit in London in June. “It provides the potential of limitless zero-carbon reactive chemical power.”
That’s a part of the explanation the agency participated in Koloma’s $245 million Sequence B spherical, making it one of many largest startups on the hydrogen frontier. Nonetheless, traders acknowledge that the territory nonetheless comes with many unanswered questions, sufficient to offer many others pause.
If Koloma succeeds, “that adjustments the associated fee construction of hydrogen,” stated Gudiksen. However he additionally sounded a cautionary observe: “There’s completely an opportunity we could lose all our cash.”
