″I believe that water will one day be employed as fuel, that hydrogen and oxygen, which constitute it, used singly or together, will furnish an inexhaustible source of heat and light.” So wrote Jules Verne in 1875. Visionaries and cranks have long searched for cheap ways to manufacture hydrogen, with limited success. Now the world is once more hyperventilating about the simplest element, but with a twist. Some modern visionaries don’t want to make it; they want to drill for it. A rush is starting for colourless gold.
Hydrogen is the most prevalent element in the universe, but isolating it is costoso. PA
Unlike gold, hydrogen is incredibly useful. As fuel, it can theoretically force cars, buses, planes, and ships. It can simply be burned to force plants to generate electricity. And since, unlike fossil fuels, they don’t emit greenhouse gases, they can limit climate substitution (as long as they are received blank).
Governments are subsidizing efforts to produce hydrogen. The US Inflation Reduction Act provides plenty for blank production from fossil fuels (which entails the tedious procedure of capturing and sequestering the carbon dioxide byproduct) as well as carbon-free nuclear energy. carbon and renewable energy (which requires a lot of force to split it (water into hydrogen and oxygen through electrolysis).
The challenge is that generating hydrogen through any of these strategies is expensive and will likely remain so for years to come. Hydrogen is the most prevalent substance in the universe but, according to the U. S. National Renewable Energy Laboratory, it is the most prevalent substance in the universe. According to the U. S. , it “does not exist freely” on Earth. It is generally found bound to oxygen, in the form of water, or to carbon, in the form of hydrocarbons. Releasing hydrogen can require a lot of energy, confusing equipment, and hassle.
So a motley crew of hydrogen hunters are searching for “natural” (or “geological”) hydrogen, which they believe is more common than is widely supposed. To those who dismiss them as dreamers, they point out that the notion of plentiful oil in the ground was once dismissed as crackpot, too.
The village of Bourakébougou in Mali is powered by hydrogen.
In the mid-19th century, the world faces an energy crisis. Whale oil is scarce. Some think oil could simply be a substitute, but many attempts to locate it have failed. When Edwin Drake proposed drilling for oil in Pennsylvania, investors scoffed at the idea: “Is oil coming out of the ground. . . ? Absurd! You. ” You’re crazy. ” Then one day in 1859, Drake had a boom and the oil era began.
Could something similar happen with hydrogen? To some extent, this is already the case. In 1987, in Bourakebougou, a remote region of Mali in West Africa, citizens in search of water drilled a hundred meters deep and, when the hole dried up, gave up. Then, to his surprise, a mysterious emission from that hole lit the fire. The well was temporarily plugged and forgotten, until a brilliant local businessman arrived.
“I need to be the hydrogen king!” Aliou Diallo whispers. The son of a railroad employee in Mali, Diallo made his first fortune by investing in distressed debts, transforming those profits into commercial concessions, and later acquiring a gold mine. He threw himself into politics, despite the risks in a coup-prone country like Mali, which ran for president in 2018 and came in a respectable third. But now he has abandoned politics to concentrate on hydrogen.
As luck would have it, the hydrogen-emitting hole at Bourakebougou was located within an oil and fuel concession awarded to a company run by Diallo. The villagers, seeing flames rising from the ground, thought the place was cursed. Diallo, who is not superstitious, to investigate. Tests showed that the well produced 98% natural hydrogen. Diallo brought equipment from Canada to do more drilling and testing. A coup in 2012 scared foreigners, but he pressed ahead. Now, those villagers have reliable lighting and electricity. , day and night: a rarity in rural Mali.
The well tapped into a large reservoir of natural hydrogen that continues to flow to this day. Diallo’s company drilled over two dozen more wells, from shallow ones akin to the first water well to ones 1800 metres deep, to map and master the geology. Hoping to replicate his success elsewhere, he has set up a company called Hydroma in Canada to scour more stable countries for the gas. (Mali has had two more coups since 2020.) “Hydrogen is the gamechanger for humanity,” he says.
Aliou Diallo, founder and chairman of Hydroma.
He no longer shares this view. Hydrogen has been discovered in Australia, France, the United States, Brazil, Colombia and Oman. A site in Turkey, believed to be the site of the original Olympic flame, has been burning for millennia thanks to an energy source that is now known to be rich in hydrogen. The Mid-Atlantic Ridge and the African Rift Valley emit this gas. And mysterious surface formations known as “fairy circles,” observed in the Carolinas, Poland and Western Australia, also appear to seep in.
Why haven’t these hydrogen resources been detected before?It may sound strange, but big oil corporations have never searched for hydrogen or deployed sensors to find it. Geoffrey Ellis of the U. S. Geological Survey (USGS) adds that, in addition to being odorless and colorless, the fuel is absorbed by microbes beneath the surface. Therefore, prospectors would possibly have to drill with the particular goal of finding hydrogen if they want to locate what’s hiding under their noses.
In 2020, Viacheslav Zgonnik, a Ukrainian-born chemist, published a review of educational literature showing that “molecular hydrogen is much more prevalent in nature than previously thought. ” Early Western scholars had focused on articles in English. Zgonnik, who speaks fluent Russian, searched for clues in the undigitized and untranslated paper archives of the former Soviet Union. After reviewing more than 500 studies, he made a breakthrough.
Much of the box studies conducted during the last century took place in the Soviet Union and were largely unknown to Western researchers. Soviet engineers discovered hydrogen not because they wanted to, but because they had another (and now discredited) theory. on the origin of oil. They believe it was generated from inorganic matter rather than crushed dinosaur bones. From this point of view, carbon in the Earth’s mantle would interact with hydrogen at intensity to produce hydrocarbons. Therefore, it made sense to look for hydrogen as a telltale sign of the presence of oil.
By one estimate, there are more than a dozen ways hydrogen could arise naturally, but only a few seem to have the highest probability of producing commercially exploitable deposits. Most promising, according to Dr. Zgonnik, is serpentinization: iron-rich rocks beneath the Earth’s surface react with very hot water to produce iron oxide and hydrogen as fuel; in fact, rust. This reaction has been well studied. Dr. Zgonnik’s company, Natural Hydrogen Energy, found a most likely location in Nebraska and drilled the world’s first wild well for hydrogen, to a depth of about 3,400 meters. Although the pandemic and currency restrictions have slowed it down (“very few investors are in a position to take this kind of risk,” he sighs), the company plans to re-drill the site soon with new partners.
Another theory, that of deep formation, holds that hydrogen is produced deep within the Earth’s core or mantle and seeps to the surface through cracks. Yet another, known as radiolysis, proposes that the power of radioactive rocks splits water into hydrogen and oxygen deep underground. Regardless of how hydrogen is formed, its molecules are so small and slippery that they can gently seep to the surface unless they get caught in a trap (e. g. , under a layer of salt) or feed on microbes.
Since the publication of Dr. Zgonnik’s paper, interest in hydrogen has been on the rise. The Geological Society of London attracted more than 200 experts to a convention on the subject in July. The U. S. Department of Energy, while proceeding to pump billions of dollars into hydrogen production projects, has concluded that “[probably] large amounts of geologic hydrogen exist in the Earth’s subsurface. “
Dr. Ellis of the USGS believes there may be enough to power the global economy for centuries. The USGS will soon release an assessment of the most promising sites, in other words, a treasure map.

Speaking to The Economist on the sidelines of the U. N. weather conference, Gates said of plant-based hydrogen: “It may just be gigantic, or it may just be a fiasco, but if it’s there. . . Wow!” That’s why it’s based on Koloma, which rejects trial and error in favor of a rigorous clinical framework. At Ohio State University, Tom Darrah, the company’s lead generation manager, and a team of researchers run feverishly on an ordinary-looking cinder block. building. Dr. Darrah has drawn up his own map of where he thinks herbal hydrogen can be found. He says there is “very little overlap” with the location of oil and fuel.
When asked what his theory is about the case, the bespectacled teacher jumps onto the blackboard and starts doodling. We use the wise technique [specific, measurable, achievable, realistic and time-bound goals],” he says, which is fostered through modelling of the subsurface used in the oil industry. By applying “hydrogen intelligence,” his company searches for source rock that may contain hydrogen, discovers traps and seals on top, and uses his long research experience to temporarily validate the effects in the lab.
When the USGS releases its treasure map, it will point its savage rivals in the right direction. However, he insists, his company has merit thanks to its systems approach, which includes advanced sensing tools, tank simulation and on-site hydrogen stimulation. He says he knows “what clinical questions to ask” to locate “real areas that can be drilled. “
In his spare time, Dr Darrah hunts deer with a bow and arrow. (He says he gets some of his best ideas in the woods.) At work, he is hunting something bigger. He does not want another Mali; he wants to find the Saudi Arabia of hydrogen, perhaps in America. It might, however, be in Australia.

“I have an unpopular view that science and innovation will most likely come to our rescue when it comes to climate, as they did with COVID,” says Lympne’s Baron Howard. Michael Howard, as he was once known, was a British oilman, leader of the opposition and environment minister. He is now president of Earth Source Hydrogen, a startup pursuing this elusive fuel in Australia. He insists his company doesn’t embark on random wildlife operations, but he does apply for licenses in promising spaces and conducts on-the-job training before drilling. You’re considering spaces close to primary mining operations, which would possibly need to buy fuel if you can locate it.
With enough hydrogen, you can do anything
Dr. Ellis of the USGS considers Australia “one of the spaces for exploration. “An Australian competitor, Gold Hydrogen, has just set the industry on fire. Nearly a century ago, diggers discovered hydrogen in South Australia and, unusually, took careful notes. After reviewing those notes, which showed incredibly high concentrations of fuel, Gold Hydrogen made the decision to drill in the same location. Neil McDonald, the head of the company, excitedly reports that early drilling data from October shows that there are still high hydrogen levels, just as they were in 1931. This suggests a long-term source or a giant deposit, he estimates. The gas can probably be mined directly, without the need for hydraulic fracturing or other confusing processes to get it out.
The basic maxim has already been answered, says Philip Ball of the Clean Air Task Force, a U. S. environmental group. “We temporarily agreed on the life of a giant amount of hydrogen,” he says, “because we located it everywhere. “is whether this can be exploited.
There is still great uncertainty about whether the dreams of hydrogen dreamers can come true. But it is imaginable that at some point in the future cheap, low-carbon fuel may become widely available.
Hydrogen has the highest power density of all chemical fuels and is also highly reactive, says Eric Toone, director of lead generation at Breakthrough Energy. This makes it powerful. It can simply be used to make products that are hitherto dirty, such as liquid fuels, metals, and ammonia.
With enough hydrogen, Dr. Toone believes it would be imaginable to produce starch without photosynthesis, which would revolutionize agriculture. Only nuclear fusion has comparable potential, he says, and he believes hydrogen is a less risky bet. “If you have enough hydrogen and it’s reasonable enough, you can literally do anything,” he sums up. Actually, Jules Verne would agree.
