Imagine a hidden treasure trove of clean energy, right beneath our feet, waiting to be discovered. And the most fascinating part? It was found in a way that's anything but ordinary.
In the vast, rugged desert of western Nevada, surrounded by towering mountains, lies a secret. A secret that could revolutionize the way we power our world. But here's the catch: you wouldn't even know it's there just by looking at the surface.
A Utah-based startup, Zanskar Geothermal & Minerals, has made a groundbreaking discovery. They've located a massive geothermal reservoir, hidden thousands of feet underground, with the help of artificial intelligence. And this isn't just any old reservoir; it's a 'blind' system, meaning there are no visible signs of its existence above ground. No hot springs, no geysers, and no previous exploration attempts.
"The idea that geothermal energy is a thing of the past is a myth," says Carl Hoiland, co-founder and CEO of Zanskar. "We believe there are countless more hidden sites across the Western US, just waiting to be uncovered."
Geothermal energy is a game-changer. It offers an almost limitless supply of clean energy, producing minimal climate pollution. Unlike wind and solar, it's constantly available, not dependent on the weather. But the challenge has always been in finding and scaling these energy sources.
It requires a specific geological setup: hot water or steam reservoirs underground, along with porous rocks that allow the water to circulate and heat up. And that's where the real challenge lies.
In the late 1970s and early 1980s, there was a geothermal gold rush. Oil and gas giants invested heavily in drilling, hoping to strike it rich. But by the mid-80s, many had given up, discouraged by the high costs and low success rates.
"It's like finding a needle in a haystack," explains Joel Edwards, co-founder and CTO of Zanskar. "There's no single piece of data that tells you a system is there, even if you're standing right on top of it. It's a complex puzzle that humans struggle to solve."
And this is where AI steps in. Zanskar's AI models are fed data on existing blind systems, which humans have accidentally discovered while drilling for other resources like oil and gas. These models then analyze vast amounts of data, from rock compositions to magnetic fields, to identify patterns that indicate the presence of geothermal reserves.
"AI has gotten incredibly good at detecting these signals," Hoiland says. "It's like having a super-powered detective, able to see patterns humans might miss."
Once a potential site is identified, the next step is to drill down and confirm the existence of the reserve. This is exactly what Zanskar did at their 'Big Blind' site over the summer. They drilled wells to depths of around 2,700 feet and found porous rock at a scorching 250 degrees Fahrenheit.
"We know it's big enough to support a power plant," Hoiland says. "But we're still uncovering its true size."
There are still regulatory hurdles to overcome and grid connections to establish, but Zanskar estimates they could be producing electricity within three to five years.
James Faulds, a professor of geosciences at the Nevada Bureau of Mines and Geology, calls Zanskar's discovery "very significant." He estimates that over three-quarters of US geothermal resources are blind systems, and refining methods to find them could unlock tens or even hundreds of gigawatts of power in the Western US alone.
A 2008 government analysis estimated that undiscovered geothermal reserves in the US could provide around 30 gigawatts of power, enough for 25 million homes. But Hoiland believes the potential is much greater, possibly ten times higher.
Over the last three years, Zanskar has identified numerous 'hotspots' with similar characteristics to Big Blind across the Western US.
"We've only just scratched the surface," Hoiland says. "We expect dozens, if not hundreds, of new sites to be discovered in the coming years."
If Zanskar can keep costs down, it could attract significant investment. Geothermal has a unique advantage in that it can leverage the drilling expertise of the oil and gas industry.
"The political atmosphere in the US is also very favorable to geothermal right now," says Sophia Bauer, geothermal project manager at Global Energy Monitor. "Geothermal has flown under the radar, but it's expected to grow rapidly in the next few years."
The US leads the world in geothermal energy, accounting for about 24% of global installed capacity. But it still only makes up 0.4% of the country's electricity mix. There's a huge opportunity for growth.
Some experts believe geothermal could meet the soaring electricity demands of data centers, many of which power AI systems.
"Perhaps we're on the cusp of a future where AI is powered by geothermal, discovering even more geothermal resources!" Bauer suggests.
Zanskar's discovery is part of a geothermal renaissance. Much of the recent excitement has been around next-generation techniques, which use advanced oil and gas industry tools to drill deep and create artificial geothermal conditions.
But Hoiland believes conventional geothermal still has immense potential.
"AI could be a game-changer for the industry," says Joseph Moore, a geologist at the University of Utah. "If we can replicate Zanskar's success, it could unlock a whole new era of clean, renewable energy."
So, what do you think? Could this be the future of energy? Will AI-powered geothermal discoveries revolutionize the way we power our world? We'd love to hear your thoughts in the comments!
