Who doesn’t love the smell of toasted bread in the morning? In this case, the biggest project the world has ever known will have you loving the smell of toasted rock. No, we have not gone mad! America is planning to drill the Earth to its core with high hopes of victory for geothermal energy as the next step in revolutionizing the transition towards renewable energy. Many years ago, this might have been something of mere science fiction, but today it is highly plausible.
America is planning the biggest project the world has ever known
We have heard of startups with some innovative and some quite ridiculous projects that promise clean energy. This startup’s project is equally innovative and ridiculous, but it just might work. American geothermal startup, Quaise Energy, is planning the biggest project the world has ever known.
Quaise is planning on using fusion technology to drill the deepest holes in history to unlock clean, virtually limitless, and essential geothermal energy that can re-power fossil-fueled power plants all over the world. Back in 1960, America planned on building a giant geothermal power-plant complex, but construction halted for decades. Currently, geothermal power only generates 0.4% of America’s electricity. Quaise plans on changing that.
Geothermal power is the next step towards clean energy
If a geothermal plant can access more underground heat, it can produce more energy. According to Paul Woskov, an MIT senior fusion research engineer, there’s so much heat below the Earth’s surface that using just 0.1% of it could supply the entire world’s energy needs for more than 20 million years. The Earth becomes hotter the closer you get to its core, but due to its extreme conditions, a few miles deep, traditional drill bits always break.
Quasie came up with a solution by repurposing the gyrotron, a tool used by the nuclear fusion industry. The gyrotron releases millimeter waves, which are classified between microwaves and infrared waves on the electromagnetic spectrum. In the early 1970s, researchers discovered that these millimeter waves were an excellent way to significantly heat plasma.
Quaise can achieve ultra-deep geothermal by using hybrid systems that combine traditional drilling with the gyrotron, while pumping in argon as an expulsion gas to clean and cool the bore while firing rock particles back up to the surface and out of the way. The company predicts they can drill holes up to 20 km (12.4 miles) deep to reach temperatures around 500 °C (932 °F), and expects the process can be achieved in 100 days. This is where geothermal energy will take a massive leap in efficiency.
When geothermal power plants are expected to be up and running
Quaise has officially started its first outdoor testing this year with its full-scale, field-deployable demonstration machines, and its biggest trial is planned for later in 2025, where they hope to achieve drilling 100 meters into a granite quarry near Austin, Texas.
The company joined forces with Nevada Gold Mines to initiate the incorporation of the technology into existing sites. They plan on pushing major funding to get a fully commercial power plant into full production.
Despite setbacks to its development process, Quaise’s goal to re-power a fossil-fired plant by 2028 persists. The company also plans on refining and replicating the process worldwide due to heat being accessible anywhere on Earth, thanks to its drilling technology. Approximately 8,500 coal-fired power plants are found worldwide, resulting in over 2,000 gigawatts of capacity, and must be repurposed by 2050, which means Quaise has its work cut out for it.
Science-fiction has become reality, and within a few years, it is plausible that Quaise will be able to use its laserbeams to cut deep into the Earth’s core. Soon, our planet could be primarily powered by geothermal power plants, a revolutionary step for sustainability.
