For decades, geothermal energy has been the eternal promise of a clean and inexhaustible energy source. However, its development has been limited by the need to find locations with very specific geological characteristics, such as volcanic areas with heat sources close to the surface, like Iceland, relegating this technology to a secondary role in the global energy transition.
But what if we could access the immense heat of the Earth's interior anywhere in the world? That is precisely what Quaise Energy promises, a North American company that is revolutionizing the concept of geothermal energy with a technology that seems straight out of a science fiction novel.
Until now, conventional geothermal power plants have relied on the exploitation of hydrothermal resources, i.e., hot water and steam trapped deep underground. Traditional drilling, however, becomes extremely complex and expensive as depth increases, limiting access to these heat sources. This is where Quaise Energy's innovative approach comes in: drilling to extreme depths, between 3 and 20 kilometers, using a millimeter-wave system capable of vaporizing rock.
This technology, originally developed at MIT, is based on the use of gyrotrons, devices that generate high-power microwave beams. Imagine an invisible beam of energy capable of melting rock in its path, creating a deep well that allows us to access the intense heat of the Earth's interior.
At these depths, rock temperatures can exceed 350°C, enough to heat water and generate steam that drives conventional turbines and produces electricity. Essentially, it's replicating the process of a traditional geothermal power plant, but with an exponentially greater reach.

The promise of Quaise Energy is tantalizing: geothermal energy available anywhere on the planet, eliminating dependence on specific geological conditions. According to the company, its millimeter-sized drilling technology allows access to previously unimaginable depths, opening the door to a virtually unlimited source of energy.
In fact, scientists estimate that the heat stored beneath the Earth's surface contains enough energy to supply humanity's needs for millennia, and with Quaise's technology, we could tap a tiny fraction of that potential—less than 0.1%—to generate clean, sustainable electricity.
The viability of this technology will be tested in the near future at a former coal-fired power plant in upstate New York that is still connected to the electrical grid. Quaise Energy plans to repurpose existing infrastructure, including the turbine, to generate electricity from the geothermal energy obtained through its drilling system. If the pilot is successful, by 2026 we could be witnessing the dawn of a new era for geothermal energy. And the implications of this success are enormous.
Imagine a world where every coal or gas-fired power plant could be transformed into a geothermal power plant, leveraging existing infrastructure and minimizing environmental impact. The transition to a clean and sustainable energy mix would be dramatically accelerated, reducing our dependence on fossil fuels and mitigating the effects of climate change.
Furthermore, geothermal energy generation is constant, unlike intermittent renewable sources such as solar and wind, providing a solid foundation for grid stability.
Of course, there are still technical and economic challenges to overcome. The scalability of the technology, the cost of deep drilling, and the management of potential environmental impacts must be carefully evaluated. However, the potential of deep geothermal energy is so significant that it's worth exploring all possibilities.
Quaise Energy's vision is bold and, if realized, could change the global energy landscape. The prospect of accessing a virtually unlimited, clean, and available energy source anywhere in the world is too compelling to ignore.
If the tests in New York are successful, we will be witnessing a turning point in the history of energy, a giant step toward a more sustainable and prosperous future for all. Only time will tell if this promise becomes reality, but hope, like the heat of the Earth's interior, remains dormant.
It seems too good to be true.
