Superhot geothermal energy could unearth big power boost for the AI era

Geothermal energy has been used for thousands of years, powering heating systems as early as the 14th century. It's getting a big upgrade. Beyond geothermal, there's superhot geothermal, which uses ultra-deep drilling to access extremely hot rocks, extracting 5 to 10 times more power per well. Quaise Energy, a Massachusetts-based startup, is in the market developing the technology, which involves an electromagnetic beam that vaporizes rock. The company's systems are able to reach superhot geot

What role should oil and gas companies play in climate tech?

Standing on top of a drilling rig in the backyard of Nabors’s headquarters, I couldn’t stop thinking about the role oil and gas companies are playing in the energy transition. This industry has resources and energy expertise—but also a vested interest in fossil fuels. Can it really be part of addressing climate change? The relationship between Quaise and Nabors is one that we see increasingly often in climate tech—a startup partnering up with an established company in a similar field. (Another

The Download: how to melt rocks, and what you need to know about AI

Geothermal startup Quaise certainly has an unconventional approach when it comes to destroying rocks: it uses a new form of drilling technology to melt holes through them. The company hopes it’s the key to unlocking geothermal energy and making it feasible anywhere. Quaise’s technology could theoretically be used to tap into the Earth’s heat from anywhere on the globe. But some experts caution that reinventing drilling won’t be as simple, or as fast, as Quaise’s leadership hopes. Read the ful

This startup wants to use beams of energy to drill geothermal wells

This rock-melting drilling technology from the geothermal startup Quaise is certainly unconventional. The company hopes it’s the key to unlocking geothermal energy and making it feasible anywhere. Geothermal power tends to work best in those parts of the world that have the right geology and heat close to the surface. Iceland and the western US, for example, are hot spots for this always-available renewable energy source because they have all the necessary ingredients. But by digging deep enoug
