# Quaise Energy Raises $134 Million Series B for Superhot Geothermal AI

> Quaise Energy has raised $134 million in the initial close of a Series B to attempt something audacious: drilling deep enough to tap superhot rock and build what it calls the world's first commercial superhot geothermal power plant. The round was led by Prelude Ventures, with Japanese energy heavyweights JERA and Idemitsu Kosan taking part, lifting the company's total raised to about $230 million. The core technology comes out of MIT and swaps conventional drill bits for millimeter-wave energy that can bore through rock too hot and hard for normal equipment. AI helps guide the system as it reaches temperatures of 300 to 500 degrees Celsius at depths beyond five kilometers, the conditions where geothermal energy becomes far more powerful and economical. The appeal is that superhot geothermal could deliver clean, always-on power almost anywhere with the right geology, not just volcanic hotspots. It is very much a deep-tech bet with hard engineering still ahead, but the funding, and the backing of major power companies, signals real confidence that AI-assisted drilling can crack a problem the industry has chased for decades.
