Fervo Energy has demonstrated a 143% increase in drilling rates at its Cape Station project in Utah. The company’s latest well, Sawtooth 7, reached a depth of 19,448 feet in only 21 days—a 70% reduction in time compared to previous designs. By targeting hotter rock at 460 degrees Fahrenheit, Fervo is tracking toward an installed cost of roughly $5,500 per kilowatt for its upcoming phase, with future projections dipping to $3,000 per kilowatt. This efficiency stands in stark contrast to the Georgia Vogtle nuclear units, which faced extensive delays and final costs ranging between $10,000 and $15,000 per kilowatt.

Simultaneously, Quaise Energy has secured $134 million in Series B funding to advance its millimeter-wave drilling technology. With total funding now reaching $230 million, the company is preparing Project Obsidian in central Oregon. Quaise successfully penetrated over 100 meters of granite in Texas test wells, moving toward its goal of accessing superhot rock exceeding 300 degrees Celsius. As data centers demand consistent, non-intermittent power, these firms are positioning geothermal as a faster, more cost-effective alternative to the slow-moving nuclear sector.
