New drilling tech could unlock hotter, deeper geothermal power
Bipartisan legislation seeks to back the next generation of geothermal energy—especially enhanced geothermal systems (EGS)—to access hotter, deeper rocks. Companies like Quaise are testing millimeter-wave drilling and other advanced methods to cut costs and expand locations, while Fervo Energy advances pilot projects and Google signs power deals. Despite promise, economics remain challenging due to high upfront costs and water use, but advocates say higher temperatures could dramatically boost output and energy security, with policy support potentially accelerating liftoff.
