Quaise Energy, a geothermal technology startup, raises new funding to develop deep geothermal drilling aimed at extracting heat from “superhot” rocks far below the surface. Bloomberg reports the company secured $144 million, while The Next Web cites $134 million, describing a round intended to support drilling at depths of several kilometers rather than conventional shallow geothermal approaches. The Next Web says Quaise plans to use microwaves to heat or fracture the rock to enable access to geothermal energy. The reporting also indicates the fundraising is structured as a Series B, with Prelude Ventures leading the first close. Overall, the sources agree that the company is pursuing an enhanced method to reach hotter reservoirs underground and that the new capital is meant to advance the drilling technology and related development. The exact amount reported differs slightly between outlets, but both accounts characterize the investment as significant and focused on scaling a microwave-based approach for tapping deep superhot geothermal resources.
