Quaise, Inc was founded in 2018 to develop a millimeter-wave drilling system for converting existing power stations to use superdeep geothermal energy.[1] The system repurposes existing gyrotron technology to drill 20 kilometers beneath the surface, where temperatures exceed 400°C. No fracking is required, avoiding the potential for earthquakes that have occurred in other geothermal systems.[2][3] Drilling using this technique is hoped to be fast, with boreholes aimed to be completed in 100 days[4] using existing 1MW gyrotrons.

Overview

Existing geothermal power stations can only be deployed in rare locations where adequate heat is located within 3km of the surface.[5] These resources are of a comparatively low temperature, and require seismically risky stimulation techniques. Further, drilling at these depths is expensive and slow.[citation needed]

Instead, Quaise plans to drill quickly to deep depths using a gyrotron and waveguide, vaporizing the rock by heating it.[citation needed] Temperatures at 20km depth are above the supercritical point of water, which allows ten times more energy to be transferred given the same volumetric flow.[6] The supercritical water is then used in a supercritical steam generator which may previously have been powered with fossil fuels.[citation needed]

Comparison with other power sources

The approach proposes advantages compared with other power sources:

  • Constant 24-hour generation - Maximum output always available. Does not require storage. Wind and Solar are intermittent generators.[citation needed]
  • Small land footprint - Consumes less than 1% of the land area of wind or solar for the same maximum output.[7]

Status

In October 2021, Quaise began initial testing of gyrotron boring at Oak Ridge National Laboratory[8] and plans to have a full-scale gyrotron drilling rig completed by 2024.[9] By 2026, the company hopes to have achieved 100MW of geothermal power output.[10] By 2028, Quaise aims to have converted an existing fossil-fueled power plant to run on geothermal steam.[citation needed]
