Digging deep for super hot geothermal

Despite its ability to deliver ample carbon-free energy, the potential of geothermal and EGS is limited by the number of drilling sites close enough to the earth’s surface. But a few pioneering companies have landed on a potential solution: dig way deeper. In this episode, Shayle speaks with Carlos Araque, the founder of Quaise Energy. The company has developed millimeter-wave drills to vaporize rock, allowing them to dig up to twelve miles underground in search of water around 800 degrees Fahrenheit. That super hot and "supercritical" water packs a huge punch: ten times more energy density than traditional geothermal. Shayle and Carlos explore a range of topics, including: Why 800 degree water is the “ideal” temperature for deep geothermal How "activating" permeability in deep rock differs from traditional fracking The state of Quaise’s Oregon project pilot, including their goal of a commercial-grade flow test by the end of 2026 How the LCOE of super hot geothermal compares to traditional baseload energy sources Resources Catalyst: How geothermal gets built Open Circuit: Is this geothermal’s breakout moment?
