Enhanced Geothermal Systems (EGS)

Overview

Unlike traditional geothermal which requires rare natural steam vents, Enhanced Geothermal Systems (EGS) drill miles into hot dry rock, inject water to fracture it, and pump up the heated water to drive steam turbines. EGS represents a massive untapped source of clean, continuous electricity.

Role in the Stack

It has the high energy density and reliability of nuclear power, but without the radioactive waste profile or regulatory red tape, making it highly attractive to technology companies.
