To make geothermal relevant in the energy transition, we need to drill deep enough to get an attractive rock temperature, to harvest the heat of that rock, and to efficiently convert it to electricity.  TechEnergy Ventures is supporting Quaise Energy, a start-up (MIT spinout) developing a drilling tech using a cutting-edge Millimeter-Wave (MMW) electromagnetic beam to dive into depths of ultra deep geothermal, and Eden GeoPower, a Massachusetts-based reservoir simulation technology company developing a groundbreaking electro-hydraulic fracturing technology to increase fluid permeability.
