XGS Energy, Inc. is a geothermal energy company that provides clean, round-the-clock energy solutions. Originally founded as Geothermic Solution LLC in Palo Alto, California, the company later moved its headquarters to Houston, Texas.
Quaise, Inc is developing a millimeter-wave drilling system for converting existing power stations to use superdeep geothermal energy. The system would repurpose existing gyrotron technology to drill 20 kilometers beneath the surface, where temperatures exceed 400 °C. No fracking would be required, avoiding the potential for earthquakes that have occurred in other geothermal systems. Drilling using this technique is hoped to be fast, with boreholes aimed to be completed in 100 days using existing 1MW gyrotrons. To reduce costs and delays, the company planned to establish its wells on the sites
Sage Geosystems Inc. is a geothermal baseload and energy storage company founded in 2020. The company is headquartered in Houston, Texas.
Endurance Energy develops subsea geothermal power systems to provide continuous, low-cost renewable energy for industrial sites, island nations, and data centers. The company utilizes seafloor-based infrastructure to harness thermal energy from tectonic activity, aiming to address global power shortages.
Dig Energy, Inc. provides software and machine controls designed to significantly reduce the cost of drilling by up to 80 percent, enabling accessible thermal energy options. Headquartered in Concord, New Hampshire, the company focuses on innovative technologies that streamline drilling operations and drive down energy exploration costs.
Eden GeoPower Inc. is a Somerville, Massachusetts-based company developing electrical reservoir stimulation technology to increase subsurface permeability for next-generation geothermal energy production.
