Discover Sage Geosystems' Subsurface Technologies for Geothermal Everywhere

At Sage Geosystems, we are dedicated to unlocking the potential of geothermal energy across diverse geological formations. Our innovative subsurface technologies allow us to harness geothermal resources using a single well EGS (Enhanced Geothermal Systems) design. With our approach, we eliminate the exploration risk associated with finding a hot aquifer and instead focus on drilling for temperatures of 150°C or above at economically feasible depths.

Explore our range of cutting-edge technologies designed to enable geothermal everywhere:

HeatRoot™ is a revolutionary downward-oriented fracture within our single well EGS system. Acting as a chimney, it efficiently captures heat from deeper and hotter formations. This technology specifically targets hot dry rock formations and offers the flexibility to circulate various working fluids through the fracture, based on the surrounding rock’s leak-off characteristics.

Our portfolio includes sCO2 technologies, featuring a patented sCO2 (supercritical) turbine. This turbine significantly reduces the power plant footprint while doubling the electricity output compared to conventional geothermal turbines. Moreover, our sCO2-refrigerant mixtures optimize net power output by minimizing parasitic loads from cooling, leading to improved overall efficiency. Additionally, sCO2 refrigerants offer a promising solution for carbon capture and storage (CCUS) by facilitating carbon injections into the Earth.

Utilizing the HeatRoot fracture, HeatCycle™ optimizes heat harvesting within each well. The working fluid undergoes alternating cycles of injection and production, while the fracture acts like a balloon, opening as it fills with fluid and closing during fluid flowback. This innovative approach enhances energy extraction efficiency and maximizes heat utilization.

HeatFlood™ is a hydrothermal-type well design specifically developed for formations capable of flowing hot produced water at high rates. In addition to generating geothermal power, this technology presents opportunities for water desalination and mineral extraction. By harnessing the potential of the production stream, we can unlock multiple benefits.
