TLS is dedicated to uncovering hidden geothermal systems using our proprietary, geoscience-driven machine learning tools. From the dawn of time, humanity has harnessed the power of fire; geothermal energy is a natural and profound advancement of this technological journey.

Since our founding in 2012, we have remained committed to our goal: discovering abundant, concealed hydrothermal resources. Resources we not only uncover but also manage throughout development and operations, ensuring sustained clean energy production for decades.

Our team’s DNA is woven from a rich tapestry of expertise that spans resource exploration, academia, geoscience technology, and project development, equipping us with robust adaptability for the clean energy future. Together, we are committed to facilitating the energy transition, benefiting our stakeholders and the planet.
