The TLS team weaves with geoscience & Ai to craft tools to identify hidden geothermal systems

Humans began harnessing the power of fire long ago. Geothermal energy represents a natural and significant progression in this technological evolution. Geothermal energy represents a natural and significant progression in this technological evolution.

Since 2012, TLS has been steadfast in its mission to uncover abundant, hidden geothermal resources. A decade of dedicated R&D has enabled us to develop sophisticated big data tools that jump this limiting barrier.
Our team’s DNA is a rich tapestry of expertise encompassing resource exploration, academia, geoscience technology, and project development. Together, we are committed to facilitating the energy transition for the betterment of people and the planet.

TLS is driven by strong values that prioritize climate protection, environmental management, and community well-being. We recognize geothermal energy as a key component in transitioning to a clean energy system. We will significantly reduce the cost of geothermal energy by increasing drilling success rates, accelerating development, and enhancing the resilience of energy systems.


Pioneering innovative geoscience concepts and developing competitive geothermal systems that provide sustainable, low-carbon baseload energy.

Cultivating a holistic approach to long-term environmental balance.
