The TLS team weaves geoscience and AI, crafting proprietary tools that identify hidden geothermal systems. Humans began harnessing the power of fire long ago, and 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 overcome 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.
