XGS provides Clean, Round-the-Clock Energy Everywhere, Forever
Our proprietary solid-state geothermal system uses thermally conductive materials to deliver affordable energy anywhere there is hot rock
What We Do
We are decoupling geothermal from dependence on water and geology.
1. Modular.
XGS’s smallest modular unit is a single well, pipe-in-pipe heat exchanger, in which working fluid, typically water, is circulated inside a steel casing, warms up, and then is returned to the surface through an inner insulated tube.
2. Water-independent.
Water is continuously recycled in zero-loss closed-loop.
3. Boosted by materials science.
Thermally conductive materials pull additional heat to the well for optimized economics.
4. In any geology.
Performance is not dependent on rock permeability and porosity.
