EPFL engineers have examined the use of geothermal energy in two very different applications: a metro station and an underground data center. The works had a focus on the internal airflow conditions of these structures and possible optimization of the mechanical ventilation.

Engineers explore new applications for geothermal energy

Deep geothermal energy is climate-friendly and base-load capable - but how can this heat be tapped safely? ETH researchers are working on minimizing the earthquake risk and developing completely new systems, for example with closed CO2 cycles.
