Simulator for drilling at depths up to 5,000 meters

To tap into geothermal reservoirs, boreholes must be drilled deeply into the earth's crust. Due to the extreme pressures and temperatures involved, this is expensive and time consuming. A research team from Fraunhofer IEG ...

Cleaner air with geothermal energy

The use of dirty coal as a heat source makes life tough in the Mongolian winter. ETH geophysicists are helping to develop geothermal energy as a clean alternative.

Injection strategies are crucial for geothermal projects

The fear of earthquakes is one of the main reasons for reservations about geothermal energy. In order to get hot water from the depths, crevices in the rock underground often have to be created. This is done by injecting ...

Geothermal energy: Drilling a 3,000-meter-deep well

Although stopping climate change is challenging, it is imperative to slow it down as soon as possible by reducing greenhouse gas emissions. But how can we meet the growing energy demand while reducing our use of polluting ...

Reducing human-induced earthquake risk

Researchers at EPFL and the Swiss Federal Office of Energy have devised strategies for reducing the earthquake risk associated with geothermal energy, CO2 storage and other human activities happening deep underground.

Dutch aquifers bank rainwater to help farmers avoid going bust

Climate change is increasing the risk of water shortages across Europe, but researchers in the Netherlands are hoping to ease pressure by generating a steady supply of clean water and heat from deep underground reservoirs ...

Self-healing cement could transform geothermal industry

A self-healing cement developed by Pacific Northwest National Laboratory can outperform conventional concrete, offering a potentially pollution-preventing technology for the growing geothermal industry.
