Geothermal Heat (ATES and deep geothermal)

Geothermal heat

Geothermal heat comes from the Earth’s interior and can go down to more than 5 kilometers deep. It is a renewable and clean source of energy that can be used for various purposes, such as heating, cooling, or electricity generation.

Geothermal heating is a highly climate-friendly heat source for district heating. When paired with renewable power from solar or wind, geothermal heating is not just carbon neutral; it is essentially emission-free. Moreover, geothermal heating is always there, and the underground reservoir is its own storage facility, making it ideal as a baseload in district heating. Once a plant is up and running, there is no pollution, noise, smell, or waste, making Geothermal heating a good neighbour in the city.

Advangates of geothermal heat

Geothermal heat has many advantages, such as:

  • It is available 24/7, regardless of weather or season.
  • It is environmentally friendly, producing low or zero greenhouse gas emissions and air pollutants.
  • It is cost-effective, as it reduces the dependence on fossil fuels and provides stable and affordable energy prices.
  • It is versatile and can be used for different applications and scales, from small homes to large industries.

Geothermal drilling can face several challenges, such as high temperatures and pressures, hard and abrasive rocks, lost circulation, and induced seismicity. Therefore, it requires specialized drilling equipment and skilled expertise.
