Geothermal Energy

Geothermal energy – the renewable energy source from within.

Untapped potential from huge energy reserves
Geothermal energy is a renewable energy source with vast potential. It carries the benefits of low CO2 emissions, low running costs, local production and high security of supply. And after investments it has a long life. The geothermal reserves in the Copenhagen area in Denmark could cover 30-50% of the areas district heating needs for the next several thousand years.
 
Inside-Out: Capturing energy from the earth’s core
Geothermal energy comprises geothermal power and geothermal heat and is best utilised as base load. Power and heat is produced using heat from within the earth and utilized as steam and hot materials to heat buildings and generate electricity. Geothermal energy is divided into three systems:
 

  • Low-temperature - used for heat production
  • Middle and high temperature - for generating both power and heat
  • Hot dry rock technology - still being developed


From beneath the earth to Danish district heating
In Denmark, low-temperature geothermal heat is used in district heating as one of many energy sources. The technology utilises energy obtained from porous sandstone beneath some Danish cities. There are currently three geothermal plants operating in Denmark (in Thisted, Sønderborg and on Amager).
