Does Norway use geothermal energy?

Geothermal energy use has increased in popularity in Norway. The total estimate of direct use of geothermal energy in Norway is 3.0 TWh. This represents 30 % growth since the 2015 WGC report. The majority of geothermal energy systems are geothermal heat pump (GHP) installations extracting or storing heat by BHEs in crystalline rocks.

How can we estimate the geothermal potential of Norway?

In order to estimate the geothermal potential of Norway we used our newly established heat flow database. Firstly, we selected the wells presenting the most stable heat flow values, thus potentially undisturbed by fluid circulations or undetected paleoclimatic signals (Pascal et al. 2009).

How many geothermal systems are there in Norway?

Today it is estimated that Norway has approximately 60 000 shallow geothermal systems in operation, producing 3.0 TWh of heat annually (Midttømme et al., 2020).

Is geothermal exploitation possible in Norway?

The potential for geothermal exploitation of tunnels in Norway is perhaps best evaluated by comparison with the current market activity and development of conventional borehole heat pump systems.

Which Nordic countries use geothermal energy?

Geothermal energy in the Nordic Countries. Shallow geothermal energy use is predominant in Sweden, Norway and Finland, while deep geothermal is predominant in Iceland and Denmark.

Why is there no geothermal power production in Denmark?

There is no geothermal power production in Denmark, due to low temperature levels in the aquifers. Shallow geothermal energy use is utilized, although not to a large extent, in Denmark since the late 1970s following the oil crisis. These GSHP systems, used for small residential buildings, are primarily horizontal ground loops.
