Geothermal Country Notes
Sweden's utilisation of geothermal heat is on a very limited scale. Lund, in the far south of Sweden, has had a 4 MWt geothermal heat pump providing base-load heat to a district heating network for the past 20 years. A venture at the Lund scheme, the Deep Geothermal Project, plans to utilise deep water with a temperature greater than 100°C for direct heat application in the existing plant. Another project in Malmö, also in the far south, plans to extract geothermal heat by means of an absorption heat pump.
There are many small ground-source heat pumps installed in the country. It has been estimated that by 2005 some 275 000 (average size, 12 kW) had been installed in residential buildings. Some 600 larger pumps (average size, 900 kW) have been installed in district heating schemes.
