Abstract
A summary of ongoing geothermal projects and heat production from heat pumps is presented. The Lund project is still the largest geothermal plant in Sweden producing about 250 GWh/year and has been doing so for 25 years, Bjelm and Alm (2010). Utilization of heat pumps is by far the most common way of using geothermal energy in Sweden, Figure 1. With bedrock-soil- water source heat pumps about 12 TWh heat energy is extracted or about 15 % of the national heat demand is covered this way making Sweden a leading nation in heat pump based geothermal utilisation. The majority of the heat pumps are small and typically used in single houses, Nowacki (2007) and Lund, Bjelm and Bloomquist (2008).
