Country Update: The use of geothermal energy for district heating started in Klaipeda in 2000 on the Baltic coast. The absorption heat pumps use a lithium bromide solution. Low-temperature geothermal heat is extracted from water in the Devonian aquifer. The plant operating capacity is given as 35 MWt of which 13.6 MWt is from geothermal (installed geothermal capacity is 18 MWt). The plant is still solving difficulties with injection and struggling with the market – as it only operates during the heating season. The number of small-scale ground-source heat pumps in the country is growing. At present there are 5,500 installations, mainly by private companies. New construction of the logistics Center “Wurth Lithuania” included a 140 kW heating and cooling system using heat pumps. The installed capacity of small scale heat pumps is 76.6 MWt and annual energy use of 678.8 TJ/yr, and for the Klaipeda plant 18 MWt and 34.1 TJ/yr for a total of 94.6 MWt and 712.9 TJ/yr (Zinevicius, et al., 2015).

In June of 2004 the State Commission confirmed that the plant capacity for the Klaipeda geothermal demonstration plant on the west coast of the country was 35 MWt, of which 18.0 MWt was from geothermal energy. Four absorption heat pumps (at 4.5 MWt each) extract energy from 39oC geothermal water which is boosted to 175oC by three natural gas hot water boilers (16.2 MWt each). The heat energy is then supplied to the local district heating system. The installed geothermal capacity for the Klaipeda plant is 18.0 MWt (now operating at 13.6 MWt) producing 105.80 TJ/yr.

In addition there are a number of smaller geothermal heat pumps units in single family houses throughout the country adding 34.5 MWt and 305.72 TJ/yr.

The total for the country is 48.1 MWt and 411.52 TJ/yr.
