Klaipėda Geothermal Demonstration Plant fuel, and reduce CO emissions by 51,940 tons, NO by 11 tons, and sulfur dioxides by 1,160 tons per year if it additionally replaced heavy fuel oil. According to this estimate, the plant would satisfy about 10% of the city's heat demand. The potential for geothermal heating using the source aquifer arises from the Gotland tectonic belt and Polotsk–Kurzeme fault belt interface in the area, which generates thermal anomalies. The plant uses water from a well drilled into a Devonian aquifer about beneath the surface. The heat is extracted using an absorption heat pump, and circulates in a closed loop.
