Three geothermal wells for warmth storage at a waste-to-energy plant in Salo, Finland is ready to start out supplying to the native heating community within the coming winter.
A geothermal warmth storage system on the web site of the Lounavoima waste-to-energy (WtE) plant in Salo, Finland is ready to provide warmth to the district heating community for this yr’s winter The primary section of the venture has been accomplished with three wells drilled up to now.
We had beforehand reported on the drilling of a 2000-meter geothermal nicely on the Lounavoima waste incineration plant which is meant to retailer warmth from the plant which may then be used for district heating provide within the winter. This was the second nicely of the venture, as a 1600-meter nicely had already been drilled and examined prior. Testing of the second nicely is ongoing. In the meantime, a 3rd nicely had been drilled within the winter of 2023 additionally to a depth of 2000 meters.
A call was made in June 2024 to spend money on a 3rd section, which entails the development of three further wells. Building work has already begun, and completion of the ultimate warmth nicely is anticipated by the summer time of 2025. The venture will then be totally accomplished.
The first funder of the venture is Salon Kaukolämpö Oy, which can achieve a big increase in environmentally-friendly power for its personal operations. The EUR 3 million in power assist granted by the Ministry of Financial Affairs and Employment kickstarted the venture.
Upon completion of the venture, the WtE plant can have six geothermal warmth wells with a mixed output of as a lot as 14 GWh per yr, or equal to the annual heating want of about 700 single-family properties. The geothermal warmth nicely venture has been carried out in cooperation with revolutionary Finnish firms, together with nicely know-how developer Quantitative Warmth Oy (QHeat) which has carried out different geothermal warmth initiatives in Finland.
The warmth wells have been drilled utilizing new drilling gear developed by Finnish firm Geomachine Oy for the venture. This gear made it doable to achieve the goal depth of two,000 metres. Finnish firm Calefa Oy delivered the warmth pump course of for the warmth wells.
“The warmth nicely manufacturing will at all times be used first if the district warmth output of the WtE plant isn’t sufficient. This enables us to primarily substitute the necessity for beginning oil heating crops and, in lots of instances, we will additionally keep away from the necessity to begin a backup energy plant,” explains Lounavoima and Salon Kaukolämpö Managing Director Petri Onikki.
“We now have such high experience right here in Finland. Although the brand new know-how improvement venture has not at all times gone easily, the outcomes have exceeded our expectations. The geothermal warmth wells have a multiplying impact on warmth manufacturing in Salo.”
