Renewable, low carbon energy sources are not only in the center in the fight against climate change, but they provide also cost-effective and stable energy solutions. Among them, geoenergy is regarded as the most cost-effective and energy-efficient solution even in a typical situation where the drilling has to be started from the ground level. Therefore, using existing operation environment such as the depth of Pyhäsalmi mine, 1445 m underground do not offer only unique environment with large-scale possibilities but creates competitive edge to create and use green technology solutions.

Energy mine –project, leaded by Geological Survey by Finland and funded by ERDF, examines possibilities to utilize bedrock heat of the depth range 500 – 2500 m using Pyhäsalmi mine as the research target. At this depth-range, heat content of the bedrock is larger than near the surface, also new more effective methods for heat collection can be developed and tested in underground conditions.

Project is still ongoing, preliminary results show that Pyhäsalmi mine is not only interesting piloting place located with good connections and infrastructure surrounded with beautiful nature. It is also promising place for any business activities that can exploit geothermal energy collected from warm water – that is already 20-30 degrees Celsius and the temperature can be profitable increased with a heat pump. That really gives you 1500 metres head start – would you be interested to discuss the possibilities that Pyhäjärvi can offer for you businesses?

Pyhäjärvi, Finland. Located in the one of the deepest known places in Europe, in the depth of Pyhäsalmi mine, a new business operation environment called Callio has started. It offers one of fewest underground research facilities in the whole world. An underground operation of Pyhäsalmi mine in Northern Ostro-Bothnia is estimated to get closed at the end of 2019. Callio has a huge potential to transform the area into a cutting-edge centre for commercial and scientific use.
