St1

St1's pilot project to build Finland's first industrial-scale, emission-free geothermal energy heating plant involving drilling two boreholes to extract bedrock heat for district heating.

Technology that stores excess heat in deep geothermal wells during the cooling season for use during the heating season.

Drilling technology to reach depths of 7,000–8,000 meters to extract geothermal heat from bedrock for district heating systems.

A centralized heating system that distributes heat from a single source (in this case, geothermal) to multiple buildings via circulating water through pipes.
