St1 Deep Heat Oys Geothermal Heat Pilot Plant’s Role in Saving the Planet

In February, St1 Deep Heat Oy made an investment decision to construct a geothermal heat pilot plant in Otaniemi. The heat pilot plant is estimated to be completed in 2017. It is estimated to produce up to 40 megawatts of geothermal heat, which Fortum will buy to cover up to 10 per cent of the district heating demand in the Espoo area.

According to Mika Anttonen, Chairman of the Board of Directors of St1, “Research and development and new energy solution demonstrations are critical if we really want to boost Finland’s economic growth and replace imported fossil energy with domestic solutions. This geothermal heating pilot project is fully aligned with our strategy; the revenue from our traditional oil business enables us to make increasing investments in local renewable energy production.”

The fully emission-free geothermal heat could be the giant leap towards abandoning fossil fuels in heat production. District heating based mainly on fossil energy is the most common type of heating in Finland. As a result of this pilot project, bedrock could become a renewable energy source that can be utilized in the existing district heating network. The Espoo project is one of Finland’s spearhead projects in the field of renewable energy.
