What is geoenergy? Geoenergy is renewable energy from sun which is stored to ground and also geothermal heat conducting from deep bedrock. Geoenergy can also be used as cooling energy. 100 m 7 °C 200 m 9 °C 300 m 11 °C 400 m 13 °C 500 m 15 °C 600 m 17 °C Picture: Temperature of the soil is depending on local weather conditions and thermal gradient of the bedrock.

Free cooling +1 °C +4 °C +15 °C +10 °C Average temperature of the energy well is usually between 0 – 8 °C Brine is used as source of cooling At the same time, heat energy is stored into ground. Cost for cooling is only the electricity for the circulation pump

Environmental politics in Nordic countries Sweden 2020 Renewables to 55 % of primary energy 2030 Lower green house gases 40 % compared to 1990 No fossil fuels in transport sector Finland 2029 No coal Half the usage of imported oil Renewables in transport sector to 40 % No oil for heating in government buildings 2025 Denmark 2030 No coal No oil for heating 2050 No fossils used Norway 2020 Heating oil ban 2030 Carbon neutral

Price of energy 65 €/MWh The price of district heating has doubled since 2001, and will continue to rise also in future. 50 €/MWh 20 €/MWh

Geoenergy as Investment Geoenergy investment is approximately 30–70 €/m2 (1-2% of total cost). Larger system is more cost efficient. Return of investment varies from 6 to 20% depending on project. Geoenergy investment is approximately 30–70 €/m2 (1-2% of total cost). Cost is affected by heating need of the building, heat distribution, peak power need, GSHP share of peak power and size of property. Investment cost / warmed area m2. Return of investment varies from 6 to 20% depending on project.  Profit is better eg. with underfloor heating, cooling used, system optimization, system monitoring and usage optimization

OUR PROJECTS Geoenergy is installed under the buildings Boreholes and horizontal pipes do not need any extra property, as they are installed under the building.

OUR PROJECTS Geoenergy also for tight places We have experience of installing geoenergy in e.g. garages and other tight places.
