Geoenergi: Pumping cash savings out of the ground


About geothermal energy

  • Large amounts of energy from the sun and the earth’s core are stored in the bedrock.
  • With the aid of heat pumps and heat exchangers, this energy can be used to heat and cool buildings.
  • A typical geothermal system from Geoenergi usually pays for itself in 4–8 years.
  • In Scandinavia, closed systems with a circulating fluid are the most common. This system has a lifespan of over 50 years.

Promising results in service
Moov-In, a student residence in Drammen, shares a geothermal system with Union eiendomsutvikling, a property development company. The developer and SIBU, the Buskerud students’ association, have set up a joint venture, Union Energi, which also supplies heat to several neighbouring premises, including an Ultra grocery store.
“The key to a stable and reliable geothermal energy supply lies in thoroughly understanding the system,” says Wilhelm Huus-Hansen, Geoenergi’s marketing manager. “We’re one of the few companies that supply customized turnkey solutions. For optimum performance and low running costs, the building, the wells and the heat pump have to be compatible.”

Growing market
Geoenergi expects its market to grow significantly in the years ahead. For one thing, the TEK 07 building regulations will bring about big changes, as developers are forced to cut the energy consumption of new buildings. This should stimulate interest in new technologies and solutions. Geothermal energy is a world-class solution. Nothing beats it on profitability or sustainability,”says Mr Huus Hansen.

Two-page feature in business press
Finansavisen, a Norwegian business newspaper, carried a two-page feature on Geoenergi in a special supplement published 7 October 2009. This was part of a week of coverage of renewable energy technology, to coincide with the NEREC North European Renewable Energy Convention held at Lillestrøm on 7–8 October
