Projektet demonstrerer isoleringsevnen i vores DualVac™-teknologi, som er en vigtig del af Heat4Ever™-løsningen. Målet er at sikre minimalt energitab, når varmen transporteres fra mere end 3 km nede i jorden og op til overfladen.
Vi installerer DualVac™-systemet i den eksisterende brønd.
Data fra projektet skal danne grundlag for den videre udvikling af Heat4Ever™ og bane vejen for kommerciel udrulning i den geotermiske energisektor.
Samtidig undersøger projektet mulighederne for direkte anvendelse af geotermisk varme til fjernvarme. Det kan bidrage til en mere bæredygtig energiforsyning i byer.
Brønden blev udvalgt til projektet i midten af 2025, og vi er nu i gang med installationen. Herefter gennemfører vi et etårigt demonstrationsforløb, hvor vi tester forskellige driftsforhold for at dokumentere systemets ydeevne.
Vi gennemfører projektet i samarbejde med GFZ Helmholtz-Zentrum für Geoforschung ved forskningsanlægget Gross Schönebeck i Tyskland.
Green Therma står for udvikling og systemintegration, mens GFZ bidrager med geotermisk ekspertise og avancerede testfaciliteter.
The well is drilled using the same method as is used in oil drilling. A drilling rig with a 40-meter-high derrick is set up. In terms of area, the fenced site occupies about the same space as a football field. The “drill” that performs the well drilling is located in the derrick. The well has a diameter of approximately 1 meter at the surface. Drilling is carried out in sections, with each section gradually decreasing in diameter with depth. The drilling itself reaches 4–5 km of depth, with a horizontal stretch of 2–3 km. The drilling takes about three months and is conducted around the clock.
In addition, equipment needs to be transported to and from the site, and pipes need to be installed to connect the new facility to the district heating network.
Overall, establishing the well will take approximately six months if everything proceeds according to plan.
Drilling the well takes about three months. The full construction period with site activity will last about six months.
We expect the facility to be completed in 2027.
Before the well can be drilled, we need to conduct seismic surveys in the area around Storvorde. Small trucks will drive around on the roads and send pressure waves into the ground. This may be briefly noticeable. Each truck only passes the same spot once.
During the drilling phase, the construction site will experience increased traffic with trucks and large machinery.
Drilling the well is going to cause noise and possibly minor vibrations, without any risk to the surrounding buildings. Green Therma will work with the rig owner to explore options for soundproofing the components that are the primary sources of noise. Green Therma will involve the affected residents to examine possibilities for temporary noise barriers, soundproofing bedrooms, relocation, etc.
In addition, there will be lighting on the construction site. Drilling takes place over three months, and work on the site continues around the clock.
