Svalbard associated with darkness, cold and permafrost. But only a few hundred meters below the ground is a different story.
That Big Norwegian gladly exploit heating, and perhaps also to generate electricity.
Recently it became clear that Research gives 118 million to various projects in energy research. A portion of the pot goes to the mining company’s assessment of opportunities for exploiting so-called deep geothermal energy in Svalbard.
project is a collaboration with Christian Michelsen Research in Bergen and Research Norsar, working in geophysics.

Not as on the mainland

Project Malte Jochmann in Major Norwegian can tell that Svalbard has a unique geological profile, which makes use of geothermal energy for an opportunity.
– The project’s funny because Svalbard is so special. We have permafrost, but not as far below ground temperatures go up much. Not so on the mainland, said Jochmann to TU.
Below ground there are chances for finding limestone with hot water left in the cave systems. Do you get access to this water can be pumped up and used to heat buildings, both at Svea and Longyearbyen.

up to 80 degrees
– What we know is that one can expect 30-35 degrees at 1000 meters. If there are limestone here, then one has air cavity with hot water. I come from Munich, where one exploits the warm waters of the cave systems 1000-2000 meters below ground.
Johcmann says that there are hot springs on Svalbard, such as the one shown in the picture, but they are so far away from the roads and that it is not possible to utilize the heat from these.
First and foremost, geothermal energy going to heat buildings, but there may also be opportunities for power production.
– If you find an area with heating at 75-80 degrees, we can start talking about producing electricity, says Jochmann.

Collects information
Now scientists are facing a great job of gathering information.
– First we gather all the data that exists. So we’ll try to install gauges in wells previously drilled to test CO2 storage. So we hope to find a rock with a high geothermal radiant, and info about the differences in the geothermal radiant, says Jochmann.
old test wells are drilled approx. 800 meters down, but it’s a thrill how far down they stick, because some of the wells may have collapsed.

Also Kirsti Central Tender, Senior Scientist at Christian Michelsen Research, is excited about the project.
– There is a special project because Svalbard is the place in Norway where most violated CO2 emissions, both for heating and electricity. And the place has a vulnerable nature. Therefore, it is important to sweep his own door. Based on the data we have, it appears that there is relatively high temperatures.
She thinks it’s just good that coal company Store Norwegian focusing on green technology.
– The world goes on, the company wants to develop, and they have knowledge of the reason of Svalbard. Here one obtains resources from the ground, just in a slightly different form.
Kirsti Midttømme hope you can put in place a full-scale plant in the future. It will then be Norway’s first.
– Nowhere in Norway is current as animals, so this might be a Niche in Svalbard. We’d love to have demonstrated a deep geothermal plant in Norway.
