Abstract
This master thesis investigated the feasibility of borehole thermal energy storage and solar
heating in the high arctic using Longyearbyen in Svalbard as a reference study place. Field
work was conducted in Longyearbyen, Svalbard to estimate thermal properties of ground.
Modelling of the energy storage was conducted to estimate the efficiency and environmen-
tal impact. Preliminary cost estimate was conducted to determine the economical feasibility
of the technology in the Arctic. Results of this thesis concluded that the borehole thermal en-
ergy storage is technologically possible in the Arctic environment. Cost estimate for the sys-
tem appears to be in the higher range, but not extraordinary high when compared to energy
prices worldwide. Main concerns related to implementing this technology is the thawing of
permafrost.
