Geothermal energy and district heating in Ny-Ålesund, Svalbard
This thesis presents the possibilities for using shallow geothermal energy for heating purposes in Ny-Ålesund. The current energy supply in Ny-Ålesund is a diesel generator, which does not comply with the Norwegian government and Ny-Ålesund Science Managers Committee’s common goal to maintain the na...

This thesis presents the possibilities for using shallow geothermal energy for heating purposes in Ny-Ålesund. The current energy supply in Ny-Ålesund is a diesel generator, which does not comply with the Norwegian government and Ny-Ålesund Science Managers Committee’s common goal to maintain the natural environment in Ny-Ålesund.
