Shallow geothermal energy system in fractured basalt:A case study from Kollafjørður, Faroe Islands, NE-Atlantic Ocean
A shallow (≈200 m) geothermal energy system is examined in the Faroe Islands, a 60-million-year-old volcanic archipelago in the Northeast Atlantic. The geothermal water has a heating capacity of approximately 150 individual households and consists of meteoric water approximately 3 years old. Water t...
