Nordic Council Nature and Environment Prize

Chair of Board Mr. Jákup Suni Lauritsen and CEO Mr. Hákun Djurhuus

Motivation:

“The prize goes to the Faroese electricity company SEV for its ambitious targets and innovation. SEV’s work is not only important for the phasing in of renewable energy in the Faroe Islands, but also for the European grid as a whole. Its ambitious targets and the creative nature of its efforts to reduce dependency

  • n fossil fuels make SEV a worthy

recipient of the Nordic Council Nature and Environment Prize 2015.”

HiddenFjord - Fútaklettur Salmon Farm delivering superior quality salmon. Power Hub controls the heat pump that keep the newly born salmons at the right temperature before they are send out (35 kW heat pump) Bergfrost Bergfrost is a cold storage where all kind of frozen marine products is kept. The cold storage is build in a mountain cave. Care for the environment was the primary reason for blasting tunnels from the mountain for the cold store. It was felt that the blot on the landscape would be too visible if the quarry in Fuglafjørður was extended northwards. Far-sighted council members came up with the idea of going further into the mountain for stones. (150 kW cooling compressor) Kollafjord Pelagic Receives freshly caught fish and freeze it. The facility in Kollafjørð is one of the world’s largest and most advanced processing facilities for human-consumption pelagic fish. (4.200 kW cooling compressors)
