  2. 2. Rock cavern as thermal energy storage

    University essay from Luleå tekniska universitet/Energivetenskap

    Author : Simon Berglund; [2020]
    Keywords : Rock cavern; Waste heat; District heating; Intermittent operation; Sustainability; Heat storage; Carbon dioxide reduction; Bergrum; Spillvärme; Fjärrvärme; Intermittent drift; Hållbarhet; Värmelagring; Koldioxid reducering;

    Abstract : In the fall of 2019, a comprehensive idea study was conducted on heat storage in two rock caverns located at Näsudden in Skelleftehamn and was part of the project course "Energiteknik, huvudkurs" at Luleå University of Technology. This idea study investigated the conditions of using waste heat from Boliden AB:s copper smeltery (Rönnskär) and storing this waste heat in two rock caverns and use them as seasonal thermal storage tanks, with the purpose of using the heat in the nearby district heating network, thus replacing some of the oil burned at Rönnskär.
